The Silver 450 core bit is ideal for medium and large hole diameters. This core bit is mounted on wet machines with 1”1/4 fitting. Completely similar to the Gold 450 core bit, the difference lies essentially in the body, which in this case is perfectly cylindrical. 450 mm long, available in diameters from 32 to 1000 mm. To use every diameter to the highest performance, it is decisive to have a machine with the power output and rpm suited to that diameter.
