<strong>Description</strong><br /><br /> All BendPak tooling is precision machined from solid steel. After the CNC machining process, the tooling is gas carburized, oil quenched and heat treated to a minimum hardness of 58 Rockwell. No cast or ductile (brittle) iron is used for any of our tooling. All BendPak benders are built with 3” bending capacity so you can order three inch dies when you need them. No other manufacturer uses our exclusive step-cut process for the die rails that actually helps contain the larger size tubing better and gives you a more uniform bend. <br />
