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 used 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.
