Drill bit Art-Pol AR54490 spiral 40 mm diameter

The Art-Pol AR54490 spiral drill bit with a 40 mm diameter is a single-piece cutting tool designed for producing large round holes where a robust bore is required. Its spiral flute geometry helps evacuate chips during cutting, maintaining a cleaner hole and more consistent cutting conditions. The bit is intended for use with compatible drill machines and appropriate holders that can accept its diameter and mounting method.

Advantages

The single-piece construction enhances rigidity and reduces the risk of breakage under load. Spiral flutes promote efficient chip removal and reduce clogging, which supports more stable cutting and extended life when used correctly. The 40 mm cutting diameter enables larger hole making without the need for multiple smaller passes, improving work efficiency for applicable tasks.

Suitable for

• Creating large round holes in materials compatible with the bit design
• Workshop drilling tasks that require a single-step bore of 40 mm
• Use with compatible bench drills, drill presses, or portable drills with suitable holders

Key specifications

• Cutting diameter: 40 mm
• Design: single-piece spiral flute geometry for chip evacuation
• Application: for producing round holes with a large bore
• Compatibility: for use with drill machines and holders suited to the diameter and mounting method

How to use

Mount the drill bit securely in a compatible chuck or holder rated for the 40 mm diameter and ensure the drilling machine is correctly aligned. Select appropriate spindle speed and feed rate for the work material, and apply steady, even pressure while keeping the tool perpendicular to the work surface. Periodically withdraw the bit to clear chips if cutting conditions produce heavy swarf, and inspect the hole and cutting edges for heat or wear during extended operations.

Usage recommendations

Use cutting fluid or coolant appropriate to the work material to reduce heat and improve chip evacuation. Confirm that the drill machine and holder provide adequate clearance and support for a 40 mm diameter bit to minimise runout and vibration. Match speeds and feeds to the material being drilled and replace the bit if signs of excessive wear or damage appear.
