Diamond core bit Strend Pro with a diameter of 65 mm is a tool designed for cutting circular holes into tiles, floor tiles, marble and granite. Thanks to the diamond-set crown, it allows clean and precise cuts in hard materials without the need for cooling fluid – this is so-called dry drilling.
The core bit is equipped with a M14 thread, which ensures compatibility with standard angle grinders with the same thread. Maximum allowed speed is 13 000 rpm, which ensures efficient work with proper tool setup. Cutting depth reaches 35 mm. The correct procedure for use includes applying the tool at a 45° angle at the beginning of the cut and then gradually levelling it to a vertical position – this procedure is shown directly on the product packaging.
The core bit is suitable for use on the following materials:
- Ceramic tiles and floor tiles
- Marble and natural stone
- Granite and other hard mineral surfaces
