## Summary description

Spiral wood drill bit by GRAPHITE with a hexagonal shank and 12 mm cutting diameter (model 57H358). Designed for drilling clean holes in wood and wood-based materials. The spiral flute removes chips efficiently while the hex shank provides secure clamping in chucks and quick-change adapters. Suitable for handheld drills and drill drivers in carpentry and general woodwork.

## Long description

GRAPHITE spiral wood drill bit with a 12 mm cutting diameter and hexagonal shank is made for drilling clean, accurate holes in solid wood and common wood-based materials. The spiral flute design evacuates chips efficiently to reduce clogging and to maintain cutting performance, while the hex shank ensures secure clamping in standard chucks and quick-change adapters. This drill bit is compatible with handheld corded and cordless drills and drivers used in carpentry, furniture assembly and general woodwork.
Advantages
The spiral flute provides effective chip removal for smoother drilling and less tear-out on the workpiece surface. The sharp cutting edge and central point aid in precise centring and consistent hole diameter. The hexagonal shank reduces slipping in the chuck or quick-change adaptor, enabling faster bit changes and more reliable torque transfer. The 12 mm diameter suits medium-sized holes commonly needed for dowels, fittings and through-holes in joinery.
Suitable for
Drilling through solid wood, softwood and hardwood
Working with plywood, MDF and particle board
Carpentry, furniture assembly and fitting hardware
Handheld drilling with corded or cordless drills and drivers
Key specifications
Cutting diameter: 12 mm
Shank type: hexagonal
Flute design: spiral for chip evacuation
Primary application: wood and wood-based materials
Compatibility: designed for standard chucks and quick-change adapters
How to use
Secure the drill bit in the drill’s chuck or quick-change adapter, making sure the hex shank is fully seated to prevent slipping. Mark and centre the drilling point on the workpiece. Start drilling at low speed to establish the position, then increase speed while applying steady, moderate pressure. Allow the spiral flute to remove chips naturally; retract periodically when drilling deeper holes to clear built-up material. After use, clean the flute and store the bit dry to prevent corrosion.
Usage recommendations
Use appropriate drill speed for the wood type—lower speeds for hardwoods and higher speeds for softwoods—and apply consistent pressure without forcing the bit. For precise, clean edges, clamp the workpiece or use a backing board to reduce splintering. Wear eye protection and follow standard workshop safety practices.
