Bending Dies and Backshoes for BendPak® Machines
BendPak Bending Dies and Backshoes For Your BendPak® Machine
Huth has made bending dies and backshoes tooling for BendPak® machines for a long time… since their customers insisted on it! Huth tooling is machined in America to specific tolerances from solid steel. After it is machined, it is gas-carburized and oil quenched to a minimum hardness of 58 Rockwell “C” scale. All Huth tooling is readily available from shelf stock. However, Huth will manufacture custom tooling to your specifications for sizes not listed in this schedule.

BendPak Direct Fit 3" Bending Dies
DIRECT FIT 3″ BENDING DIE
The reason Huth is known for superior bending is our superior tooling design, especially in the critical bending cavity.
This quick video can help you understand…
Great bends on 3” OD tubing was the big thing BendPak® users needed from Huth, and we developed 3” tubing dies that fit directly on BendPak® benders.
These fit the current version of BendPak® bending machines that have been in the market since the early 2000’s.

Back shoes- 2 required
Huth round tube Back shoes work very well on both new and old style BendPak® bending machines. For older style (no pins on backshoe holder), use Huth die pins. For newer style, simply use the backshoes without pins … the pins on the backshoe holders slide easily into the holes provided for the pins.
