Drill Bit GEKO Wood Auger G37360 — 14 x 230 mm spiral wood bit (pack 25/100)

Spiral wood auger drill bit GEKO G37360, size 14 x 230 mm, is designed for drilling accurate, deep holes in soft and hardwoods. The bit features a twisted flute for efficient chip evacuation and a pointed screw tip that enables self-feeding into the material, reducing the need for excessive pressure. Its length and geometry make it suitable for long-reach drilling in timber, framing, door and window installations, and other woodworking or construction tasks where clean bores are required.

Advantages

The spiral flute design provides continuous chip removal, helping to maintain hole quality and reduce clogging during deep drilling. The screw tip centres the bit automatically and improves feed control, resulting in cleaner entry and reduced tearing of the wood surface. The bit’s sturdy construction ensures stability during straight drilling and helps preserve edge sharpness for repeated use. Available in multi-packs for workshop or site use, it supports efficient workflow when multiple holes of the same diameter are needed.

Suitable for

• Drilling deep, straight holes in softwoods and hardwoods
• Timber framing and carpentry work
• Door and window frame installation and joinery
• Electrical and plumbing rough-ins through wooden members
• Furniture assembly and on-site woodworking tasks

Key specifications

• Diameter: 14 mm
• Overall length: 230 mm
• Type: spiral auger / wood bit with screw point
• Flute: twisted spiral for chip removal
• Material and finish: hardened steel construction suitable for wood drilling

How to use

Select an appropriate drill or brace that accepts the shank of the auger bit. Mark the drilling point on the workpiece and, if precision is required, use a pilot mark or centre punch. Start drilling at low speed to allow the screw tip to engage and self-feed, then increase speed as the bit advances. Apply steady, moderate pressure; allow the screw tip and flutes to draw the bit into the wood rather than forcing it. Periodically withdraw the bit to clear chips when drilling long holes to prevent overheating and binding.

Usage recommendations

Use cutting lubricant or occasional clearing when drilling resinous or very hard woods to reduce heat and prolong bit life. Ensure the drill’s chuck and operator technique keep the bit aligned for straight holes; replace the bit if the cutting edges become dull to maintain clean hole quality.
