Constructed with laser-welded diamond segments, this bit ensures consistent cutting performance when working with brick and concrete blocks in dry cutting applications. The 1/2" BSP threaded arbor connection provides the secure mounting necessary for controlling larger diameter core bits safely and accurately.
