The Bosch PRO SDS Max-4 Masonry Drill Bit in 40mm diameter with a total length of 920mm represents the largest option in the range, delivering exceptional capability for wide-bore drilling in reinforced concrete. At 40mm, this variant is suited to the most demanding structural penetrations, large-diameter service runs, and heavy anchor applications found on major construction and civil engineering projects. Lasting up to 1.5x longer than a Bosch SDS max-2 drill bit, it's engineered to withstand the most punishing drilling conditions. The 4-cutter tungsten carbide head powers through reinforced concrete at this extreme diameter without jamming or breaking when rebar is encountered. Deep-channel fluting is critical at this scale, and it delivers — efficiently evacuating the large quantities of dust and debris to maintain cutting performance and extend bit life.
