Drill Bit Art-Pol AR54366 spiral wood, hex shank 16 mm

Spiral wood drill bit Art-Pol AR54366 with a 16 mm working diameter and hex shank is made for drilling precise, clean holes in a variety of wood materials. The spiral flute design efficiently evacuates chips from the bore, reducing clogging and heat buildup during continuous use. The hexagonal shank provides secure grip in chucks and quick-change holders, enabling stable torque transfer when used with hand drills and impact drivers.

Advantages

The spiral flute removes sawdust and wood chips quickly, improving drilling speed and hole quality. A 16 mm cutting diameter offers a consistent bore suitable for dowels, conduit passes, and fitting hardware. The hex shank minimizes slipping in the chuck and allows easy use with quick-change adapters. The bit’s geometry balances cutting efficiency and surface finish, producing smooth hole walls in soft and hard wood, plywood and chipboard.

Suitable for

• Drilling clean holes in softwood and hardwood
• Preparing holes for dowels and wooden connectors
• Creating passage holes for cables and small pipes in wooden elements
• Working with plywood, chipboard and laminated boards
• Use with hand drills and impact drivers that accept hex shank bits

Key specifications

• Working diameter: 16 mm
• Shank type: hexagonal for secure chuck grip
• Flute type: spiral for efficient chip removal
• Material compatibility: softwood, hardwood, plywood, chipboard
• Intended use: manual and powered drilling with standard drill/driver

How to use

Secure the hex shank of the drill bit in the chuck or quick-change holder and tighten firmly. Set the drill to an appropriate speed for the wood type—lower speeds for hardwood and higher speeds for softwood—to avoid burning or splintering. Position the bit perpendicular to the work surface and apply steady, even pressure; allow the bit to cut without forcing. Withdraw the bit periodically on deep holes to clear chips and prevent clogging of the spiral flute.

Usage recommendations

For best results, use a variable-speed drill and start with a pilot mark to center the bit. When drilling laminated or veneered boards, back the workpiece or use a sacrificial backing board to reduce tear-out. Inspect the bit for wear and sharpen or replace when cutting efficiency or hole finish degrades.
