Drill bit Art-Pol AR54416 spiral wood hex shank 16 mm

Spiral wood drill bit Art-Pol AR54416 with a 16 mm cutting diameter and hex shank is made for drilling clean, accurate holes in solid timber and wood-based materials. The spiraled flute design evacuates chips efficiently while cutting, reducing friction and helping maintain hole quality. The hexagonal shank provides a stable grip in chucks and quick-change adapters, making this bit compatible with hand drills and drill drivers that accept hex shanks.

Advantages

The spiral flute geometry improves chip removal and reduces clogging during continuous drilling. A 16 mm cutting diameter produces a clear round hole suitable for dowels, conduit entry or through-holes in furniture parts. The hex shank enhances bit retention in quick-change holders and reduces slippage in the chuck compared with round-shank bits. The bit’s construction and cutting profile are optimized for timber and common engineered wood panels, delivering consistent results when used at recommended speeds.

Suitable for

• Carpentry and joinery work requiring precise through-holes and dowel joints
• Installation of fixtures, fittings and small conduits in wooden structures
• Drilling in solid wood, plywood, MDF and particleboard
• Use with hand drills and drill drivers equipped with hex-shank acceptance

Key specifications

• Cutting diameter: 16 mm
• Shank type: hexagonal shank for secure chuck grip
• Flute design: spiral flute for efficient chip removal
• Intended material: timber and wood-based materials
• Drive compatibility: hand drills and drill drivers that accept hex shanks

How to use

Mark the drilling point and secure the workpiece to prevent movement. Select an appropriate drill speed for the material—lower speeds for hardwood, higher speeds for softwoods and thin panels. Insert the hex shank into the drill chuck or quick-change adapter and tighten securely. Begin drilling with steady pressure; allow the spiral flute to remove chips and withdraw the bit periodically for deep holes to clear debris and avoid overheating. After use, clean wood particles from the flute and inspect the cutting edge for wear.

Usage recommendations

For best performance, use lubricant or cutting wax only when drilling engineered panels that tend to gum the cutting edge, and avoid excess lateral force to maintain hole roundness. Store the bit in a dry place and replace it once the cutting edges show visible wear or produce tear-out in finished surfaces.
