Engineered for precision boring, this 6-55mm woodworking spade drill bit set delivers clean, flat-bottomed holes in a single pass. The high-carbon steel construction ensures exceptional durability and edge retention, while the extended 6-inch shaft provides the reach needed for deep mortising and through-hole applications in timber and engineered wood. Features and Benefits
- High-Carbon Steel Construction - Provides superior hardness and wear resistance for extended bit life and consistent performance across demanding projects.
- 6-55mm Size Range (Approx. 1/4" to 2-1/8") - Covers a comprehensive spectrum of common hole diameters for hinges, locks, dowels, and cable routing.
- Extended 6-Inch (150mm) Overall Length - Offers enhanced reach for drilling deep mortises or through thick workpieces where standard bits fall short.
- Precision Ground Cutting Edges - Create clean, splinter-free entry and exit holes with minimal tear-out for a professional finish.
- 1/4-Inch Hex Shank - Ensures a secure, non-slip grip in both keyed and keyless chucks, reducing slippage and improving drilling accuracy. Applications
- Door Hardware Installation - Perfect for boring clean, flat-bottomed holes for standard door knob sets, deadbolts, and latch plates.
- Furniture Joinery and Mortising - Ideal for creating precise mortises for table legs, chair rails, and other structural joinery requiring deep, square holes.
- General Woodworking and DIY - Essential for any task requiring a large-diameter hole, such as running plumbing/electrical conduits through studs or creating openings for vents.
- Craft and Hobby Projects - Suitable for precise hole boring in softer woods and materials for custom shelving, signage, and decorative pieces. Note
For optimal performance and longevity, use at recommended speeds for wood and avoid excessive heat buildup. A pilot hole is recommended for larger diameters to guide the bit and reduce strain.
