Drill Bit Art-Pol spiral wood hex shank 18 mm AR54368

Art-Pol spiral wood drill bit AR54368 with an 18 mm cutting diameter and a hexagonal shank is designed for drilling clean, precise holes in a range of wood materials. The spiral flute geometry promotes efficient chip evacuation and reduces clogging when working with softwood, hardwood, plywood and chipboard. The hex shank ensures a secure grip in quick-change adapters and standard drill chucks, making the bit suitable for both handheld and stationary drilling operations.

Advantages

The spiral flute design provides smooth cutting action and rapid chip removal, which helps maintain consistent hole quality and reduces the risk of tear-out. The 18 mm diameter delivers a balance between hole size and structural integrity for common woodworking tasks. The hexagonal shank prevents slipping under load and allows fast bit changes in impact drivers and quick-change chucks. The robust geometry is suitable for repeated use in carpentry and furniture-making applications.

Suitable for

• Drilling through softwood and hardwood
• Creating holes in plywood and chipboard
• Carpentry and general woodworking tasks
• Furniture making and assembly

Key specifications

• Cutting diameter: 18 mm
• Shank type: hexagonal shank for secure grip
• Flute type: spiral flutes for chip evacuation
• Compatible tools: handheld drills, stationary drill presses, quick-change adapters
• Material suitability: softwood, hardwood, plywood, chipboard

How to use

Clamp the workpiece securely and mark the drilling position. Insert the hex shank into the drill chuck or quick-change adapter and tighten to eliminate play. Start drilling at low speed to establish the hole, then increase speed as needed while maintaining steady pressure and alignment. Use moderate feed force to allow the spiral flutes to remove chips efficiently. Withdraw the bit periodically for deep holes to clear accumulated chips and prevent overheating.

Usage recommendations

For best results, use appropriate drill speeds for the material being worked (slower for hardwood, faster for softwood), keep the bit sharp, and avoid excessive axial force. When drilling finished surfaces, consider using a backing board to reduce tear-out. Inspect the bit before use and replace if worn or damaged.
