Vacuum Brazed Diamond Core Drill Bits are very aggressive ideal for drilling glass, ceramic and porcelain tiles leaving smooth edges without chipping. Vacuum brazed technology is superior to electroplating in that the bits last much longer than electro-plated diamond bits. The main working parts of Diamond core drill bits - drilling segments are made of Diamond-based formula, and superior grade diamond to match, we can also adjust the segment formula to match different kinds of stone, ceramic and concrete etc
High efficiency, Higher grade diamond with a specific bond bring the operators a fantastic experiences of fast cutting
2. Sizes of adaptor for threaded bits: M14, 5/8"-11, 1/2" BSP, 1/2" GAS
3. Applicable and stable function&performance for drilling of brick wall, concrete, reinforced concrete, Granite, Marble, Ceramic, Quartz etc
4. Suitable for hand held drill motor and stand mounted motors
5. Different Formulas for different materials and working situations
