29pc. High Speed Steel Drill Set
Special Hi-Molybdenum tool steel, 135° 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°F and then nitro-carburized 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 othe hard metal drilling applications. Made in U.S.A. Set includes 1/16 - 1/2 by 64ths.
