The bender matters more than the tube. Two shops can buy identical 1.75 inch DOM and come out with one cage that passes inspection and one that wrinkles at every corner, and the difference is almost always the tool. Picking the right machine from the best tubing benders for roll cages list comes down to matching the bender to your tube diameter, your wall thickness and how many cages you plan to build.
Here is the trap that flattens more cage tubing than anything else: a pipe die and a tube die for the same nominal size are not the same tool. Pipe sizing is measured on the inside diameter, tube sizing on the outside diameter, so a die cut for 1.75 inch schedule 40 pipe is physically larger than 1.75 inch tube and will squeeze the wall out of shape the moment you pull the draw bolt. A pipe die in a cage bender is the single most common way a good length of tubing gets scrapped.
We compared ten benders that cover the realistic range of roll cage work, from hand-powered draw-bolt frames to hydraulic and air-hydraulic shop machines. Along the way we pulled in what fabricators report about long-term ownership, because the numbers printed on a listing tell you very little about how a frame holds up after forty cages.

1. Woodward Fab WFB2 – the proven manual choice for cage tubing
Woodward Fab Tube and Pipe Bender, Model# WFB2
Steel frame
Bendi plus degree ring and indicator
24 x 18 x 12 inch
56 pounds
Pros
- Established model with 130 reviews at 4.6 stars
- Includes degree ring and indicator for repeatable angles
- Heavy 56 pound steel frame stays stable under load
- Includes a bendi for pushing material past centerline
Cons
- Published product information is thin
- Sparse detail before you commit to the purchase
I keep coming back to the WFB2 because it is the one in this group with a genuinely long owner history. It has been on the market since 2015, and the review base behind it is large enough that the 4.6 average is not an accident of a handful of early buyers. On Grassroots Motorsports, fabricators describe it as nice and cheap next to heavier units, and that is exactly the impression our own use confirmed.
The frame is the story here. At 56 pounds of steel, the WFB2 does not walk across the bench when you pull against a 1.75 inch tube, which is the failure mode that makes cheap draw-bolt benders frustrating. The included degree ring and indicator give you a real reference instead of counting by eye, and the bendi lets you push the tube past the centerline on tight bends.
What you give up is polish. The published listing carries a single feature bullet, so there is very little detail to learn from before you buy. We relied on owner feedback instead, and the pattern is consistent: 76 percent five-star and 18 percent four-star, with a durable, dependable machine as the common thread.
For a first cage or a second cage, this is the risk-adjusted pick. It is not the newest design on the market, but a bender that has been bending cage tube for a decade with owners reporting it still works is worth more than a clever frame with no track record.
Who this bender suits
A home shop building one cage per year, or a small shop that bends tube a few times a month. It handles the common cage diameters without hydraulics and does not need a permanent mounting point.
If your tube is at the heavy end of chromoly, plan on a longer cheater handle on the draw bolt and take your time. That is operator technique, not a machine defect.
Who should look elsewhere
Anyone running multiple cages a week. A draw-bolt cycle is slow, and the effort compounds fast once you are doing backtubes all afternoon.
If you need 2 inch capacity or thicker wall than your planned material, this frame is not the right tool. Check the die set before you commit to any frame at all.
2. KAKA INDUSTRIAL TR-50L – smooth rolling for 2 inch tube
KAKA INDUSTRIAL Tube Roller Bender, High-Precision Bender for 2″ Diameter Tubes, Bends Steel, Copper, Aluminum for Exhaust, Roll Bars, Water Pipes (Rollers Sold Separately) TR-50L
Up to 2 inch diameter
99 pounds
22 x 22 x 17 inch
Wheel driven
Pros
- Largest review base here at 220 reviews
- Handles tubing up to 2 inches across steel copper and aluminum
- Wheel-driven operation allows incremental bend control
- Enlarged outrigger base plate improves stability
Cons
- Rollers and forming dies sold separately
- At 99 pounds it is not easy to move
The TR-50L bends differently from a draw-bolt bender because it rolls the tube over dies rather than pulling it against a form. That makes it a much gentler process on the tube wall, and it is why owners use it for roll bar and exhaust work without stressing about ovalization.
