Grizzly Industrial, sells a set that goes from 1/4 " to 1" in fine and coarse. It also is made of high speed steel, and is one Hell of a bargain when compared to the prices that are charged for carbon steel sets. The Grizzly set is 45 piece HSS. tap and die set model G 9770 $239.95 . I have used this set for many years at work and at home and have had no problems of any kind, and would recommend this set to anybody. Ken.
