Rounding over bit KWB 754020 Shank diameter 8 mm

The KWB 754020 rounding over bit has an 8 mm shank diameter and a tungsten carbide tipped cutting head designed to produce smooth, rounded edges on wood, boards and suitable plastics. It is built for use in standard hand-held routers and provides precision for finishing work such as edge rounding, profile trimming and preparing joints.

Advantages

The carbide tip and precision-ground cutting edges deliver long-lasting sharpness and consistent results. Its two-cutter design reduces tear-out and ensures clean, smooth cuts on both hard and softwoods as well as on composite boards and some plastics. The 8 mm shank offers firm grip in common router collets, improving stability during use.

How to use

Mount the KWB 754020 rounding over bit securely in the router collet with the 8 mm shank fully inserted and tightened according to the router manufacturer’s instructions. Set the router speed appropriate for the material (lower speeds for hard materials), make a test cut on scrap, then guide the router steadily along the workpiece edge with even feed pressure to achieve a uniform rounded profile. For best results, take multiple shallow passes rather than removing too much material in a single pass.

Recommendations

Use appropriate personal protective equipment, secure the workpiece, and ensure the router is switched off before changing the bit. Clean and inspect the carbide tip regularly and avoid prolonged use at excessive speed to extend tool life.
