About this item
- 【Premium Brazed Diamond Technology】Crafted from high-strength steel with industrial diamond grit, this set delivers exceptional durability. The advanced brazing process ensures maximum corrosion resistance, while the thickened tungsten carbide coating provides superior cutting performance for precise, smooth, and stable drilling.
- 【Chip-Free Precision Holes】Engineered with a reinforced diamond layer, these hole saws create razor-sharp edges and clean, flat-bottomed holes without cracking or chipping. Perfect for tiles, ceramics, glass, marble, granite and terrazzo.
- 【Dual Use for Wet and Dry Drilling】 Our brazed diamond hole saw has been specially treated with high-temperature resistance, allowing it to be used for dry drilling directly without adding water as a coolant. However, to extend the service life of the diamond drill bit, it is recommended to add water or other coolants during the drilling process.
- 【Kit Includes】 : Our 9-piece diamond hole saw set includes: 22, 28, 35, 44, 68, 73 mm hole saws; 1 mandrel for 22 mm and 28 mm hole saws, 1 mandrel for 35-44-68-73 mm hole saws, 1 hex key, all in a blow-molded carrying case.
- 【Versatile Applications】With 25mm cutting depth, ideal for ceramic tiles, porcelain, granite, marble, stone, masonry, and brick. The complete kit solution for all your drilling needs.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
