Magnum Super Premium Silver and Deming Drill Bit Set
Type 130-AG
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, with 3-flats on a 1/2" shank.
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 us in work hardening grades of stainless steel and other hard metal drilling applications.
Set includes 9/16", 5/8", 3/4" and 1".
