These 1/2" Round Tubing dies are made from high impact industrial Delrin, which will not scratch your aluminum or stainless steel tubing. Each die is precision grooved to capture the tubing to help prevent distortion. They work with the Mighty Mite and the Pro 2 Bender (conversion kit or conversion bushings are needed for the Pro 2 to accept these dies.)
These round tubing dies are also available in 3/8" sizing.
