I offer a handled round punch and a hand held round drift. The handled punch is made from 3&1/2" long 3/4" diameter stock and tapers to 1/4". The hand held drift is made from 9" long 1&1/8" diameter stock and tapers to 3/8". I use H13 steel for these tools. This steel has the right combination of toughness and hardness at high heat. And, I have these tools machined. This is practical since the properties of this steel that make it so good for hot use also make it very difficult to hand hammer.
