Wood Auger Bit GEKO G37406 10 x 460 mm (25/100) – spiral drill for wood

GEKO G37406 is a spiral wood auger bit measuring 10 x 460 mm (25/100). It is designed to drill deep, clean holes in timber and softwood, combining a sharpened, pointed tip for precise centring with a continuous spiral flute that evacuates chips efficiently. The bit is suitable for use with hand braces and compatible power drills when an appropriate chuck or adapter is used, and is intended for through-holes, dowel preparation and other joinery tasks where a smooth bore and controlled feed are required.

Advantages

The spiral geometry promotes fast chip removal and reduces clogging during deep-hole drilling. A pointed pilot tip ensures accurate starts and minimises wandering on wood surfaces. The elongated working length provides access to thick workpieces and allows drilling through stacked boards without repositioning. The construction balances durability and cutting performance for repetitive carpentry and construction use.

Suitable for

• Drilling through-holes in timber and softwood
• Preparing dowel and tenon holes
• Carpentry and joinery tasks requiring deep, straight bores
• Work with hand braces or power drills with suitable chucks/adapters

Key specifications

• Nominal diameter: 10 mm
• Overall working length: 460 mm
• Spiral flute for chip evacuation
• Pointed pilot tip for accurate positioning
• Designed for timber and softwood

How to use

Secure the auger bit in a compatible chuck or hand brace according to the tool manufacturer’s instructions. Mark the drilling position and align the pilot tip with the mark. Apply steady, even pressure while turning the bit; allow the spiraled flute to remove chips and withdraw periodically if necessary to clear debris. For power drilling, use an appropriate speed for wood and avoid excessive force to prevent overheating or breakage. After drilling, clean wood fibres from the hole and inspect for required fit of dowels or fasteners.

Usage recommendations

Use the bit at moderate speeds appropriate for the wood species; for dense hardwoods reduce cutting speed and apply incremental feeds. Keep the bit sharp and free of resin build-up for consistent performance. When drilling long holes, clear chips frequently to maintain cutting efficiency and reduce torque load on the drill or brace.
