High Speed Steel
Type 278

This general purpose 118° point H.S.S. drill is designed for use in portable air or electric drilling equipment with 3/8" chucks.
Note: Surface treated flutes on sizes larger than 1/2" diameter.

Special Hi-Molybdenum Tool Steel
Type 278-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 steel and other hard metal drilling applications.
