The KWB 511100 countersink drill bit set contains three single-flute, 90° carbon steel countersinks designed to create conical recesses for flush-fitting countersunk screws in wood and non-ferrous metals. The set is supplied in a blister pack that protects the tools and keeps them organized for transport and storage.

Advantages

Made of carbon steel with a single-flute geometry and a 90° cutting angle, these countersinks produce a clean conical seat for screws and are suitable for both wood and non-ferrous metal work. The three-piece set covers common sizes and the blister packaging ensures easy storage and visibility of the bits.

How to use

Mark the screw position and secure the workpiece. Use a drill or drill press with appropriate speed for the material, clamp the countersink bit in the chuck and carefully drill to the required depth so the screw head sits flush with the surface. For metal, use cutting fluid where appropriate and apply steady, moderate pressure to avoid overheating.

Recommendations

Choose the correct countersink size to match the screw head and test on scrap material before final drilling. Keep the bits clean and store them in the blister pack to prevent damage. For prolonged life when working with metal, control speed and use coolant as needed.
