## Long description

Spiral drill bit by GRAPHITE for wood with a 25 mm cutting diameter and a hexagonal shank suitable for secure chucking in drills and drivers. The fluted spiral geometry evacuates chips effectively, helping to maintain steady penetration and cleaner holes in both softwoods and hardwoods. Designed for woodworking tasks that require a precise 25 mm bore, this bit offers a balance of cutting performance and stability for manual and powered drilling.
Advantages
The spiral flute design ensures efficient chip removal, reducing clogging and heat build-up during continuous drilling. A 25 mm cutting diameter provides a large, accurate hole size commonly needed in carpentry and furniture making. The hexagonal shank improves grip in chucks and quick-change adapters, minimizing slipping and improving torque transfer. The bit’s geometry is optimized for wood to produce a clean entry and exit with reduced tear-out when used correctly.
Suitable for
 Drilling clean 25 mm holes in softwoods and hardwoods
 Carpentry, joinery and furniture assembly
 Installing dowels, bushings or large-diameter fittings
 General DIY woodworking and renovation tasks
Key specifications
 Material application: wood (softwood and hardwood)
 Tip and flute type: spiral flute for chip evacuation
 Shank type: hexagonal shank for secure gripping
 Cutting diameter: 25 mm
 Typical compatible tools: hand drills, drill drivers, quick-change chucks
How to use
Secure the drill bit in a compatible chuck or quick-change adapter ensuring the hexagonal shank is fully seated to prevent slippage. Mark the drilling position and, if required, use a centre punch or pilot mark to guide the bit. Start drilling at low speed to establish the hole, then increase speed and apply steady, even pressure. Allow the spiral flutes to clear chips; periodically withdraw the bit for deep holes to remove debris and avoid overheating. Finish the hole with steady control to minimize tear-out on the exit face.
Usage recommendations
Use the bit at moderate to high speeds appropriate for the wood species; reduce speed and feed for dense hardwoods. For improved results, clamp workpieces securely, back the exit side with sacrificial backing to reduce splintering, and keep the bit sharp and free of resin build-up. Inspect the shank and flutes before each use and replace the bit if excessive wear or damage is observed.
