7/16 SQUARE COBALT TOOL BIT7/16 SQUARE COBALT TOOL BIT 5-092-028, IMPORT, COBALT, 3-1/2" OAL Our High Speed Steel tool bits are available in a M2 steel for general purpose machining in mild steels, alloys and tool steels. They have good heat and abrasion resistant properties and are best used when making an interrupted cut or where the tool may be subject to a heavy load or shock! We also stock a Cobalt version for heavy duty machining of the same materials. The cobalt content increases those heat & abrasion resistant properties for longer tool life vs. the standard M2 bits. Resharpen on a standard bench grinder, just make sure you have relief on the tools so it does not "drag" on your work piece when turning. They can also be ground to special form's or radius's for those special jobs!