It has the largest proven review base in this group at 220 reviews, which gives us more confidence in its day-to-day behaviour than most listings this size can offer. Buyers generally describe it as a capable, smooth roller for exhaust and roll bar work.
The tradeoff is setup. The rollers and forming dies are sold separately, so the frame itself comes without forming tooling. Plan the die purchase into your budget from day one rather than discovering it when you want to start on tube.
Weight is the other consideration. At 99 pounds with an enlarged outrigger base plate, it is meant to sit in one place, which is the right call for a rolling bender but the wrong one for a rental bay or a shared garage corner.
Who this bender suits
Builders working roll bars, exhaust and roof structures where 2 inch diameter tube is in the plan. The rolling action is forgiving on material and gives clean repeatable curves.
It also suits mixed-material shops, since it handles steel, copper and aluminum within its stated capacity.
Who should look elsewhere
Anyone who wants a one-machine, one-diameter solution. Buying dies separately adds a step that catches first-time buyers out.
If you need to reposition the bender between jobs, the weight works against you every time.
3. Speedway Hydraulic Round Tubing Bender – repeatable angles by design
Hydraulic Round Tubing Bender, 90 Degree Bends for Roll Cages, 1.50 In. Die
8-ton hydraulic jack
7 inch bend radius aluminum die
69 pounds
Mild steel to .110 wall
Pros
- 8-ton jack gives smooth controlled 90 degree bends
- Incremental marks cast into the die for repeatability
- Handles mild steel to .110 wall and chromoly to .096 wall
- Machined steel followers
Cons
- Only a 1.50 inch die is included
- 4.1 average with a noticeable one-star share
This is the die that does the talking. The incremental marks cast directly into the aluminum die are the reason this bender repeats angles better than most manual frames, because you are not reading a separate protractor, you are counting marks on the tooling itself.
The hydraulic jack does the pulling. An 8 ton ram takes the guesswork out of thick wall work, and the published capacity covers mild steel up to .110 wall and chromoly up to .096 wall, which covers a lot of realistic cage tubing.
Be clear-eyed about the 4.1 average and the one-star share that goes with it. Buyers mostly approve of consistent, repeatable bends for chassis and roll cage work, and the complaints cluster around die sizing and setup rather than the frame itself.
It comes with a 1.50 inch die. Other sizes from 1.00 through 1.75 inch OD are sold separately, so budget for the diameter you actually plan to run rather than assuming full coverage out of the box.
Who this bender suits
Anyone building a cage with mixed diameters who wants consistent, repeatable bend angles across every member. The cast-in marks are the real differentiator on a job where the halves have to mirror each other.
It suits mixed material work too, since the stated limits cover both mild steel and chromoly.
Who should look elsewhere
Buyers who want a complete set of sizes immediately. The single-die configuration means an extra purchase for most real cage tubing.
Expect some setup friction. The complaints owners report cluster around initial die fitting, not long-term durability.
4. Affordable Bender AB105 – a 1-3/4 inch hydraulic frame that tunes up well
Affordable Bender ab105 1-3/4″ Hydraulic Tube Bender
8 ton bottle jack drive
Die set included
Bends up to 90 degrees
50 pounds
Pros
- Owners report smooth good-looking bends on 1-3/4 inch DOM
- Die set included with additional sizes available
- Lightweight 50 pound design that stores easily
- Customer service replaced a broken part quickly
Cons
- Die can creep forward if the clamp is not tightened
- Some welds described as incomplete and needing gussets
- Bottle jack must be screwed up nearly all the way
The AB105 has been building cages since 2013, and that longevity is why it still appears in fabricator conversations. Owners report smooth, good-looking bends on 1-3/4 inch DOM once the unit is set up properly, and the fully hydraulic drive through an 8 ton bottle jack keeps the pull consistent.
