Cle-Line 1896 27/64 HSS Heavy-Duty Steam Oxide 135 Split Point Screw Machine Drill - Pkg Qty 6

Large size general-purpose drills with three-flatted 1/2" reduced shank. Manufactured from high-speed steel substrate. 118° split point for easier, more precise penetration. Standard 6" overall length and 3-1/8" flute length for increased rigidity, less deflection and better hole accuracy. Standardized lengths result in minimal adjustment during tool changes in screw machines and machining centers. Three flats on shank for a more positive grip in the drill chuck; flats reduce drill slippage under high loads. Ideal for portable drilling due to increased rigidity. Black and gold ...
