## Long description

GRAPHITE spiral wood drill bit, 18 mm diameter with a hexagonal shank, is made for drilling precise, clean holes in timber and common wood-based materials. The spiral flute evacuates chips effectively to maintain a stable drilling action and reduce clogging, while the hex shank offers reliable engagement with chucks and quick-change holders. Designed for use with hand drills and cordless drivers, this bit suits carpentry, joinery and general construction tasks where accuracy and chip removal are important.
Advantages
The spiral flute geometry provides continuous chip removal and helps produce smooth hole walls. The 18 mm diameter offers a balance between hole size and control for many woodworking tasks. The hex shank ensures a secure grip in standard chucks and quick-change adapters, reducing slippage during higher-torque operations. The bit’s construction is optimized for timber and typical engineered wood, enabling consistent drilling performance in through-holes and stop-holes.
Suitable for
Drilling clean holes in soft and hardwoods
Carpentry and joinery work
On-site construction and renovation tasks
Installation of dowels, conduits, and fasteners
Use with hand drills and cordless drivers
Key specifications

Tip and flute type: spiral flute for chip removal
Shank type: hexagonal shank for secure grip
Intended material: timber and common wood-based materials

How to use
Mark the drilling point and secure the workpiece to prevent movement. Select an appropriate rotation speed for the wood species and drill steadily without excessive pressure to allow the spiral flute to evacuate chips. Fit the hex shank into the drill chuck or quick-change adapter ensuring it is fully seated. For deeper holes, withdraw the bit periodically to clear chips and prevent overheating. After use, clean the flute and store the bit in a protective holder to maintain cutting efficiency.
Usage recommendations
Use moderate drill speeds for hardwoods and higher speeds for softwoods, and consider pilot holes for precise alignment when installing dowels or fasteners. Keep the bit sharp and free of resin build-up to ensure consistent hole quality.
