Good quality HREW tubing bends nearly the exact same as 1020 DOM. There are too many alloys and qualities of HREW being produced, and it gets mixed with and sold as other inferior tube products (at times). *1) We do not gurantee performance on HREW. To avoid this, bend a thicker wall than the absolute minimum for a die, and bend on the largest CLR you can. Meaning that the bends may appear flat on the outside of the bend.

NOTE: If you bend the thinnest material you can on ANY die, you will get the most deformation possible on that die. M605(*3) To protect the pins in the machine, you will need to upgrade your M601 to an M605 to bend this size (by purchasing an HD kit, they are under $100 and sold with the tubing benders in our store). It will drastically reduce your bend quality. 134' wall (or thinner, PLEASE do not use the back pressure die location (labeled HD only on the stickers). Keep in mind you will have to use (2) pressure dies whenever you get to. If you are required to use 2 pressure dies, the material must be in contact with both, so plan your cut lengths and bending accordingly. *2) This capacity assumes 2 (TWO) pressure dies are in use, per the machine's operation instructions. Ratings on aluminum (especially anything in a T6 temper) are based on our testing, read notes below on aluminum ratings. *1) We do not guarantee performance on HREW. Please e mail us with your questions!Ĭarbon Steel (1020 DOM, HREW(*1), ERW, 4130 Chromoly, etc) We will continue to do testing and add the new dies we’re designing for the machine as we discover new lower limits to minimum bend radii. NOTE – With the recent release of our affordable and high-performance mandrel conversion, we have not yet tested all dies to the limit in terms of minimum wall thickness. The solutions to these issues are usually easy. The culprit is usually setup, material quality, or lubrication. If your tubing bender does not perform to the limits shown in this chart, please call so we can help diagnose the problem. If you want to know what to expect from a specific material, we offer bending diagnostic services. Although the chart below is the result of tests we performed on purchased materials, we cannot guarantee that you will achieve the same results due to the wide variation in material quality from one mill to another.

We do out part to ensure that your fab shop runs as smoothly as possible. Rogue Fabrication we work hard to provide our customers with the most complete and accurate tube bending information available.
