SWAG HULK Tubing Roller
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".

The machine sells for $899.95. 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.

Well built

I always wanted a tube roller for other projects other than signs but do need it for the industry occasionally. I look forward to retro fitting the pipe threader when I get time. Glad to have come across this.


We are very glad to hear that you are satisfied with your Hulk!

Don't hesitate to reach out to us directly if any questions come up regarding its use or setup.

Thank you,

Outstanding Product!

I’ve never rolled any steel at all prior to owning the Hulk. My first project was a set of 12’ arched gates for a client. Using the Hulk, with zero prior experience, I was able to achieve a high level of symmetry, which can only be attributed to these features: ZERO slop in the roller, and the digital read out.

The gate client (photo) has a background in large scale fabrication/manufacturing, and he was truly impressed with the outcome.

I can only imagine how much better my future projects will be after some more experience with the tool.

The Hulk has helped open my business to more opportunities in the custom fabrication market, and has more than paid for itself on the first use. Combine the quality of the roller with the massive catalog of available dies, there’s no project that my shop can’t tackle.

So glad I found you guys. I have been looking for a well built tubing bender for my home shop. I came across the Hulk while searching. Purchased the Hulk and had it in 2 days. Very impressed with the design and attention to detail. Customer service and communication was awesome as well. Can’t wait to knock out a few projects! Best of all, MADE IN THE USA!

Small business start up

I bought this to build a custom garden arch for one of my clients and I am very pleased with how easy it is to replicate rolled tube. I have now made 8 of the same arch with only one small hiccup. I couldn't figure out why the square tube would roll to one side and quickly figured out that it matters where you put the weld seam so it was my own error. Thanks swag for an amazing product that has paid for itself a few times over!


Wow!!!! This roller is amazing quality! I was just going to upgrade a harbor freight roller to save some money, but as a machinist I looked at the harbor freight roller and the build quality is mediocre at best. There is so much slop in the sliding mechanism that getting repeatability on your bends would be very difficult without putting a lot of work into tightening up the tolerances. Save yourself a bunch of time and frustration right from the beginning with this roller. It is incredibly built with tight tolerances and beautiful attention to detail all the way around! These guys obviously care about their products and quality and I can assure you I will be doing more business with this company!
