Product Details

◆ These diamond drill bits are made of industrial grade carbon steel with nickel-plated coated body to resist corrosion. Diamond coating maximizes performance and retains a sharper cutting edge than traditional carbide or bimetal hole saw.
◆ Each diamond hole saw has a smooth and exact finish that lower the incision resistance and drill pressure, increases the sharpness, and effectiveness of water lubrication. Excellent for making clean and precise holes on glass or ceramic and considerably extending drill bit life.
◆ 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. Not suitable for drilling tempered glass, plastic and wood.
◆ Perfect for drilling glass, ceramics, porcelain, ceramic tile, porcelain tile, limestone, slate, marble, light stone and fiberglass. (Need to be used at a low speed; Always use lubrication (water) when processing , otherwise the hole saw will burn.)
◆ Diameter: 14-250
