【Ideal Application】This diamond coated core drill bit removes a complete circle from glass, marble, tiles, granite, ceramic or other. They are perfect for drilling glass, tile bottles, block jars, fiberglass porcelain tile ceramic, slate Mable, granite light stone, etc.
【Super Material】These diamond drill bits are made of durable high-speed steel and have a long service life.
【Sharp & Smooth Cut】Coated with high-quality diamond, the diamond hole saw creates a high precision, smooth cut with no broken edges. Reduces drill speeds, low drill pressure, and increased use of water lubrication will extend drill bit life considerably.
Note: When using the diamond drill bits, please use lubrication (water); otherwise, the diamond core drill will burn. Do not use the drill bits on concrete or for depths beyond about 1/2". Also, start your hole diagonally by making a round trace, and then hold drill straight.
