About this item
- 【Brazing Technology Strong and Sharp】: Diamond hole saw tile drill bit set is made of diamond integral steel, which is strong and durable. The surface adopts high anti-corrosion brazing process, and the top thickened tungsten carbide grit coating provides excellent cutting strength, achieving high precision and smooth cutting, and drilling is stable and fast.
- 【Sharp and Clean Holes】: This diamond tile core drill bit has a thicker diamond coating, which makes the edge of the groove sharper, and can cut precise flat-bottom holes on smooth surfaces without chipping, such as tiles, ceramics, glass, marble, granite and terrazzo.
- 【Dual Use of Wet and Dry Drilling】: Our brazed diamond hole saw has been specially treated with high temperature resistance, so it can be directly dry drilled without adding water as a coolant. But in order to extend the service life of the diamond drill bit, it is recommended to add water or other coolants during the drilling process.
- 【Hole Saw Kit Contents】: Our 9-piece diamond hole saw set includes 22, 28, 35, 44, 68, 73mm; 1 arbor for 22mm and 28mm hole saws, 1 arbor for 35-44-68-73mm hole saws, 1 Allen key, with a blow-molded carrying case.
- 【Wide Application】: The hole saw cutting depth is 25mm. Suitable for ceramic, tile, ceramic tile, granite, marble, stone, masonry or brick, the kit is suitable for drilling holes in all these materials.

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.
