Drill bit GEKO wood auger G37418 — spiral auger 22 x 460 mm (pack 20/40)

Spiral wood auger GEKO G37418, diameter 22 mm and length 460 mm, is designed for drilling clean, deep holes in timber and wooden structures. The spiral flute efficiently evacuates chips while the sharp, pointed tip centers the bit for accurate starts and steady penetration. The auger profile maintains cutting stability and reduces binding, making it suitable for creating through holes and deep bores in beams, posts and boards. Compatible with hand braces and many power drills, this spiral auger is intended for use in carpentry, joinery and general construction.

Advantages

The spiral flute geometry ensures fast chip removal and consistent drilling speed, reducing clogging during deep boring. The centered pointed tip provides precise positioning and easier initiation of holes without pilot drilling in many cases. The long 460 mm length allows reaching through thick elements or creating deep recesses, while the 22 mm diameter delivers a balance between material removal and structural integrity. The bit is suitable for both manual and powered use where standard wood augers are needed.

Suitable for

• Drilling through holes in beams, posts and large timber
• Creating deep recesses for dowels, bolts or fasteners
• Carpentry and joinery repairs and installations
• On-site construction where long-reach drilling is required

Key specifications

• Type: spiral wood auger
• Material compatibility: timber and solid wood
• Diameter: 22 mm
• Overall length: 460 mm
• Tip: pointed centering tip for accurate starts
• Flute: twisted spiral for chip evacuation
• Drive compatibility: hand brace and compatible power drills

How to use

Secure the bit in a compatible chuck or brace before drilling. Mark the drilling point and position the pointed tip on the mark to start accurately. Apply steady, even pressure while maintaining alignment; allow the spiral flute to remove chips rather than forcing the bit. For powered drills, use low to medium speed and moderate torque to prevent overheating and reduce the risk of binding. Withdraw the bit periodically when drilling deep holes to clear chips and inspect the cutting edges.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and gloves. For best results in hard or resinous woods, ensure the bit is sharp and consider pre-drilling a small pilot or using incremental drilling to reduce stress on the tool and material. Store the auger dry and protected to prevent corrosion and maintain cutting performance.
