Drill Bit Art-Pol AR54425 for Wood, Spiral Hex Shank, 25 mm

Art-Pol AR54425 is a 25 mm spiral drill bit engineered for drilling wood. The flute geometry and sharp cutting edges are designed to produce clean holes and support efficient chip evacuation, while the hexagonal shank ensures a secure fit in standard chucks and quick-change holders. Intended for general woodworking tasks, this wood drill bit works with drills and drivers that accept hex shanks and is suitable for use in both softwoods and many hardwoods.

Advantages

The spiral flute design improves chip removal and reduces clogging, resulting in faster and cleaner drilling. The 25 mm cutting diameter provides a consistent hole size for plugs, dowels and fittings. The hex shank improves grip and reduces slippage in the chuck or bit holder, enabling stable rotation and more accurate hole placement. The bit’s geometry is optimized for wood to minimise tear-out along grain and to extend the usable life under normal woodworking conditions.

Suitable for

• Drilling holes for wooden plugs and dowels
• Creating fitting holes for hinges, locks and furniture fittings
• Through-holes and stopped holes in softwood and many hardwoods
• Use with hand-held drills and cordless drivers that accept hex shanks

Key specifications

• Cutting diameter: 25 mm
• Material application: wood (softwood and many hardwoods)
• Tip and flute type: spiral flute for chip evacuation
• Shank type: hexagonal shank for secure grip
• Compatibility: standard drills and quick-change holders that accept hex shanks

How to use

Secure the drill bit in the chuck or quick-change holder, ensuring the hex shank is fully seated to prevent wobble. Mark the drilling position on the workpiece and start drilling at low speed to establish the hole, then increase speed as needed while maintaining steady pressure. Withdraw the bit occasionally on deeper holes to clear chips if necessary. For clean edges and to reduce splintering on the exit side, consider backing the workpiece with scrap wood or use a sacrificial backing board.

Usage recommendations

Use appropriate drilling speeds for the wood species being worked: lower speeds for hard and dense woods, higher speeds for softwoods. Apply consistent axial pressure without forcing the bit, and inspect the cutting edges periodically; resharpen or replace the bit when cutting performance declines. Wear eye protection and follow standard workshop safety precautions when drilling.
