Wood drill bit GEKO HEX 50 x 152 mm

GEKO HEX 50 x 152 mm wood drill bit is a specialist cutting tool designed for creating large-diameter holes in timber and soft wood materials. With a 50 mm cutting diameter and a 152 mm overall length, this bit provides the reach and size needed for through-holes and deep seating applications. The HEX shank delivers a positive, slip-resistant connection with chucks and quick-change holders, simplifying tool changes and maintaining concentricity during drilling. The flute and cutting edge geometry are optimized for chip evacuation and clean hole walls typical of carpentry and furniture-making tasks.

Advantages

The HEX shank design reduces slippage in powered chucks and impact drivers, enabling reliable torque transfer for larger holes. Its 50 mm diameter produces clean, consistent hole profiles while the 152 mm length allows for deeper penetration into beams or stacked wood. The bit construction balances rigidity and cutting performance to limit wobble and achieve smooth finishes on softwood surfaces. Overall, it is practical for both professional tradespeople and DIY users needing a robust, easy-to-change large-diameter wood bit.

Suitable for

• Drilling large through-holes in structural timber and beams
• Creating recesses and pull-through holes for pipes, cables, and dowels
• Furniture making and joinery where precise large-diameter holes are required
• Carpentry and on-site construction work with cordless or corded drills

Key specifications

• Cutting diameter: 50 mm
• Overall length: 152 mm
• Shank type: HEX shank for secure grip
• Material compatibility: timber and soft wood materials
• Intended use: large-diameter and deep-hole wood drilling

How to use

Secure the GEKO HEX wood drill bit in a compatible chuck or quick-change holder so that the HEX shank seats fully. Mark the drilling position on the workpiece and clamp the timber to prevent movement. Start drilling at low speed to create a pilot groove, then increase speed while applying steady, moderate pressure to allow efficient chip removal. Periodically withdraw the bit to clear chips when drilling deep holes and avoid excessive heat build-up. After use, clean the bit of wood debris and store it in a dry place.

Usage recommendations

Use the bit with appropriate protective equipment and clamp the workpiece securely. Select drill speeds appropriate for the wood species—lower speeds for hardwoods and higher speeds for softwoods—and clear chips often to maintain cutting efficiency and hole quality.
