Kovametalli-muurauspora 9,0 mm, työpituus 61 mm, kokonaispituus 103 mm, sylinterikara

On a busy construction site, a professional installer needs to anchor a heavy bracket into a concrete wall. With this 9.0 mm carbide masonry drill bit, the task is straightforward: the two-cutter tungsten carbide tip bites into the hard surface, while the spiral flutes clear dust efficiently, leaving a clean hole ready for the anchor. The bit’s 61 mm working length is ideal for standard wall thicknesses, and its 103 mm total length provides a secure grip in the drill chuck. Built from hardened high-carbon steel with a carbide tip, it withstands the demands of repeated drilling in concrete, brick, and stone. Whether using a rotary drill or a hammer drill in rotary mode, this bit delivers consistent performance.
