The carbide-coated core bit, including a mounting disc and centring drill bit, 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. In combination with the separately available mandrel (item 3862000), the drill bit is also suitable for deep holes and breakthrough holes thanks to its multiple consecutive holes. It can be quickly locked in the chuck of your drill using the hexagonal shank. A centring drill bit (Ø 8 mm) makes it easier for you to position your drill hole precisely. The core bit is supplied pre-assembled so that you can get started straight away. The drill bit is TÜV-tested - so you can rely on a safe, high-quality product.
