29 pieces. 3-Flats on shank. Fractional. 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-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. Especially designed for hand held drills. In a molded weather tight, impact resistant Ultra Dex case with a belt clip. Type 178-AG, Manufactured to NAS 907B specification. Made in USA.
