Diamond Cutter Strend Pro is designed for enlarging, deburring, and beveling existing holes in hard tiles, ceramics, glass, and marble. It is not intended for drilling new holes. Cleaned holes reduce the risk of later cracking of tiles, glass, or marble. The cutter is recommended to be used in an up-and-down motion to utilize the entire height of the cutter, ensuring proper cooling. It is used for dry cutting in an angle grinder (M14 thread).
