Specification: Size: 42mm / 1.65". Suitable for cutting accurate holes on glass, ceramic, tile, porcelain, marble, stone bottles and pots. The spotting drill bit in the center helps for cutting accurate holes Diamond Tipped Drill Bits: Electroplated diamond is uniform and more wear-resistant. The hole saw achieves high precision and smooth cuts without edge breakage, with good toughness and high strength. Large Clearance Hole: The diamond hole saw with clearance hole facilitates the entry of cooling water and the escape of chips from the drilled hole. Makes the drilling process easier. The cutting is flat and smooth without scratches. Sharp & Smooth Cut: Diamond hole saw creates high precision, smooth cuts with no broken edges. White Zinc plating on the bits maximizes tool’s life with great resistance to corrosion Tips: Please use at low drill speeds and drill pressure. Always work with coolant (water) when drilling. Not suitable for drilling tempered glass, plastic and wood. Not suited for use on concrete or for depths beyond about 1/2". Descriptions:
1. Smooth and exact finish for lowering incision resistance and drill pressure, increasing the sharpness, and effectiveness of water lubrication.
2. Produce clean and accurate holes in minutes with little or no chipping. The positioning bit in the center helps for cutting accurate holes.
3. White Zinc plating on the bits maximizes tool's life with great resistance to corrosion. Excellent for making holes on glass or ceramic and considerably extending drill bit life.
4. Diamond drill bits along with clearance hole facilitate the entrance of cooling water and escape of chips and other particles from drilling. Makes drilling process easier.
5. Suitable for Stone, Tiles, Ceramics, Glass and etc Processing. Works better with a electric drill (Excluding in the item).
