## Summary description

GEKO G38127 is a 40 mm wood borer (knot driller) designed for removing knots and defects from timber.

## Long description

GEKO G38127 is a 40 mm wood borer (knot driller) designed for efficient removal of knots, resin pockets and localized defects from solid timber and beams. Supplied as a pack of 50 cutters, this accessory fits standard woodworking drill chucks and is intended for use prior to planing, jointing or finishing to improve surface quality and reduce wear on planing blades. The cutters are suitable for preparatory timber work in carpentry, joinery and structural timber processing.
Advantages
The 40 mm diameter provides a balance of material removal and accuracy for common knot sizes, while the pack of 50 ensures continuity of work without frequent tool changes. Designed for compatibility with standard drilling tools, these knot drillers streamline defect removal and help achieve more consistent results when preparing boards and beams for subsequent machining. Using dedicated knot cutters reduces tearing and scoring in planing operations and contributes to longer service life for downstream cutters.
Suitable for
Removing knots and localized defects from softwood and hardwood timber
Preparing timber surfaces before planing, jointing or sanding
Carpentry and joinery workshops handling dimensional lumber
On-site timber repair and structural timber preparation
Key specifications
Cutting diameter: 40 mm
Pack quantity: 50 pieces
Intended material: solid timber (softwood and hardwood)
Tool compatibility: standard drill chucks and woodworking drilling tools
Main function: removal of knots, resin pockets and localized defects
How to use
Fit the wood borer into a suitable drill or drilling attachment designed for woodworking, ensuring the cutter is securely clamped in the chuck. Mark the area of the knot or defect on the timber, align the cutter perpendicular to the work surface and drill at a controlled speed to remove the defect to the desired depth. After cutting, clean the hole and, if required, fill or level the removed area prior to planing or finishing. Replace cutters from the pack as they become worn to maintain clean removal and consistent results.
Usage recommendations
Use appropriate personal protective equipment, including eye protection and dust extraction where possible. Choose a drilling speed that prevents burning and excessive vibration. Test on scrap timber to determine optimal depth and feed rate for the specific wood species before working on final pieces.
