Draper Diamond Core Bit

This 152 x 170mm diamond core bit represents the largest diameter in the range, designed for major building services installations, substantial ventilation systems and significant structural penetrations. The 152mm diameter is particularly valuable in commercial, industrial and infrastructure projects where large clearances are essential for major services, substantial ductwork or future-proofing installations. Constructed with robust laser-welded diamond segments, this bit delivers reliable performance when dry cutting through brick and concrete blocks in demanding professional applications. The 1/2" BSP threaded arbor connection provides secure mounting on heavy-duty core drilling equipment, ensuring controlled and accurate operation even at this substantial diameter. The 170mm length offers practical drilling depth for single-aspect operations, making this an essential tool for mechanical and electrical contractors working on major installations.
