Twist auger bit GEKO G37402 for wood 6 x 460 mm (25/100)

The Twist auger bit GEKO G37402 for wood 6 x 460 mm (25/100) is a spiral auger designed to create straight, deep boreholes in timber and common wooden construction materials. With a 6 mm diameter and a 460 mm overall length, the bit provides an extended cutting length suitable for drilling through thick boards, beams and studs. The auger-style flute and screw point help maintain alignment and remove wood chips efficiently during drilling with handheld drills or drill drivers.

Advantages

The spiral geometry and screw tip ensure stable centring and continuous feed into the workpiece, reducing walking and the need for pilot holes. Its long working length enables deep, through-holes and partially blind holes in structural timber without switching to multiple shorter bits. The fluted design promotes fast chip evacuation, helping to prevent jamming and heat build-up while preserving hole accuracy over long depths.

Suitable for

• Drilling deep holes in timber, beams and studs
• Carpentry and joinery tasks requiring straight bores
• Timber framing and structural woodwork
• Installing dowels, running wiring or pipes through wooden elements

Key specifications

• Diameter: 6 mm
• Overall length: 460 mm
• Type: twist/auger wood bit with screw point
• Intended material: timber and common wooden construction materials
• Compatibility: handheld drills and drill drivers

How to use

Secure the bit in the drill chuck so the shank sits firmly without play. Mark the drilling position on the workpiece and, if needed, clamp the material to prevent movement. Start drilling at low speed to engage the screw tip and establish the bore, then increase speed moderately while applying steady axial pressure. Allow the flutes to clear chips periodically when drilling deep holes; withdraw the bit slightly if chips accumulate. Finish the hole by slowing the drill and backing out while the chuck is still rotating to avoid splintering at the exit side.

Usage recommendations

For best results use moderate speed and steady feed; excessive torque or very high speed can cause overheating or breakage on long thin bits. Clamp longer workpieces and support the drill to maintain straightness. When drilling fully through thick timbers, withdraw the bit occasionally to clear chips and prevent binding.
