The DX HIGH SPEED Dry diamond core bit with 1.1/4 inch UNC thread is suitable for dry drilling. With a maximum working length of 330 mm, the diamond core bit can drill holes with different diameters. The innovative 3D diamond matrix ensures that the entire diamond segment is used evenly and at the same time extends the service life of the core bit. Dry drilling causes less dirt and at the same time ensures more efficient work even in places where there is no water supply. The over-twisted drill bit reduces wear and the drill bit is very easy to cut.
