Dry Diamond Core Drill Bit 78mm

The CorePlus 78mm Diamond Dry Core Drill Bit provides excellent capability for large-diameter drilling operations in masonry, concrete, and stone materials. This substantial 78mm diameter makes it particularly well-suited for significant installation work, including large-bore pipework, major ventilation ducting, grouped utility services, or creating substantial access points for building services. Engineered with 8mm diamond segments that deliver a high concentration of premium-grade diamond in the bond, this core bit utilises advanced diamond/metal bonding metallurgy for exceptional durability and extended service life. The ribbed core body works in conjunction with V-groove segments to enable fast clearing of debris, maintaining continuous fast cutting action throughout demanding operations, while the aerated core design enhances cooling and prolongs core life. The 1/2in BSP threaded connection ensures compatibility with standard core drilling machines and accessories, making this a reliable choice for professional contractors undertaking larger-scale drilling projects.
