Norseman SP-29P Ultra-Dex 29 Piece Jobber Length Drill Bit Set

Magnum Super Premium Jobber Length Drill Bit Set

Type 190-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.

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 1/16" thru 1/2" by 64ths. Organized in a Black Ultra-Dex Case.
