- Patented micro-groove cutting edge and spurs produce a smoother hole finish
- Double spur design scribes the hole before the chips are made, producing a cleaner hole and reducing vibration
- Shorter bit length gets into confined spaces (between studs) where standard lengths will not fit
- All bits have a 1/4" hex shank that fit all drills and 1/4" quick change adapters
