Concrete-Granite Drill Bit

The kwb concrete-granite drill bit is perfect for the hardest materials such as granite, slate, concrete and ceramics. The diamond-ground hard metal cutting edges made of high-grade tungsten carbide guarantee precise drill holes and a long lifetime. An asymmetrical spiral ensures effective drill dust removal, while the optimised geometry reduces the energy consumption of the drill. Without impact function, the drill bit ensures clean results at 800–1000 rpm. Suitable for cordless and corded machines, it is a reliable tool for DIYers and professionals.
