Tool Bits, M2 High Speed Steel, Individual Sizes
- 2-1/2" long M2 HSS tool bits
M2 is a high speed steel in the tungsten-molybdenum series. The carbides in it are small and evenly distributed. It has high wear resistance. It is used for a variety of tools, such as drill bits, taps and reamers.
Chris' Tips
We carry both imported tool bits made of M2 high speed steel and American-made tool bits made of T-15 high speed steel from the A. R. Warner Co.These tool bits are accurately ground on four sides and can be used as inexpensive parallels to support work on the mini mill or surface plate.AISI M-2 is an all-purpose grade with notable toughness. Good wear resistance and hot hardness qualities.
