## Long description

Irwin spiral wood drill bit with a 12 mm cutting diameter and hexagonal shank is designed for efficient drilling in a variety of wood materials. The spiral flute rapidly evacuates wood chips while the ground cutting edges deliver clean entry and reduced tear-out. The hex shank ensures positive grip in chucks and quick-change drivers, supporting steady drilling performance with handheld drills and impact drivers used in woodworking, joinery and general carpentry.
Advantages
The spiral flute geometry improves chip removal and reduces clogging during extended drilling operations. A precisely ground tip and cutting edges provide accurate centering and cleaner holes compared with simpler twist bits. The hexagonal shank prevents slippage in chucks and rapid-change adapters, enabling quick bit changes and secure torque transmission. The 12 mm diameter offers a balance between material removal and control for common joinery and installation tasks.
Suitable for
 Drilling holes in softwoods and hardwoods for carpentry and joinery
 Installing dowels, plugs and fasteners
 Creating starter holes for screws and bolt fittings
 Use with handheld drills and impact drivers for on-site work
Key specifications
 Cutting diameter: 12 mm
 Shank type: hexagonal shank for secure grip and quick-change systems
 Flute type: spiral flute for efficient chip evacuation
 Material application: designed for wood materials including softwood and hardwood
 Recommended tools: handheld drills and impact drivers
How to use
Install the bit securely in the drill chuck or quick-change adapter, ensuring the hex shank is fully seated. Select a drilling speed appropriate to the wood type—moderate speed for hardwoods and higher speed for softwoods—and apply steady, moderate pressure. Allow the spiral flute to clear chips periodically on deep holes and retract occasionally to evacuate debris. For precise holes, mark the drilling point and use a pilot or centering function on the drill where available.
Usage recommendations
Avoid excessive side pressure and high speeds on hard materials to reduce wear. Use a backing piece when drilling through thin stock to minimize tear-out on the exit side. Keep the bit clean and sharpen or replace when cutting edges become dull to maintain hole quality and safe operation.
