Chicago-Latrobe Reduced Shank Drill Bit, 21/32 in, 118 , Cobalt, Tin Model: 53642 GN_GY6VY577

Product details:

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. TiN (Titanium Nitride) coating adds lubricity and hardness, enhancing chip flow, finish hole quality and drill life. Use wherever maximum chuck capacity is 1/2". For drilling in carbon steel, allow steel and cast iron. Made In USA.
