This tungsten carbide tipped annular bit including mandrel with specially hardened 110 mm long SDS Plus shank, made in Germany, is especially suitable for use with hammer drills. The specially soldered heat-resistant carbide plates are extremely durable and let you drill materials such as concrete, brick walls and stone with ease (e.g. concrete slabs, kerbstones and similar types of hard stone). With a possible cutting depth of 46 mm and a selection of diameters, the annular bit is ideal for house construction, extension and conversion projects. A centring drill bit (Ø 8 mm) with a length of 70 mm helps you to position your drilled hole exactly. It features a user-friendly pin solution for removal and changing without tools. To enable you to get going straight away, the hole saw comes pre-assembled. The annular bit is TÜV-tested, meaning you can be sure of a safe, quality product.
