Technical Features
- Four-bit sizing set — #6 (3/32 in.), #8 (7/64 in.), #10 (1/8 in.), #12 (5/32 in.): Covers the most common screw sizes used in hinge and hardware installation, reducing the need for multiple separate purchases.
- Self-centering design: Automatically locates the center of hinge and hardware mounting holes, eliminating manual measuring and reducing the risk of off-center pilot holes.
- 1/4 in. hex shank: Compatible with standard hex chuck drills and quick-change bit holders for fast, tool-free bit swaps on the job site.
- 4 in. bit length: Provides adequate reach for recessed or obstructed mounting points while maintaining rigidity during drilling.
- Steel construction: Delivers durability suitable for repeated use in wood and similar materials encountered in hardware installation tasks.
- Non-impact-rated: Intended for use with standard drills only — not for use with impact drivers.
Applications
- Drilling centered pilot holes for door and cabinet hinges
- Pilot hole installation for hooks and surface-mounted hardware
