Drill Bit Art-Pol AR54486 spiral 36 mm

Spiral drill bit Art-Pol AR54486 with a 36 mm diameter is a wide-diameter twist bit intended for drilling applications that require a clean, large hole. The spiral geometry supports continuous chip evacuation and enhances drilling stability, making it suitable for use in wood and other soft materials. This bit is designed to work with compatible hand-held power drills and drill presses when a 36 mm hole is needed for joinery, fittings, or installation tasks.

Advantages

The spiral (twist) design promotes efficient chip removal, reducing clogging and heat build-up during operation. Its 36 mm cutting diameter provides a single-pass solution for larger holes, saving time compared with incremental drilling with smaller bits. The bit’s geometry contributes to smoother drilling and more consistent hole dimensions, while the solid shank ensures secure clamping in standard chucks.

Suitable for

• Drilling 36 mm diameter holes in softwood and plywood
• Creating openings for fittings, dowels, and bushings
• General-purpose large-diameter holes in non-metal materials

Key specifications

• Cutting diameter: 36 mm
• Geometry: spiral (twist) flute for chip evacuation
• Intended materials: wood and similar soft materials
• Compatibility: designed for use with standard power drills and drill presses
• Shank type: solid round shank for chuck clamping

How to use

Secure the drill bit firmly in the drill chuck so the shank is fully inserted and tightened. Mark the hole location and, if necessary, use a pilot punch or small pilot hole to guide the bit. Operate the drill at a steady speed appropriate for wood: moderate to high RPM for clean cutting, avoiding excessive feed pressure to prevent binding. Periodically withdraw the bit to clear chips and allow cooling. For drill press use, align the workpiece and clamp it securely before drilling to maintain accuracy and safety.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and hearing protection. When drilling deeper holes, retract the bit frequently to remove chips and reduce heat. For best results in laminated or veneered materials, place a sacrificial backing board beneath the workpiece to minimize tear-out on the exit side.
