Screw Machine Length Drill Bits Cobalt Steel HD Split Point

Screw Machine Length Drill Bits
The shorter flute and overall length increase the rigidity, resulting in less deflection, better hole accuracy, and longer tool life. Sizes smaller than 1/16 and larger than 1/2 have the 118º standard point.

Choose a subcategory or select from the part list below
Cobalt Steel, HD Split Point
Manufactured to National Aerospace Standard 907. Made of heat resistant cobalt. 135° split point is self-centering and reduces thrust. Ideal for portable or machine drilling. Short, rugged construction performs well in a broad range of materials in the iron and steel families. Screw machine drills are popular in the automotive and construction industries. They are often used in screw machine setup where spindle clearance is limited. Sizes smaller than 1/16" have the 118° standard point.
High Speed Steel (HSS), HD Split Point
