Annular Bit Insert, Tungsten Carbide Coated

The tungsten carbide coated annular bit insert is especially suitable for drilling holes with a power drill or cordless screwdriver in brick walls and stone (e.g. pumice stone, aerated concrete or similar types of soft and medium-hard stone). With a possible cutting depth of 55 mm and a selection of diameters, the insert is ideal for building projects or renovations. It is compatible with the separately available receptacle plate (art. no. 3472000/3466000) and centring drill bit with hexagon shank (art. no. 3471000). It is also TÜV-tested, meaning you can be sure of a safe, quality product.
