This Bosch PRO Break Through SDS Max Masonry Drill Bit is the 80mm diameter, 1000mm length variant — the largest and longest configuration in the range. It is engineered for the most demanding through more→-drilling tasks, where both maximum hole diameter and extended reach are required, such as core drilling through thick reinforced concrete walls, deep floors, or structural slabs. The 3-cutter tip is produced from vacuum-brazed, hardened high-quality tungsten carbide to sustain performance at this scale. With a 1000mm working length and 80mm diameter generating a high volume of debris, the U-shaped body, twin flutes, and tapered shank play a vital role in continuously evacuating dust and broken ma…
