Chicago-Latrobe 157 3/8 HSS General Purpose Bright 118 Point Screw Machine Drill - Pkg Qty 6

135° split point for faster easier drill penetration. Manufactured from high-speed steel substrate with heavy duty geometry. Short flutes for rigid strong tools. Black oxide finish for increased lubricity with reduced galling and welding. Superior rigidity in hand or machine operations. For drilling in alloy steel, stainless, cast iron and tool steel. Made In USA. Pack Of 12. 30 Day Warranty.

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 ...

Heavy duty geometry for drilling tougher materials by hand or machine. Shorter flutes and overall length provide superior rigidity to minimize deflection when using heavy feed rates. Manufactured from premium cobalt high-speed steel. 135° split point is self-centering for reduced thrust and easier penetration, sizes under .0625 do not have split. Straw oxide finish for increased lubricity with reduced galling and welding and easy identification of cobalt. For drilling in alloy and carbon steel, stainless, cast iron and tool steel. Made In USA. Pack Of 12. 30 Day Warranty.

Large size general-purpose drills with round 1/2" reduced shank. Manufactured from high-speed steel substrate. 118° radial point. 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. Ideal for portable drilling due to increased rigidity. Black oxide finish increases wear resistance and adds lubricity, improving chip flow. Use wherever maximum chuck capacity is 1/2". For drilling in carbon steel, allow steel, ...
