Drill Bit Art-Pol wood auger 20 x 460 mm AR54420

Art-Pol wood auger drill bit 20 x 460 mm AR54420 is a long-shank auger designed for drilling deep, clean holes in timber and large wooden components. With a 20 mm cutting diameter and a 460 mm overall length, this auger is intended for tasks that require through-holes or deep boreholes in softwoods and many hardwoods. The bit is compatible with hand braces and power drills that accept traditional auger-style bits, providing steady chip extraction and accurate guidance for longer bores.

Advantages

The design delivers stable, straight drilling with efficient chip removal, reducing clogging during deep bores. Its 20 mm cutting diameter produces uniform holes for dowels, bolts or conduits, while the extended length lets you reach through thick beams or assemblies without repositioning. The auger profile offers reliable centring and smoother starts compared with general-purpose twist bits, minimizing tear-out on entry and exit when used correctly.

Suitable for

• Drilling through-holes in beams and joists
• Creating deep boreholes for dowels and long fasteners
• Carpentry, joinery and timber framing tasks
• Fieldwork with hand braces or portable drills

Key specifications

• Cutting diameter: 20 mm
• Overall length: 460 mm
• Suitable materials: softwood and many hardwoods
• Bit type: auger-style fluted bit for chip removal
• Compatible drive: standard shank for auger/drill chucks and hand braces

How to use

Secure the workpiece and mark the drilling position. Fit the auger into a compatible drill chuck or hand brace and ensure the bit is tightened. Start drilling at low speed to allow the auger point to centre, then increase speed while applying steady, even pressure. Periodically retract the bit to clear chips and prevent clogging, especially when drilling long holes. For cleaner exit holes in hardwoods, consider backing the workpiece with sacrificial material.

Usage recommendations

Use appropriate personal protective equipment, maintain steady feed rate, and clear chips regularly to extend bit life. Match drilling speed and pressure to the wood species—lower speeds for hardwoods and higher speeds for softwoods. Inspect the bit for damage before use and sharpen or replace if cutting performance declines.
