Drill Bit Art-Pol Auger for Wood 25 mm x 235 mm (model 54375)

Art-Pol auger drill bit for wood with a 25 mm cutting diameter and 235 mm overall length is designed to create clean, deep holes in soft and hardwoods. The drill bit features a pointed tip for accurate centring and a spiral flute that evacuates chips efficiently, allowing continuous drilling without frequent clearing. Compatible with manual braces and standard drill chucks, this auger bit is intended for woodworking, carpentry and installation tasks requiring precise, deep boreholes.

Advantages

The spiral flute design improves chip removal and reduces clogging during prolonged drilling in wood. A sharp, pointed tip ensures reliable self-centring and reduces walking at the start of the hole. The 25 mm cutting diameter provides a balance between hole size and material removal rate, while the 235 mm overall length enables drilling through thicker boards and assemblies. The construction is optimised for steady cutting and consistent hole geometry in both softwoods and most hardwoods.

Suitable for

• Drilling deep holes in timber beams and planks
• Installing door hardware, hinges and locks where deep pilot holes are required
• Creating passageways for cables and pipes in wooden structures
• Traditional carpentry and joinery tasks using a brace or power drill

Key specifications

• Cutting diameter: 25 mm
• Overall length: 235 mm
• Tip type: Pointed centring tip for accurate starts
• Flute type: Spiral flute for efficient chip evacuation
• Intended material: Softwood and hardwood
• Compatible drives: Manual brace or standard drill chucks

How to use

Secure the auger bit in a compatible chuck or brace, ensuring it is held straight and firmly. Mark the drilling point on the workpiece and position the pointed tip to start the hole; apply steady axial pressure while rotating at a moderate speed to allow the spiral flute to remove chips effectively. Periodically withdraw the bit to clear accumulated shavings when drilling deep holes, then continue until the required depth is reached. When using power drills, select a low to moderate speed appropriate for the wood species to prevent overheating or burning the hole edges.

Usage recommendations

Use clamps or supports to stabilise the workpiece and wear appropriate eye protection. For best results in hardwoods, pre-drill a small starter hole if extreme precision is required, and clear chips frequently to maintain cutting efficiency and prevent binding.
