Chicago-Latrobe 190C 21/32 General Purpose Straw 118 Silver & Deming Drill with 1/2 Reduced Shank

Large size general-purpose drills with three-flatted 1/2" reduced shank. Manufactured from premium cobalt high-speed steel. 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. Straw oxide finish increases wear resistance, adds lubricity, improving chip flow and easily identifies cobalt drills. Use wherever maximum chuck capacity is 1/2". For drilling in carbon steel, allow steel and cast iron. Made In USA. 30 Day Warranty.
