Drill bit Art-Pol AR54440 40 mm spiral, hexagonal shank

Spiral drill bit Art-Pol AR54440 40 mm with hexagonal shank is a large-diameter spiral cutter designed for drilling sizeable holes in a variety of materials. The tool combines a 40 mm cutting diameter with a spiral flute geometry to remove chips efficiently, and a hexagonal shank for positive engagement with chucks or quick-change holders. It is intended for use with compatible drills and drivers where a robust, large spiral bit is required.

Advantages

The spiral flute accelerates chip evacuation and reduces clogging during continuous drilling. The 40 mm diameter provides a wide bore capacity for applications that require larger hole sizes. The hexagonal shank ensures secure grip in chucks and reduces slippage in quick-change systems. The design balances cutting performance and stability to support straight, consistent hole formation.

Suitable for

• Drilling large-diameter holes in metal components
• Creating wide bores in wood and timber
• General-purpose large-hole drilling in construction and fabrication
• Use with compatible corded and cordless drills with appropriate power and chuck or adapter

Key specifications

• Cutting diameter: 40 mm
• Flute type: Spiral
• Shank type: Hexagonal
• Intended use: Large-hole drilling in metal, wood and general materials

How to use

Secure the drill bit in a compatible chuck or quick-change holder ensuring the hexagonal shank is fully engaged. Select drill speed and feed appropriate for the material being drilled — lower speeds for metals, moderate speeds for wood. Apply steady axial pressure and allow the spiral flutes to evacuate chips; retract periodically if chips accumulate. Use cutting fluid when drilling metal to reduce heat and extend bit life. After use, clean chips from the flutes and store the bit to prevent corrosion and damage.

Usage recommendations

Use a drill with sufficient torque and a stable support or guide when drilling large 40 mm holes. For metalwork, apply suitable cutting lubricant and moderate feed to avoid overheating. When drilling in wood, clamp the workpiece and start with a pilot mark to improve accuracy. Inspect the bit before use for signs of wear and replace if cutting performance deteriorates.