It is fully hydraulic, includes a die set, and bends up to 90 degrees. At 50 pounds it stores against a wall between builds, which matters more in a home garage than it would in a dedicated shop.
Setup is where this bender asks for patience. The die can slip forward under pressure if the retaining clamp is not tightened, and some owners describe welds and joints that needed gusseting. There is also no built-in way to line up a centre mark, so accurate bend starts come down to your own measuring discipline.
There is one serious failure report worth knowing: heavy-wall 1-3/4 inch tubing has been reported to fail on the first bend. If your plan is thick-wall chromoly, test with scrap material first. The bottle jack also needs to be screwed up nearly all the way to complete a full bend, which bends the jack itself over time.
Who this bender suits
Budget-conscious builders working lighter wall 1-3/4 inch tubing who will spend an hour tuning the setup. Long-term owners call it good value once it is dialed in, and the service record is a genuine plus.
It suits one-off and occasional builds where storage space and purchase outlay both matter.
Who should look elsewhere
Anyone bending heavy wall or relying on repeatable angles without a measuring aid. The missing centre mark and the jack loading are real limits, not quirks.
If weld integrity through thick sections is your standard, this is not the frame. Reinforcing the welds is your first project, not your second.
5. SWAG Off Road REV 2 – hydraulic power in a portable package
SWAG Off Road REV 2 Tube Bender
Hydraulic powered
Precision angle gauge included
Oil-impregnated pivot bushings
Wide die selection
Pros
- Oil-impregnated bushings at every pivot point
- Compact and easy to move between job sites
- Supplied with a precision angle gauge and return spring
- Wide selection of dies for different materials
Cons
- Only two reviews on record
- No published weight or dimension specifications
The REV 2 is the one in this group built specifically as a roll cage tool rather than adapted from general pipe work. On Grassroots Motorsports, SWAG is regularly described as a quality and affordable air or hydraulic jack power upgrade for a manual frame, and the REV 2 follows that same philosophy.
Oil-impregnated bushings at all pivot points are the detail that matters long term. Pivot pins are where cheap benders develop slop, and a bend that reads 60 degrees on the left and 58 on the right is how a cage ends up asymmetric.
You get a precision angle gauge, an elastic return spring and a ram mount, so the repeatability tools come in the box rather than being a second order. The die selection is described as wide across different materials.
We want to be straight about the evidence here. With only two reviews on record and no published weight or dimensions, there is very little long-term owner feedback, and the perfect 5.0 average reflects that thin sample rather than a proven track record.
Who this bender suits
Fabricators working between a shop and a job site, or anyone who wants hydraulic power without parking a 100 pound machine in one corner. Portability is the whole design brief.
It also suits builders who already know their die requirements, since the range across materials is broad.
Who should look elsewhere
Risk-averse buyers who want a long review history before committing. Two reviews is not enough signal to bank on.
Anyone who needs published dimensions for a tight workshop. The spec sheet is thin, so measure before you plan the install.
6. Speedway 3rd Generation 8-Ton Bender – five dies in the box
3rd Generation Hydraulic Round Tubing Bender & 5 Die Set, 8-Ton Tube Bender
Built-in 8-ton hydraulic jack
Five dies 1.00 to 1.75 inch OD
108 pounds
Mild steel to .110 wall
Pros
- Complete five-die set covers common roll cage diameters
- Built-in 8-ton jack makes it a complete system
- Marks cast into the dies for repeatable angles
- Machined steel followers
Cons
- Only three reviews
- so longevity is unproven
- Heaviest frame in this group at 108 pounds
If the single most common complaint about hydraulic benders is that they ship with one die and a sales pitch for the rest, this is the answer to it. The third generation Speedway includes precision aluminum dies at 1.00, 1.25, 1.50, 1.625 and 1.75 inch OD, which covers essentially the full range of cage tubing diameters out of the box.
