The Diamond Core Drill Bit DX High Speed Dry with a 1.1/4 inch UNC thread mount is designed for dry drilling. With a maximum usable length of 330 mm, the diamond core bit can create holes with a diameter of 37 mm. The uniform use of the entire diamond segment and the extended lifespan of the core bit are achieved through the innovative 3D diamond matrix. Dry drilling generates less mess and allows for more efficient work, even in locations without a water supply. The over-twisted core bit reduces wear, and the core bit is very cutting-friendly.
