Multisize Tube Benders for Soft Metal


180° Maximum Bending Angle	90° Maximum Bending Angle	120° Maximum Bending Angle

Bend more than one size of tubing without adjusting the bending head. All-aluminum benders are lightweight and well suited for smaller tubing. Benders with steel construction provide the rigidity and leverage needed to bend larger, stiffer tubing without flexing.

1" Bend Radius—Copper must be annealed before bending.

Tube Benders

Smoothly bend hard metal tubes, such as steel and titanium, without causing crimps or kinks. Unlike other tube benders that have aluminum mandrels, these tube benders have durable steel mandrels to withstand repeated use with hard metal as well as soft. Long handles create extra leverage to bend hard metal with less force. In addition to making bends as small as 15°, these benders have a rotating handle to make bends from 90° to 180° without ever crossing handles.