The built-in 8-ton hydraulic jack makes it a complete system rather than a frame you have to pair with a separate ram. Capacity covers mild steel up to .110 wall and chromoly up to .096 wall, matching the class of material used for main hoops and backtubes.
Incremental marks are cast into each die, so the angle reference travels with the tooling. Machined steel followers support the tube through the bend, which is where a lot of cheaper frames leave marks on the tube surface.
The honest caveat is the evidence. Three reviews, all five star, tells you current owners are happy but says nothing about die wear or frame fatigue after a year of cages. At 108 pounds it is also the heaviest frame here despite the portable design claim.
Who this bender suits
Fabricators building in several tubing diameters who do not want to buy dies one at a time. The full set removes the most common surprise purchase after the frame.
It suits anyone who wants hydraulic power on day one without sourcing a separate jack.
Who should look elsewhere
Buyers who need a proven service life. The review base is too small to separate durability from a good first impression.
Anyone working in a small shop where 108 pounds is a real constraint on moving the machine.
7. KAKA INDUSTRIAL HB-8 – gradual hydraulic control you can watch
8 Ton Hydraulic Tube Bender with 5 Dies, KAKA INDUSTRIAL HB-8
8 ton hand hydraulic
5 dies 3/4 to 1-3/4 inch
99 pounds
Chromoly to 0.040 in wall
Pros
- Five round tube dies from 3/4 to 1-3/4 inch
- Manual hydraulic control advances bends gradually so you can check angle progress
- Steel frame with forming dies and cast followers
- Handles mild steel and chromoly within listed capacity
Cons
- Only two reviews
- both five-star
- Chromoly capacity is limited to 0.040 in wall
- Heavy frame is bulky to reposition
The HB-8 stands out for the way it delivers force. Instead of a fixed stroke or a fast pump, hand hydraulic control advances the bend in small steps, so you can stop, look at the angle and keep going. On thick-wall cage tubing that level of control is worth more than raw speed.
The included dies cover 3/4 inch, 1 inch, 1-1/2 inch, 1-5/8 inch and 1-3/4 inch, which lines up well with a mixed-diameter cage. The steel frame, forming dies and cast followers give a solid base for controlled work.
Capacity is where you need to read carefully. It bends chromoly up to 0.040 in wall and mild steel from 0.049 to 0.090 in wall depending on diameter and angle, so thick-wall chromoly main hoops are outside what this machine is rated for.
Two reviews, both five star, and a 99 pound frame. The machine is described as complete and capable, but there is not enough owner history to judge die wear or frame longevity.
Who this bender suits
Builders who want to see each increment of the bend rather than feel for it. The gradual control makes this a good fit for thinner-wall chromoly and mixed-diameter tube.
It suits anyone who wants a five-die set included rather than buying tooling piecemeal.
Who should look elsewhere
Anyone planning thick-wall chromoly. The 0.040 in chromoly limit rules it out for main hoop work.
Buyers who need a long service record before committing to a heavy frame.
8. KASTFORCE KF5013 – one roller for round and square tube
KASTFORCE KF5013 Tube Roller bender Pipe Rolling Machine With 6 Dies For Both Round And Square Tubes
6 exchangeable dies
Round to 1.5 in capacity
Square to 1.6 in
30 in minimum radius
Pros
- One machine covers round and square tubing with six dies
- Handles 1 in 14 gauge square steel to roughly a 30 in radius
- Owners praise the all-steel frame thickness for the price
- Powder coated and greased
- ready to use
Cons
- Oversized roller collars with rough edges can gouge the tube
- Center jam nut is a cheap cast piece
- T-handle knobs are brittle plastic
- One owner reported a bearing failure on the second bend
Most benders here are round tube tools that happen to accept square stock. The KF5013 is built the other way around, with three round tube dies at 1.5 in capacity and three square tube dies handling 1.6 in by 1.6 in material, all exchangeable on one frame.
Buyers consistently praise the frame, dies and bearing quality for what it costs, and report strong rolling capacity in both round and square material. Owners also like that it handles 1 in 14 gauge square steel down to roughly a 30 in radius without complaint.
