The HULK is 100% designed, machined, formed, manufactured & assembled in the USA.
Weighing in at 80 pounds, this machine is a real beast! With 4340 Chromoly axles, fully machined drive yoke, and powered by a two-ton bottle jack, there isn’t much that the Hulk roller can’t handle.
We currently offer 76 different die sizes profiled for round tube, round pipe, and square tube. We also have a full line of unique dies for rolling flat bar, handrail cap, rectangular tubing, and square tubing in a diamond profile. Most of our dies are also available in Delrin which is well suited for rolling anodized aluminum, copper, brass, and chrome finishes where abrasion or scratches on the material surface are not acceptable. The center drive dies are fully keyed to the drive axle to ensures smooth operation and a solid connection.
If you have any experience rolling tubing, you know that most machines have a few main issues; the material twisting as it is rolled and how difficult it is to make repeatable bends. We have addressed the first issue by implementing several key design features. The 4340 chromoly non-drive axles are machined down to a tolerance of +/-.003” and two adjustable shaft collars on each axle are used to keep the dies perfectly centered between the ¼” thick steel frame plates. This prevents any side-to-side play that can cause the material to corkscrew as it is rolled.
The second major cause of material twisting as it is rolled is play in the center drive yoke. There are several large radius rollers on the market that use a cast steel yoke or a formed piece of steel to hold the center drive roller in place. Unfortunately, cast and formed parts will never be perfectly square or straight. When the center yoke is not square, the drive die tends to contact the material you are rolling with uneven pressure, pushing your material to one side, and causing it to twist. The center drive yoke on the HULK is made of 3 pieces of ¾” thick steel which have been fully machined and bolted together to ensure a perfectly flat and square yoke. This means the downward force that the drive die exerts on the material is always straight down, thus preventing any twisting and helping to prevent irregular material deformation.
Another often overlooked issue many people experience when rolling tube is the challenge of creating repeatable radius bends. The HULK includes a high-quality digital read out height gauge that measures downward travel of the center drive die, making it easier to create the same arc over and over. To use the DRO, place your material in the roller then “zero” the height gauge when the drive die is barely touching the material. Roll one piece of material to the desired radius and record the location of the outer dies as well as the measurement displayed on the digital read out. If you need to create the same part in the future from the same material, just put the non-drive dies in the same location and roll until the DRO gives you the correct measurement. Easy!
Most rollers on the market use a large top-screw to apply downward pressure on the material and cause it to form a radius. Tightening the top screw can be quite difficult when working with thick-walled material or square tubing in general. The HULK uses a 2-ton bottle jack. This makes applying smooth, consistent downward force much easier. The 2-ton bottle jack is bolted to the top of the drive yoke to prevent any movement while under load and ensure it is always perfectly centered over your material.
To ensure smooth operation, all of the dies ride on high-quality roller bearing. The 3-way adjustable manual handle can be unbolted and replaced with an electric pipe threader that is available from Harbor Freight. Their pipe threader (item #62203) is an easy, simple to install add on that will take the cumbersome and tedious chore of rolling thick-walled tubing and turn it into an almost completely hands-free operation.
With its powder coated steel frame, internally threaded aluminum spacers, green powder coated handle and stainless-steel fasteners, this tubing roller is designed to look as good as it performs. The HULK is sold as shown above, except for the sheet metal base structure which is not included. It comes 90% assembled.
The (4) 3/8" bottom mounting hole locations are 29" x 7.625" on center. The total footprint of the base plate is 30" x 8.625".
Dies can be purchased using the list above or by themselves. Each die size includes one drive roller and two non-drive rollers. You will not need a replacement drive axle since one comes with the tubing roller by default. We have over 1000 die sets on the shelf and 99.9% of the time we have every die size in stock.Related Products

Customer Reviews
We are rolling C3x5 legs up on the 3" flat dies. The channel just fits. The Hulk got us out of a supplier lead time pinch. After 1200 feet of channel, the drive die is taking a beating as its set screw holes are in line with the legs which was causing the die to gall and mushroom. We relieved the die edges, packed the sides with grease, and we were back to rolling. We also are able to get better channel utilization since the tangents are smaller on the Hulk than what our supplier was requiring.
I bought this with an expectation that our guys would have this destroyed after rushing to get through our production run. Not the case at all. It was destroying our guys. We don't have any 18 year olds to Tom Sawyer into turning the crank so we added the HF threader. The only minor annoyance is the retraction springs on the Hulk are not enough to pull and hold the weight of the threader when it gets bumped loading/unloading a new stick.
Excellent machine. Stout, compact, user friendly. Can be taken to job site if necessary.
Adds a new dimension to my work process.
Above all…SUPER CUSTOMER SERVICE!!!
Best roller we've ever used! The digital readout makes repeat bends a breeze. I mounted a Ridgid 700 power pipe threader for effortless rolling. Makes me want to go after curved railing jobs more often. The guys at SWAG are super helpful and go out of their way to get their products delivered quickly.
We worked five days with seven, yes seven, other benders and methods ranging from heat, to thin-strip laminations, to hossfeld type benders. Nothing was working and we had just about decided to change to a fiberglass molded part when I saw a review online for the SWAG off-road HULK roller. I told the guys we would work on other projects while we waited for the HULK to arrive.
Called SWAG, talked with Dave who even helped us pick out the right die set, and a few days later we had everything.
Assembly was easy, although we could have done better if we had ball-head Allen wrenches. We do now, of course.
It took us one test piece of material to know we had found the right machine. We had 30 hours and lots of wasted materials in failed attempts. With the HULK, we made eight of the 16 curves needed in the first hour.
Then we figured out our shop ceiling was too low to roll the large curves with the machine on the bench.
Called Dave, and again he had the right answer for us - it is okay to lay the HULK on its side, and with that done we finished the rest of the bends that afternoon.
Welded everything the next day.
The pieces were so accurate with the DRO that we only had to use one welding jig with no changes to lay out two lefts and two rights (One up one down for mirror sides).
These curves used 8, 10, 11, and 14 foot stock, with about 4 inches of feed in and out scraps. Here are some pics. Each unit is 17 tall and 13 wide. Huge curves we would never have made right without the HULK.
Already booked another project and instead of dreading the curves with the old methods, we are looking forward to the project now that we have the HULK!
Smoothest crowner on the market. Well built. Accurate digital readout.
