Draper Diamond Core Bit

This 117 x 170mm diamond core bit delivers a substantial diameter for large-scale building services, major ventilation installations and significant structural penetrations. The 117mm size is particularly suited to commercial and industrial applications where ample clearance is needed for bundled services, large diameter ductwork or major pipe installations. The laser-welded diamond segment construction provides the durability required for demanding commercial applications when dry cutting through brick and concrete blocks. With its 1/2" BSP threaded arbor connection, this bit mounts securely to professional core drilling equipment, ensuring safe and accurate operation at this larger diameter. The 170mm length offers practical depth for most single-aspect drilling operations whilst maintaining controllable weight characteristics.
