Drill Bit Set GEKO G38106 — wood bits 6 pcs, diameters 4–14 mm, length 300 mm

GEKO G38106 is a set of six wood drill bits with diameters from 4 mm to 14 mm and a working length of 300 mm. Designed for drilling clean, deep holes in timber and wooden elements, this set covers common hole sizes used for dowels, joinery, long-reach through-holes and structural fixings. The bits are intended for use with handheld drills and drill presses when extended reach and precise hole depth are required.

Advantages

The set provides a range of popular diameters so you can select the right bit for dowels and fasteners without changing tools frequently. The 300 mm working length enables drilling into thick elements and across assemblies where standard-length bits are too short. Bits designed for wood produce clean chip evacuation and reduced tear-out at exit points when used with appropriate speed and support. Compatibility with common drill chucks makes the set versatile for both manual and machine use.

Suitable for

• Drilling dowel holes in furniture and frames
• Creating through-holes in beams and boards
• Long-reach drilling in assembled components
• Use with handheld drills and drill presses

Key specifications

• Number of pieces: 6
• Diameter range: 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 14 mm
• Working length: 300 mm
• Intended material: wood and timber
• Shank type: round (compatible with standard chucks)

How to use

Choose the drill bit diameter that matches the dowel or fastener size. Secure the bit in the drill chuck and ensure it is tightly clamped. Mark the drilling location and, if necessary, use a stop collar or tape to control depth. Start drilling at moderate speed, applying steady feed pressure to maintain alignment. For through-holes, support the exit side to reduce splintering and, if required, finish the hole from the opposite side for a cleaner edge. Clean wood chips from the bit periodically to maintain cutting performance.

Usage recommendations

For best results, match drill speed to bit diameter and wood type: use higher speeds for softwoods and moderate speeds for hardwoods. Use proper clamping and backing supports to minimize tear-out. Inspect bits regularly for wear and replace when cutting performance declines.
