Norseman 190-AG Magnum Super Premium Jobber Length Drill Bit 13/32
Special Hi-Molybdenum tool steel. 135 Deg 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 Deg and then nitro-carburize finished at 950 Deg to be measurably harder than high-speed steel. Space age nitro-carburized steel withstands substantially higher drilling temperatures while maintaning 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. Learn More$4.90 As low as: $4.79Out of stock
