Norseman Jobber Length Drill Bits - Type 190-AG Letter

Norseman Jobber Length Drill Bits - Type 190 - AG Fractional

Magnum Super Premium - Special Hi-Molybedenum tool steel. 135 degrees 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 degrees F and then nitro-carburize finished at 950 degrees 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. Sizes smaller than #52 have non-split points.
