Wood Countersink Tool GEKO G38122, 15 mm Cutting Diameter, pack of 100

GEKO G38122 wood countersink tool with a 15 mm cutting diameter is designed for preparing timber and softwood surfaces before fastening or gluing. Supplied in a pack of 100, this countersink removes knots and surface imperfections, enlarges and chamfers drilled holes, and helps create clean, consistent recesses for screw heads. The tool is intended for use in woodworking, joinery and furniture repair where reliable, repeatable hole finishing is required.

Advantages

The 15 mm cutting diameter provides a standard recess size for many common screw heads, while the multipack supply of 100 pieces ensures availability for larger projects or production runs. The design allows quick removal of knots and smoothing of defects without over-enlarging the hole. The tool is compatible with typical hand drills and bench drills intended for woodworking, offering straightforward interchangeability and predictable results.

How to use

Secure the workpiece and mark the drilling point. Use an appropriate pilot drill to create a starting hole, then mount the countersink in the drill chuck. Align the countersink with the pilot hole and operate the drill at moderate speed, applying steady pressure until the required recess depth and chamfer are achieved. After use, clear wood chips from the cutting edges and check the finished recess for fit with the intended fastener.

Usage recommendations

When working with hardwoods or large-diameter pilot holes, reduce drilling speed and proceed gradually to avoid burning or excessive tear-out. Wear eye protection and follow standard workshop safety practices. Store the countersinks dry and clean to maintain cutting performance.
