High Speed Steel
Type 280

This general purpose 118° point H.S.S. drill is recommended for use in portable air and electric drilling equipment with 1/2" chucks. Type 280 drills may be used in power applications such as drill presses where a short rigid drill is required.

Super High Speed Cobalt
Type 280-D

Heavy duty 135° split point with gold finish for use in drilling hard tough metals, free machining stainless steel, high temperature alloys, titanium and certain plastics. High red hardness of cobalt steel permits speeds 30% higher than regular high speed steel drills. Cobalt drills require rigidly held positive feed drilling equipment. Sizes larger than 3/4" have 118° split points.

Special Hi-Molybdenum Tool Steel
Type 280-UB

135° split point for fast penetration and accurate starting without center punch. Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance. Body and clearance are gold surface treated for maximum lubricity. Heat treated at 2185° F and then nitro-carburize finished at 950° F to be measurably harder than high speed steel. Space age nitro-carburized steel withstands substantially higher drilling temperatures while maintaining sharpness. Recommended for use in work hardening grades of stainless stell and other hard metal drilling applications. 3 flats on shanks. Sizes larger than 1" diameter have 118° split point.

All drills are 6" OAL
