The Bosch PRO SDS Max-4 Masonry Drill Bit in 35mm diameter with a total length of 920mm is purpose-built for professionals who need to drill wide, accurate holes in reinforced concrete. The 35mm size suits large anchor bolts, oversized pipe sleeves, and heavy-duty structural penetrations on demanding commercial and civil engineering projects. Lasting up to 1.5x longer than a Bosch SDS max-2 drill bit, this variant is engineered for the long haul. Its 4-cutter tungsten carbide head handles the extreme stresses of large-diameter reinforced concrete drilling, resisting both jamming and breakage when rebar is struck. The deep-channel fluting is especially effective at this size, efficiently clearing the high volume of dust and debris to keep performance consistent throughout extended use.
