[QUOTE="Trickymissfit, post: 875230, member: 25383"] high speed steel, refers to a completely different class of steel than we would normally be thinking of. It hardens a few points harder, and heat treats differently. High speed steel is what most drill bits are made of, as well as most reamers and end mills. What particular type is in vogue right now I can't say, but some common ones are Rex M2, Rex 95, Gorham Cobalt, Speed Star. Vasco Supreme is about as hard of a high speed steel as I've ever seen, and also the most expensive. A high speed reamer often will cut better than a carbide one, but will need resharpening a little more often. gary [/QUOTE]
