## Long description

Spiral drill bit by GRAPHITE for wood, 16 mm diameter with a hexagonal shank designed to provide reliable engagement in chucks and quick-change drivers. The spiral flute design evacuates chips efficiently to help maintain cutting speed and reduce clogging when drilling through soft and hardwoods. This 16 mm wood bit is intended for creating clean through-holes or pilot holes in timber for carpentry, cabinet making and general DIY tasks.
Advantages
The spiral flute improves chip removal and reduces heat build-up during continuous drilling. A hexagonal shank offers secure grip in quick-change chucks and reduces slipping compared with round shanks. The 16 mm cutting diameter delivers a consistent hole size suitable for dowels, fasteners or pass-throughs. The bit balances rigidity and cutting performance to provide stable, straight drilling in timber.
Suitable for
Drilling through-holes in softwoods and hardwoods
Cabinet making and furniture assembly
Carpentry and joinery tasks
DIY projects requiring 16 mm holes for dowels or fittings
Key specifications
Diameter: 16 mm
Tip type: spiral cutting geometry for wood
Shank type: hexagonal shank for secure chuck engagement
Application: designed for drilling timber and wood-based materials
Flute: spiral flute for efficient chip evacuation
How to use
Install the drill bit securely in a compatible chuck or quick-change holder, ensuring the hex shank seats fully for minimal play. Use appropriate drilling speed for the timber species—lower speeds for hardwoods and higher speeds for softwoods—while applying steady, even pressure. Withdraw the bit periodically on long holes to clear chips and avoid overheating. Support the workpiece properly or clamp it to prevent movement and ensure straight holes.
Usage recommendations
Wear suitable eye protection and hearing protection when drilling. For best results, pre-mark hole centers and pilot spots when precision alignment is required. Use a backing piece when drilling through thin panels to avoid splintering at the exit side.
