135° Split point is self-centering for reduced thrust and easier penetration. Manufactured from high-speed steel substrate with heavy duty geometry. Black and gold (Barber pole) oxide finish for less galling. Three flats on shank for sizes above 11/64" for tighter chucking and less slippage. For superior rigidity in maintenance applications in low to medium carbon steel, alloy steel and cast iron. 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 ...

Applications: Used to enlarge existing holes Features: Standard 3 flute design Right hand (clockwise rotation) cutting direction Since chip loads are spread over a greater number of cutting edges, reduce regular drill speed 25% and double feed rate Normal spiral - helical flutes Standard shanks that correspond to the drill diameter Normal length drills have flutes proportional to length
