Screw machine drills (also know as stub or stubby drills) are manufactured to National Aerospace Standard 907. Sizes smaller than 1/16 and #52 have the 118 degree standard point. Ideal for portable or machine drilling. Short, rugged construction performs well in a broad range of materials. The 135 degree split point is self-centering and reduces thrust. They are often used in screw machine setup where spindle clearance is limited. Screw machine drills are popular in the automotive and construction industries.
