Product Description
Milwaukee SDS+ Bit 7/8 in. x 12 in.
Model Number: 48-20-7072
The Milwaukee 48-20-7072 is an SDS+ rotary hammer drill bit in 7/8 in. diameter with a 12 in. overall length — a large-bore extended-length configuration for structural anchor drilling and through-wall penetrations at the 7/8 in. diameter requiring working depth beyond the standard 6 in. configuration. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized helical fluting for concrete drilling performance. The 7/8 in. diameter serves specific structural anchor systems and specialty conduit fittings where this precise bore falls between the adjacent standard 3/4 in. and 1 in. sizes — engineering specifications for specific structural connections may call for the 7/8 in. pilot hole for the anchor hardware being installed at this intermediate size.
The 12 in. overall length provides the working depth for through-wall penetrations in thick structural concrete sections and for deeper structural anchor embedments where the standard 6 in. configuration's working depth is insufficient for the specified installation. At the 7/8 in. large bore and 12 in. extended length, Milwaukee's flute geometry must maintain effective debris transport throughout the full working depth — the combination of large bore and extended length generates substantial chip volume that the flute must continuously evacuate to prevent choking that would interrupt drilling pace on structural anchor installations. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers.
See Milwaukee's complete 44 Magnum SDS+ catalog for all available 7/8 in. configurations from standard through maximum extended lengths.
