COBALT JOBBERS LENGTH DRILLS 135° SPLIT POINT

DWDCO Series - m35 Cobalt D/ACO Series - m42 Cobalt

Manufactured to National Aerospace standard 907. Made of heat resistant cobalt, they display higher red hardness which permits speeds upto 30% greater than high speed steel drills and are especially effective in drilling tough, high tensile strength materials like PH stainless steel, inconel, and titanium. The 135° split point is self-centering and reduces thrust. Sizes smaller than 1/16” have the 118° standard point.
