Wood auger bit GEKO 25 x 152 mm HEX for drilling wood, model G37313

The GEKO wood auger bit G37313 is a 25 x 152 mm HEX-shank drill bit designed for creating clean, deep holes in timber. With a 25 mm cutting diameter and 152 mm overall length, this auger bit is suitable for general woodworking and construction tasks where accurate through-holes or fastening holes are required. The HEX shank provides secure grip in compatible chucks and enables quick bit changes when used with hand drills and drill drivers.

Advantages

The auger bit's spiral flute removes chips efficiently to maintain a clean hole and reduce binding. The pointed screw tip helps to draw the bit into the workpiece for controlled progress and consistent hole placement. The HEX shank reduces slippage in the drill chuck and supports rapid interchange of bits when working on multiple holes. Its dimensions balance hole depth and rigidity for common carpentry and joinery applications.

Suitable for

• Boring through-holes in soft and hardwood for bolts and dowels
• Creating holes for fasteners in carpentry and framing
• Drilling long, clean holes in timber for wiring and pipe passage
• General woodworking, joinery and repair tasks

Key specifications

• Cutting diameter: 25 mm
• Overall length: 152 mm
• Shank type: HEX shank for secure grip
• Tip type: screw-point tip for self-feeding
• Flute type: spiral auger flute for chip removal

How to use

Secure the auger bit in a compatible drill or driver with a chuck that accepts HEX shanks. Mark the drilling location and, if needed, clamp the workpiece to prevent movement. Start drilling at low speed to allow the screw tip to engage, then increase speed while applying steady axial pressure. Allow the flute to clear chips periodically on deep holes to maintain cutting efficiency. Withdraw the bit occasionally during long holes to remove accumulated chips and reduce heat buildup.

Usage recommendations

Use appropriate drill speed and avoid excessive lateral force to prolong bit life. For hardwoods, apply moderate feed pressure and clear chips more frequently. Wear eye protection and follow standard safety practices when drilling timber.
