TCT Tipped Corner Rounding Router Cutter Bit With Bearing

The Rennie Tool TCT Tipped Corner Rounding Router Cutter Bit With Bearing is designed for producing smooth, consistent rounded edges and corner profiles on timber, MDF, plywood and other suitable woodworking materials.

Featuring precision-ground Tungsten Carbide Tipped (TCT) cutting edges, these router cutters provide excellent cutting performance and durability for both professional and general woodworking applications.

The integral guide bearing follows the edge of the workpiece, helping maintain a consistent cutting profile without requiring a separate guide or template. This makes the cutter ideal for rounding over square edges, softening sharp corners and creating clean decorative edge profiles.

Available in a wide range of sizes, allowing you to select the appropriate cutting radius and dimensions for your application.
