Here is a range of drill bits made with High Speed Steel (HSS). This range includes bits for producing counterbores and countersinks, as well as plugmakers, Forstner bits, twist drills, and pocket hole bits. High speed steel (HSS) is a form of tool steel that’s commonly used for producing various cutting and drilling tools. HSS bits are hard and much more resistant to heat than materials such as high carbon steel. They can be used with various materials such as hardwood and metal. They can be used at greater cutting speeds than carbon steel bits, and have largely replaced carbon steels in general tool manufacturing.
