Twist Wood Drill Bit GEKO model G37410 Ø14 x 460 mm for timber and log drilling, pack 25/50

GEKO G37410 is a twist wood drill bit with a 14 mm cutting diameter and an overall length of 460 mm, designed for drilling timber, logs and other thick wooden elements. The bit combines a spiral (auger-style) flute for efficient chip evacuation with a pointed tip that centers and starts the hole accurately. Supplied in a pack configuration of 25/50 pieces, this drill bit is intended for repetitive tasks in carpentry, construction and general woodworking where deeper holes through solid wood are required.

Advantages

The long spiral flute provides continuous chip removal along the entire 460 mm length, reducing binding and heat build-up during deep drilling. The 14 mm diameter delivers a standardized bore suitable for dowels, bolts and through-holes in structural timber. Its auger-style geometry improves bite and stability when used in hand-held drills or drill presses, while the robust shaft supports repeated use in demanding jobsite conditions.

Suitable for

• Drilling through solid timber and logs
• Creating dowel or bolt holes in wooden beams and posts
• Deep-hole drilling in carpentry and joinery
• Preparation of holes for structural connections in construction

Key specifications

• Cutting diameter: 14 mm
• Total length: 460 mm
• Flute type: twist/auger-style spiral for chip evacuation
• Intended material: timber, logs and thick wooden elements
• Pack quantity: 25 or 50 pieces
• Typical use: manual and machine drilling (hand drills, drill presses)

How to use

Select a drill with a compatible chuck capacity and secure the GEKO twist wood drill bit firmly in the chuck. Mark the drilling position on the wood and, if accuracy is required, use a center punch or pilot mark. Begin drilling at low speed to engage the tip, then increase speed as the flute clears chips. Apply steady axial pressure; allow the auger flute to eject chips and avoid excessive force that could cause binding. For deep holes, periodically withdraw the bit to clear accumulated chips and prevent overheating. When finished, withdraw the bit slowly while the drill is still turning to reduce splintering at the exit.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. For best results, match drill speed and feed rate to the timber species and moisture content; softer woods generally allow higher speeds while hardwoods require slower speeds and more gradual feed. Maintain the cutting edge by sharpening or replacing bits when wear reduces performance.
