Norseman RSP-29 Jobber Length Reduced Shank 29 Piece Drill Bit Set 92100

Magnum Super Premium Jobber Length Reduced Shank Drill Bit Set

Type 128-AG NAS 907B 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 a 3/8" reduced 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 use in work hardening grades of stainless steel and other hard metal drilling applications.

Set includes 1/16" thru 1/2" by 64ths. Organized in an Indexed Metal Case.
