The Bosch PRO SDS Max-4 Masonry Drill Bit in 18mm diameter with a total length of 940mm is a robust choice for drilling medium-to-large holes in reinforced concrete. The 18mm diameter is well suited to conduit runs, fixings, and structural penetrations where a precise, clean bore is essential. Lasting up to 1.5x longer than a Bosch SDS max-2 drill bit, this variant is built for demanding professional use. Its 4-cutter tungsten carbide head powers through reinforced concrete without jamming or snapping when it encounters rebar, protecting both the bit and the operator's workflow. The deep-channel fluting efficiently evacuates dust and debris even at this larger diameter, keeping the hole clean and the bit cool for sustained performance.
