Your description is confusion, is it a tube bender which would OD dimensions or is a pipe bender which would be inside dimensions.
I'm interested in a tube bender mainly for bending 1" tubing which is which would 1" OD. I've read your answers so far and it still not clear.
The electric tube bender provides 5 sets of steel dies in multiple sizes: 5/8 inch (16mm), 3/4 inch (20mm), 1 inch (25mm), 1-1/4 inch (32mm), and 1-1/2 inch (38mm).
