Tapered Pilot Holes for wood screws are recommended especially for hardwoods. The hole in the first piece of wood is drilled large enough to accommodate the screw shank. In the second piece of wood, the hole is perfectly tapered to fit the screw thread.
Features
- Tapered drill bits are milled from solid High Speed Steel for long life.
- Highly polished flute surfaces for easy chip ejection.
- Cutting edges have back relief for smooth drilling with less friction.
- Special tip grinding for precise centering and penetration.
