This carbide-tipped drill bit including mandrel with a specially hardened 110 mm long SDS-plus shank is especially suitable for use with a hammer drill. You can drill materials such as concrete, masonry and stone (e.g. concrete slabs, kerbstones and similarly hard types of stone) with ease thanks to the specially soldered, heat-resistant carbide plates and benefit from a long service life. With a diameter of 68 mm and a possible cutting depth of 46 mm, it is ideal for setting electrical flush-mounted sockets. A centring drill bit (Ø 8 mm) with a length of 70 mm makes it easier for you to position your drill hole precisely. The drill 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.
