Electrical supply houses, the ones you get the emt from have benders. I don't know about the radius.
Most benders need a die for the specific size material and the specific size bend your doing. A little practice is needed due to spring back, etc. There has been talk about making wooden dies for short runs (small amounts) of bends.
If you know a machinist, making the dies should not be a problem (hint - hint)
