Dry Diamond Core Drill Bit 22mm

The CorePlus 22mm Diamond Dry Core Drill Bit is perfectly sized for precision drilling applications in masonry, concrete, and stone. This compact 22mm diameter makes it ideal for smaller installations such as electrical cable runs, narrow pipework, fixing bolts, or creating access holes for sensors and light fittings. This variant features a convenient 10mm hex shank design, which means it does not require an arbor accessory, allowing for quick and easy attachment to compatible power tools. Despite its compact size, it features 8mm diamond segments with a high concentration of premium-grade diamond in the bond, utilising leading-edge diamond/metal bonding metallurgy for long-lasting performance. The ribbed core body and V-groove segments enable fast clearing of debris, whilst the aerated core design enhances cooling and extends core life. The 10mm hex shank provides excellent grip and stability during operation, making this an essential addition to any electrician's or general tradesperson's toolkit.
