• 1. Dry drilling without water, 6mm-12mm drill bit, with wax inside, helps to cool the drill bit.
• 2. Widely used in drilling ceramic tiles, granite, marble and stone. ....
• 3. The working life of vacuum brazing technology is much longer than that of electroplating technology (usually 3-5 times that of electroplating technology).
• 4. Less debris, minimum breakage, less heat generation and better surface quality.
• 5. High diamond exposure rate provides faster and more active drilling for drilling holes in marble, ceramic tiles, granite, pebbles, walls and other materials.
