Product Number: 43712
Diamond core drilling through brick, concrete blocks and other masonry demands a bit engineered specifically for dry cutting — and this 78 x 170mm Draper diamond core drill bit meets that requirement without the need for water suppression or hammer action. It is well established across the plumbing, electrical and general building trades, where precise, clean-edged core holes are required in most masonry applications. The bit connects to all 1/2" BSP threaded arbors, making it compatible with a wide range of professional core drilling machines. Five laser-welded diamond segments provide the cutting performance, with each segment standing 8mm tall to deliver consistent material removal across the 78mm diameter cutting face. The overall length of 170mm accommodates a cutting depth of 150mm, suited to full-thickness masonry walls and block courses commonly encountered on site. It is important to note that this bit must not be used in hammer mode. Operation in hammer mode risks damage to the laser-welded segment connection and may compromise both tool and bit integrity. Dry cutting without hammer action is the correct and only recommended operating method for this product. The 43712 is supplied as a single 78 x 170mm diamond core drill bit, ready for use with a compatible 1/2" BSP arbor. For contractors and tradespeople requiring a reliable dry-cut core bit in a widely used diameter, this Draper offering covers the most common masonry coring tasks encountered across building and installation work.
Designed for dry cutting and suitable for use on most masonry applications, including brick and concrete blocks, this 78 x 170mm diamond core bit is popular for use in the plumbing, electrical and general building trades. The bit is compatible with all 1/2" BSP threaded arbors and has a laser-welded diamond segment connection. It should not be used in hammer mode.
