General purpose 118 degree point, high-speed steel drills perform well in a wide variety of ferrous metal drill applications.  The black surface treatment prevents chip welding and increases abrasion resistance.

Ultra Cut Super Premium drills are special Hi-Molybdenum tool steel, 135 degree split point for fast penetration and accurate starting without a 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. Drills are heat treated at 2185 degrees F and then nitro-carburize finished at 950 degrees F to be measurably harder than high-speed steel.  Space age nitro-carburized steel withstands substantially higher drilling terperatures while maintaining sharpness. 

Recommended for use in work hardening grades of stainless steel and other hard metal drilling applications. Sizes smaller than #52 have non-split points.
