The Strend Pro diamond router is designed for enlarging, finishing, and chamfering existing holes in hard tiles, ceramics, stoneware, glass, and marble. It is not intended for drilling new holes. Finished holes reduce the risk of later cracking of tiles, glass, or marble. We recommend routing upwards and downwards so that the entire height of the router is used, ensuring its cooling. It is used for dry routing in an angle grinder (M14 thread). Router O is 0-50 mm.
