Drill bit Irwin auger hex 32 mm, model 1922005, for wood, hex shank

Irwin auger drill bit 32 mm is designed for drilling clean, deep holes in solid wood and engineered timber. The auger flute geometry allows efficient extraction of wood chips while maintaining bore concentricity, and the hex shank provides a secure grip in chucks and impact drivers. This drill bit is intended for professional and workshop use where speed, accuracy and reliable chip evacuation are required.

Advantages

The auger flute design ensures rapid and continuous chip removal, reducing clogging and preventing burn marks on the workpiece. The sharp cutting edge and screw tip help to pull the bit into the material for controlled, low-force drilling. The hex shank delivers positive engagement with compatible chucks and impact drivers, minimising slippage and making bit changes quick and stable.

Suitable for

• Drilling deep, clean holes in solid wood and soft to medium hardwoods
• Carpentry and joinery tasks requiring accurate hole placement
• Timber construction and framing where long holes are needed
• Use with corded or cordless drills and impact drivers that accept hex shanks

Key specifications

• Cutting diameter: 32 mm
• Tip type: auger with screw point for self-feeding
• Shank type: hex shank for secure grip in chucks and impact drivers
• Flute: single auger flute for efficient chip removal
• Material: high-strength tool steel suitable for wood drilling

How to use

Mount the auger bit securely in a compatible drill or impact driver that accepts hex shanks. Position the screw tip on the marked drilling point and start at low speed until the tip engages, then increase speed as appropriate for the wood species and drill capacity. Apply steady, even pressure and allow the auger flute to evacuate chips; periodically withdraw the bit for very deep holes to clear accumulated chips and avoid binding. After use, clean wood debris from the flute and store the bit dry to protect the cutting edge.

Usage recommendations

For best results, use appropriate drill speeds for the wood type: lower speeds for hardwoods and higher speeds for softwoods. Use steady feed pressure and keep the bit sharp to maintain clean hole edges. When drilling long or deep holes, withdraw the bit at intervals to remove chips and reduce heat build-up.
