REDUCED SHANK 190 47/64

Description:

Reduced Shank drill bits are larger sized general-purpose drills manufactured from premium high-speed steel. Has a round shank or shank with three flats for a more positive grip in the drill chuck - flats reduce drill slippage under high load. Standardized lengths result in minimal adjustment during tool changes in screw machines and machining centers. Best used in applications for portable drilling due to increased rigidity, less deflection, and better hole accuracy. Use on carbon steel, cast iron, alloy steel, wood, and wherever maximum chuck capacity is 1/2 ". Comes with black oxide surface finish that increases wear resistance and adds lubricity, improving chip flow.