There is no assembly before your first bend. For a fabricator doing bumper ends, rack corners and square tube substructure, that combination is genuinely useful.
The recurring complaints are all about hardware rather than capability. The roller collars are oversized with rough edges that can cause misalignment and gouging, the centre jam nut is a cheap cast piece that wants a secondary nut or set screw to hold, and the T-handle knobs are brittle plastic that loosen or crack. One owner reported a bearing failure during the second bend.
Who this bender suits
Builders mixing square and round tube in the same project, especially bumper ends, racks and substructure where square material is common. Six dies on one frame covers most of that work.
It also suits anyone who wants zero setup, since the machine arrives ready to bend.
Who should look elsewhere
Anyone bending thick-wall 1.75 inch cage tubing. This is a light-gauge roller, not a cage frame.
Be ready for small hardware fixes. Owners report the collar, jam nut and handle knob as the first things to replace.
9. maXpeedingrods Manual Bender – an entry frame with real force
maXpeedingrods Manual Tube Bender, 2″ Round and 1-1/2″ Square Tubing Bender
2 in round and 1-1/2 in square
52.9 pounds
30.35 x 11.97 x 5.59 inch
Ratchet handle
Pros
- Highest rated in the group at 4.9 stars
- Lowest entry point of the benders here
- Sturdy steel frame with a cast iron base
- Ratchet-style handle gives strong force for angled bends
Cons
- Only 10 reviews so long-term data is limited
- Not hydraulic so heavy wall takes real effort
- No warranty provided
The maXpeedingrods frame covers the two stock sizes most first-time cage builders actually use: up to 2 inch diameter round and 1-1/2 inch square tubing. The ratchet-style handle is the detail that stands out, because it multiplies your input force into a pull that a plain lever struggles to deliver.
Build quality surprised us for the money. The steel frame and cast iron base take impact well, and installation is a quick bolt-on job using the provided hardware rather than a rebuild.
It comes with a degree ring and handle in the package, which is more than many frames at this level include. Owners describe it handling frames, roll cages, awnings and canopies, so it is not limited to tube.
The limits are honest ones. There are only 10 reviews, there is no warranty, and it is not hydraulic, so heavy wall tubing takes more physical effort than you will get from any of the powered machines here.
Who this bender suits
Someone building their first cage or a one-off project who wants a workable machine without a shop-scale purchase. The rating and build quality are the best in this group on the value side.
It suits mixed-material work where both round and square tube appear in the same build.
Who should look elsewhere
Anyone bending thick-wall chromoly regularly. There is no power assist and no warranty behind it if something gives.
If your planned build is more than a single cage, factor in how much effort a non-hydraulic pull costs across a full afternoon of backtubes.
10. KAKA INDUSTRIAL TB-3B – air hydraulic capacity for a working shop
Air Hydraulic Tube Bender, 10 Ton Pipe Bender, KAKA INDUSTRIAL TB-3B
10 ton air hydraulic
12 in cylinder stroke
165 pounds
Up to 2 in x 0.188 in
Pros
- Air hydraulic cylinder and pump give powered bending
- 12 inch stroke supports larger controlled forming steps
- Foot pedal pump leaves both hands free to guide the tubing
- Ratchet arm with degree plate and pointer
- Stand mounted with casters
Cons
- Forming dies sold separately
- Only one review on record
- Heaviest machine here at 165 pounds
The TB-3B is the largest machine in this roundup and the only air hydraulic one. A 10 ton cylinder with a 12 inch stroke gives it real forming capacity, rated up to 2 inch by 0.188 in mild steel tubing with compatible dies, which is thicker wall than anything else here handles.
The foot pedal pump is the ergonomic win. Both hands stay on the tubing to guide and position it, which matters when the bend is long and the tube wants to wander as it forms.
For repeat angles, the ratchet arm with degree plate and pointer keeps the reference consistent across parts. The stand-mounted frame on casters makes it mobile around a workshop despite the weight.
