Restrictions green


Use for:

  • Rolling / bending metal tube (measured by outside diameter).
  • Equipped with .5 inch, .75 inch, 1 inch, and 1.25 inch diameter die sets.
  • Thin-wall tube is this machine’s forte.

Do Not Use for:

  • Wrong tube sizes with a given die set. Die sets are specific to tube size.
  • Do not use for pipe. Tube is sized by outside diameter, pipe by its theoretical inside diameter.

Hazard Analysis

  • Eye protection required. (Metal can snap while bending, and flakes of rust, mill scale, or paint can become airborne.
  • Cuts / Scrapes from sharp cut edges of workpiece. Use of gloves is acceptable when using this machine.
  • Cuts / Scrapes / bruises or worse if care is not taken to prevent metal stock from slipping during the bending process, possibly becoming airborne due to high pressure.
  • Pinched fingers or skin.
Warning Safety glasses Eye protection required!


Notes and Best Practices

The tube bender with foot pedal.
  • Die Set consists of 3 Parts:

- One Forming Die

- One Pressure Die (Follow Bar)

- One U-Block (A small square block that retains the workpiece.)

  • The Forming Die does not rotate. The Follow Bar rolls around the die. A stationary die makes it easier to control the location of the bend your workpiece.
  • Our machine is equipped with a foot pedal control. (The manufacturer’s instructions and the YouTube instructions show a hand control.)
