Features: 

The tooth edge of the marble sintered hole opener is sharp, which is much more durable than the ordinary electroplated hole opener (glass drill). It can be used for drilling hard and brittle materials such as marble, ceramics, cement, ceramic tiles, etc. The holes are neat, smooth and free of broken edges, and will not produce vibration. The notch resistance is small, which improves the opening speed. After slotting, it is easy to decorate and chip removal.

Ideal application -this diamond coated core drill bit removes a complete circle from glass, marble, tiles, granite, ceramic or other.

Sharp & smooth cut - coated with high quality diamond, the diamond hole saw creates a high precision, smooth cut with no broken edges. 

The handle adopts triangle design, which makes the clamping more stable. It is suitable for electric hand drill, bench drill and other machines

Attention: Reduced drill speeds, low drill pressure and increased use of water lubrication will extend drill bit life considerably

Application: Porcelain，Ceramic，Granite，Marble，Stoneware，Quarry tiles，Slate，Terracotta，Terrazzo
