Questions about this product
- What does this countersink bit do in one pass?
- It drills the pilot hole and cuts the countersink recess at the same time. That lets a screw head sit flush or just below the wood surface. The result is a clean, hidden screw hole for furniture and cabinet work.
- Will the hex shank fit my regular drill?
- Yes, the hexagonal shank grips standard drill chucks and quick-change holders. The hex shape stops the bit spinning or slipping under load. That means steady power transfer and cleaner holes.
- Is this bit only for wood, or harder stuff too?
- The double-edged geometry is tuned for wood and wood composites, where it cuts fast and clean. It's made for joinery, trim, decking, and cabinetry. It isn't designed for metal or masonry.
