The Diamond Core Drill Bit DX High Speed Dry with a 1.1/4 inch UNC thread mount is suitable for dry drilling. With a maximum usable length of 330 mm, the diamond core drill can create holes with a diameter of 82 mm. The uniform use of the entire diamond segment and the extended lifespan of the drill bit are achieved through the innovative 3D diamond matrix. Dry drilling generates less mess and allows for more efficient work, even in areas without a water supply. The over-twisted drill bit reduces wear and is very cutting-efficient.
