Diamond Core Drill Bits are used for critically hard materials such as concrete, all natural & engineered stones, hard bricks, cured and reinforced concrete, cement and bricks. These are also used for tile and glass. These can be used for wet and dry drilling. Our drill bits offers very free drilling and high performance. These are available from 25 mm to 350 mm. The useful length of 350 mm and above makes the drill bits convenient for re tippling once the diamond segments are completely finished. We can also supply loose segment for core drill, as per specification.
