The DX High Speed Dry diamond core drill bit 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 112 mm. The even utilization of the entire diamond segment and the extended lifespan of the core drill are achieved through the innovative 3D diamond matrix. Dry drilling generates less mess and allows for more efficient work in areas without water supply. The over-twisted core drill reduces wear and the drill bit is very cutting-friendly.
