Norseman SP-13M Jobber Length 13 Piece Metric Drill Bit Set 49042

Magnum Super Premium Jobber Length Drill Bit Set

Type 170-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 use in work hardening grades of stainless steel and other hard metal drilling applications.

Set includes 1.0mm - 7.0mm by .5mm. Organized in a Indexed Metal Case.
