Draper Diamond Core Bit

This 52 x 170mm diamond core bit is perfectly sized for 40mm and 50mm waste pipe installations, extractor fan ducting and larger electrical service entries. The 52mm diameter is particularly valuable for bathroom and kitchen installations where adequate clearance for waste pipework and good falls are essential for proper drainage. The laser-welded diamond segment construction delivers professional-grade durability when working with brick and concrete blocks in dry cutting applications. Compatible with all 1/2" BSP threaded arbors, this bit mounts securely to core drilling machines, ensuring accurate hole placement even in demanding positions. The 170mm length provides sufficient depth for most standard wall constructions, making it a practical addition to any plumber's or builder's core bit collection.
