Drill bit Irwin spiral wood hex shank 22 mm 1922002

Irwin spiral wood drill bit with a 22 mm cutting diameter and hexagonal shank is designed for drilling clean, precise holes in timber and wood-based materials. The spiral flute geometry removes chips efficiently while the hex shank ensures a positive grip in chucks and quick changes when used with power drills or drivers that accept hex shanks. This bit is intended for general woodworking, cabinetry and carpentry where controlled hole quality and reliable coupling are required.

Advantages

The spiral flute provides fast chip evacuation to reduce clogging and improve drilling speed. The 22 mm diameter produces a sizeable, consistent hole for dowels, fasteners or conduit passes. The hex shank offers secure retention in hex chucks and impact drivers, minimising slippage and enabling rapid bit swaps. Hardened cutting edges sustain performance during repeated use in soft and hardwoods.

Suitable for

• Drilling clean holes in softwoods and hardwoods
• Creating holes for dowels, bolts and pipes in carpentry
• Cabinetmaking and joinery tasks requiring precise diameters
• Use with power drills and impact drivers with hex chuck

Key specifications

• Cutting diameter: 22 mm
• Shank type: hexagonal for secure chuck engagement
• Flute type: spiral for efficient chip removal
• Material: hardened steel cutting edges (suitable for wood drilling)
• Typical use: manual or powered drilling in timber and wood-based panels

How to use

Secure the drill bit in the hex chuck of a suitable power drill or driver, making sure it is fully seated and tightened. Mark the drilling position on the workpiece and, if needed, clamp the workpiece to prevent movement. Start drilling at low speed to establish the hole, then increase speed while maintaining steady pressure. Withdraw the bit periodically if drilling deep holes to clear chips and avoid overheating. After drilling, clean the bit and store it in a dry place.

Usage recommendations

Use consistent feed pressure and appropriate drill speed for the wood type: lower speeds for hardwoods and higher speeds for softwoods. For precise depth control, use a depth stop or tape on the bit. Avoid using the bit on masonry, metal or reinforced materials to prevent damage.