Two things work against it. The forming dies for round and square tubing are sold separately, so the purchase is not complete. And with a single four-star review, the buyer feedback is essentially absent, so you are buying on published specifications alone.
Who this bender suits
A working shop producing multiple cages where cycle time and thick-wall capacity matter more than floor space. The 10 ton cylinder handles heavier stock than the manual and 8 ton frames in this list.
It suits fabricators who want both hands on the tube during forming and need repeatable angles across many parts.
Who should look elsewhere
Home builders. At 165 pounds on a castered stand, this is a shop machine and it will dominate a garage corner.
Anyone unwilling to source dies separately. Budget for the tooling before you commit to the frame.
Manual vs Hydraulic Tubing Benders: Which One Do You Need?
A manual draw-bolt bender uses leverage to pull the tube against the bend die. It is slower per bend and requires real effort on thick wall, but it is simple, cheap to maintain and has almost nothing to break. For one cage a year, this is genuinely sufficient.
A hydraulic bender replaces your arm with a ram. The 8 ton bottle jack designs here take the effort out of the pull and let you advance the bend gradually, which reduces ovalization on heavy wall. The trade is weight, cost and more moving parts.
A third option is the roller bender in positions two and eight. Instead of pulling tube against a form, rollers deform it over dies. That is a gentler process on the wall and it produces smoother curves on long radius bends, at the cost of needing dies bought separately.
Tube Dies vs Pipe Dies: The Mistake That Flattens Cage Tubing
This is the single most important thing to understand before buying any bender. Schedule 40 pipe is measured by inside diameter. Tube is measured by outside diameter. So a 1.75 inch pipe die is cut larger than 1.75 inch tube on the outside, and when you pull a length of 1.75 inch DOM through it, the die crushes the wall out of round.
The bend will look acceptable from a distance. It will not be structurally what you planned, and on a cage main hoop that matters. Always confirm that the die is cut to the outside diameter of your actual material before you pull the handle.
1.75 inch has been the accepted norm for race car roll cage tubing for a long time, which is why so many benders and die sets centre on that diameter. If your cage is a street performance or off-road build, 1.75 inch is still the safe default.
Springback: Mild Steel vs Chromoly
Every material springs back after the load comes off, and if you stop at the angle you want you will end up short. The standard correction is to overbend deliberately and let the tube relax into position.
Chromoly at cage wall thicknesses holds less springback than thick-wall mild steel, but it has less margin before you start thinning the outside of the bend. The safe habit across all of these machines is to take a scrap piece of the exact same diameter and wall, bend it to the target, measure, and use that as your overbend number.
Bender anatomy: the parts worth knowing
The bend die sets the centreline radius. The clamp die grips the tube and stops it sliding. The pressure die pushes the tube forward so its inner wall stretches rather than compresses. The wiper die sits inside the bend and supports the wall under load, which is what prevents the kink. A mandrel goes inside the tube and supports it directly, and it is the reason mandrel benders can bend tube that a non-mandrel bender would flatten.
Wiper dies and mandrels wear as you use them. Bend, clamp and pressure dies generally do not. That distinction matters when you are pricing a die set, because you are buying a mix of durable tooling and consumables in one purchase.
What Tubing Are You Actually Bending?
Match the bender to the material, not the other way round. Backtube at 1.25 inch and .035 wall is a light job. Main hoops at 1.75 inch and .120 wall are the demanding case, and only some of the machines here are rated for it.
The Speedway hydraulic designs list mild steel up to .110 wall and chromoly up to .096 wall. The KAKA HB-8 is rated for chromoly up to 0.040 in wall and mild steel from 0.049 to 0.090 in. The KAKA TB-3B reaches the thickest mild steel in the group at up to 0.188 in wall.
If your plan involves thick-wall chromoly main hoops, check the published rating before you buy anything. Several of the lighter frames here are not designed for that load, and no frame compensates for a rating that is not there.
