- 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
