'''[[High speed steel]]''' (HSS) is a form of [[tool steel]] where the bits are much more resistant to the effect of heat. They can be used to drill in metal, hardwood, and most other materials at greater cutting speeds than carbon steel bits and have largely replaced them in commercial applications. | '''[[High speed steel]]''' (HSS) is a form of [[tool steel]] where the bits are much more resistant to the effect of heat.

'''[[Cobalt]] steel''' alloys are variations on high speed steel which have more cobalt in them. Their main advantage is that they hold their hardness at much higher temperatures, so they are used to drill | '''[[Cobalt]] steel''' alloys are variations on high speed steel which have more cobalt in them. Their main advantage is that they hold their hardness at much higher temperatures, so they are used to drill stainless steel and other hard materials. The main disadvantage of cobalt steels is that they are more brittle than standard HSS. | ||
