About Shars Center Drill & Countersink Bit Tooling Set
Body Dia: 1/8, 3/16, 1/4, 5/16, 7/16". Drill Dia: 1/32, 3/64, 5/64, 7/64, 1/8, 3/16". M42 cobalt material provides better wear resistance than HSS material on harder workpiece material such as high tensile alloys, inconel, and high nickel stainless steel. Plain style 60° angle used for producing center holes in workpieces which require precision drilling or machining between centers. Also used as starter holes to prevent a drill bit from "walking".
