Series 157 General Purpose Screw Machine Drills

Series 157 drills were developed for use in screw machines of all types, and all conditions which require the use of short drills. The drills are made with short flutes and short overall length to obtain maximum rigidity without sacrificing any of the cutting ability. This type of construction gives these drill many applications, not only in screw machine work, but in portable drilling, sheet metal, and body work.
