  • Features
Larger size general purpose drills with 1/2 in reduced shank
Round shank or shank with three flats for a more positive grip in the drill chuck, flats reduce drill slippage under high load
Standard overall length and 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
Black oxide surface finish increases wear resistance and adds lubricity, improving chip flow
For portable drilling due to increased rigidity
