The diamond-tipped drill bit is ideal for fast, fine drilling in concrete, masonry and stone (e.g. concrete slabs, kerbstones and similarly hard types of stone). Thanks to its robust design, it offers an extremely long service life. With a possible cutting depth of 65 mm and availability in various diameters, it is suitable for setting flush-mounted sockets (junction box and socket inserts). The external transport auger allows the drilling dust to be reliably removed and prevents the drill bit from clogging. You can easily remove the drill core via the 2 large ejection slots. The drill bit is TÜV-certified - so you can rely on a safe, high-quality product.