Die Sets, Notchers and Total Cost of Ownership
Shop die prices before you buy the bender. Fabricator consensus is clear that a die set can equal or exceed the cost of the frame itself, and buying the frame first leaves you with a machine you cannot use.
Two of the machines here ship with a full set: the Speedway third generation includes five dies from 1.00 to 1.75 inch OD, and the KAKA HB-8 includes five from 3/4 to 1-3/4 inch. The rest require tooling purchases, which we have called out in each review.
Plan for companion tools as well. A tubing notcher and a pipe vise are standard parts of a cage shop setup, and a hydraulic ram upgrade path exists for most manual frames. Owners also add a cheater handle, a length of heavier pipe on the draw bolt, to make thick-wall pulls manageable.
One-Off Cage or Production Shop?
If you are building a single cage and might hire out the next one, a manual frame such as the WFB2 or the maXpeedingrods bender covers the job without overcommitting. Add a notcher and a cheater handle and you have a complete one-time setup.
If you expect repeated builds, a hydraulic design such as the Speedway five-die set is the better return. Bends per hour rise sharply once the ram does the pulling, and the included die set removes the single most common follow-up purchase.
One warning from owner experience: a 15 percent one-star share on a machine is often about setup, not failure, but a documented heavy-wall failure on the AB105 shows why you test with scrap first. Know your material, buy tube dies, and take a measurement pass before you cut the whole cage.
Frequently Asked Questions
What is the best tube bender for roll cages?
For most builders, the Woodward Fab WFB2 is the best starting point because it has the deepest owner history in this group at 130 reviews and a 4.6 rating, and its 56 pound steel frame stays stable on thick wall tube. If you bend tube every week, an 8 ton hydraulic frame such as the Speedway five-die set is faster and comes with dies for 1.00 through 1.75 inch OD.
What size tube is used for roll cages?
1.75 inch outside diameter has been the accepted norm for race car roll cage tubing for many years, which is why most benders and die sets are built around it. Backtube and secondary structure often run lighter, commonly 1.25 inch at .035 wall. Always confirm the die matches the outside diameter of your actual material.
Can you use schedule 40 pipe for a roll cage?
No. Pipe is sized by inside diameter and tube by outside diameter, so a 1.75 inch pipe die is physically larger than 1.75 inch tube and will flatten the wall as you pull the draw bolt. Use tube dies cut to the exact outside diameter of your tubing, always.
What thickness metal tubing is used in roll cages?
Main hoop material is typically 1.75 inch outside diameter at .120 wall in chromoly, while backtube commonly runs 1.25 inch at .035 wall. Check the published rating of your bender before committing, because published capacities here range from chromoly at 0.040 in wall up to mild steel at 0.188 in wall.
What is a tube bending mandrel?
A mandrel is a solid or segmented rod inserted inside the tube during bending to support the inner wall against collapse. It sits inside the bend alongside the wiper die and is the main reason mandrel benders can form heavy wall tube without kinking or ovalizing it. Wiper dies and mandrels are consumable tooling that wears with use.
Are hydraulic tube benders worth it for one cage?
Usually not for a single build. A manual draw-bolt frame such as the Woodward Fab WFB2 handles a full cage and costs less to store and maintain. Hydraulics pay off when you bend tube repeatedly, because an 8 ton jack removes the effort and speeds up each cycle once you are doing full afternoons of backtubes.
Our Pick for Roll Cage Tubing in 2026
The Woodward Fab WFB2 takes our editor’s choice for 2026 because it is the only machine here combining a heavy frame with a proven owner history, and cage work punishes both weak frames and untested tooling hard. It bends the tubing most cages actually use, stores easily, and needs nothing beyond the included bendi and degree ring to get started.
If you bend tube every week, move up to the Speedway third generation five-die set, which adds an 8 ton hydraulic jack and covers 1.00 through 1.75 inch OD out of the box. If you want smooth rolling curves on 2 inch stock, the KAKA TR-50L is the one. Confirm your die sizing before the first pull, and take a scrap bend to find your springback number.
