Professional diamond router bit for marble, granite, travertine, engineered stone, and tile – creates bullnose edge profile on countertops, shower curbs, and stone shelves.
1/4 inch shank fits standard drills and routers. R6 (6mm) bullnose radius produces smooth, consistent edge on natural and engineered stone.
Vacuum brazed diamond construction for strong durability and long-lasting sharpness. Maintains cutting performance after repeated use on multiple tiles or stone slabs.
For best results, use with water. Light water mist is recommended to cool the bit, reduce chipping, and extend tool life – especially on hard stone materials.
Creates clean radius profile on stone edges. The finish can be easily refined with light sanding for a polished look.
