The carbide-coated core bit insert is especially suitable for drilling with a drill or cordless screwdriver in masonry and stone (e.g. pumice stone, aerated concrete or similar soft and medium-hard types of stone). With a possible cutting depth of 55 mm and availability in various diameters, it is ideal for construction projects or renovations. It is compatible with the separately available mounting disc (item no. 3472000/3466000) and centring drill bit with hexagonal shank (item no. 3471000). The core bit insert is TÜV-tested - so you can rely on a safe, high-quality product.
