Holds up to 2x longer than a standard diamond hole saw. Drilling a good hole in hard tiles, stone, or even glass is a tricky task, even for professionals. However, with your skills and the PRO Tile hole saw, this problem is a thing of the past. The high-quality diamond grains on the continuous edge allow for angled cutting. You don't even need a guide for this. The PRO Tile offers an extremely effective design and good durability. The solder joints between the grains and the body are strong. The deeply set heat slots dissipate unwanted heat build-up and ensure long-lasting performance. Designed for use with Bosch's Power Change Plus quick-change adapter: for accuracy and robustness.
