Holds up to 2x longer than a standard diamond hole saw. Drilling a good hole in hard tiles, stone, or even glass can be 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 particles on the continuous edge allow for angled cutting without the need for a guide. The PRO Tile offers an extremely effective design and good durability. The solder joints between the grit and the body are strong. The deep-set heat slots dissipate unwanted heat buildup, ensuring long-lasting performance. Designed for use with Bosch's Power Change Plus quick-change adapter for accuracy and robustness.
