Fast, clean holes in wood without splintering. These flat wood drill bits are engineered for reliable performance in door, electrical and plumbing jobs where accurate, repeatable holes matter. Key benefits Cleancut holes: precisionground points and angled cutting edges produce smooth, accurate holes with minimal tearout. Reduced splintering: tripoint center cutters plus twin side cutters stabilize the bit and cut clean edges to prevent wood from splintering. Positive grip and quick changes: 1/4' hex powerdrive quickchange shank reduces slipping in threejaw chucks and speeds bit changes. Durable construction: made from grade carbon steel for strength and wear resistance during repeated use. Main features Bit type: flat wood drill bits with tripoint and twin side cutters Length: 152 mm for all bits Sizes included: 10 mm, 12 mm, 16 mm, 18 mm, 20 mm, 25 mm Shank: 1/4' hex powerdrive (quickchange compatible) Materials: grade carbon steel for: wood, chipboard and plasterboard Practical applications (examples) Door hardware: quickly drill precise holes for door locks and latch plates without chipping the surrounding wood. Electrical installation: bore neat holes for wiring, conduit entry or mounting back boxes in wood and plasterboard. Plumbing and carpentry: make clean holes for pipe passes, brackets, or fittings in timber and chipboard. Why this set solves common problems Avoids messy, jagged holes that require sanding or patching. Provides consistent results across multiple hole diameters useful for typical trade tasks. Hex shank compatibility minimizes bit slippage under load, improving control and safety.
