Drill bit Irwin spiral wood hex shank 10 mm — model 10502745

The Irwin spiral wood drill bit with a 10 mm cutting diameter and hex shank is designed for creating clean, accurate holes in solid wood and wood-based panels. Its spiral flute geometry evacuates chips efficiently to reduce clogging while the hexagonal shank provides a secure grip in chucks and quick-change adapters. The bit is suitable for use in handheld drills and impact drivers when working on carpentry, fittings, or installation tasks.

Advantages

This 10 mm spiral wood drill bit features a geometry that promotes fast chip removal and minimizes tear-out on entry and exit. The hex shank design ensures stable, slip-resistant engagement with drill chucks and quick-change systems, enabling consistent drilling performance. Manufactured to the brand's typical quality standards, the bit maintains cutting accuracy and facilitates repeatable hole dimensions in wood and composite panels.

Suitable for

• Drilling holes in soft and hard wood
• Preparing pilot or clearance holes in furniture assembly
• Working with plywood, MDF and particleboard
• Use with handheld electric drills and impact drivers

Key specifications

• Cutting diameter: 10 mm
• Shaft type: hexagonal shank for secure chuck engagement
• Flute type: spiral flute for efficient chip evacuation
• Intended material: wood and wood-based materials
• Typical applications: carpentry, furniture assembly, installation tasks

How to use

Secure the drill bit in the drill chuck or quick-change adapter, ensuring the hex shank seats fully to prevent slipping. Select an appropriate drilling speed for the wood species and apply steady, moderate feed pressure. Allow the spiral flute to clear chips by periodically withdrawing the bit on deep holes. After completing each hole, inspect the cutting edge for wear and clean chips from the flute to maintain performance.

Usage recommendations

Use lower speeds and firm support when drilling hardwoods to avoid overheating. For through-holes, back the bit out periodically to clear chips; for clean entry and exit, consider using a sacrificial backing board to reduce tear-out. Replace the bit when cutting performance or hole quality declines.
