Product Description
Milwaukee SDS+ Bit 1/2 in. x 10 in. x 12 in.
Model Number: 48-20-7474
The Milwaukee 48-20-7474 is an SDS+ rotary hammer drill bit in 1/2 in. diameter with a 10 in. working length and 12 in. overall length — the extended deep-reach configuration at one of the most heavily used commercial anchor diameters for through-wall CMU drilling and deeper structural anchor embedments requiring more working depth than the standard 6 in. and intermediate 10 in. overall configurations. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized helical fluting for consistent concrete drilling performance across the 10 in. working depth. The 12 in. overall length enables through-wall penetrations in standard 8 in. CMU block with substantial finish material, longer concrete screw anchor pilot holes where pull-out load specifications require greater embedment than standard configurations provide, and drilling positions where surrounding structure prevents the hammer from being placed close to the drilling face.
The 1/2 in. diameter covers pilot holes for 3/8 in. wedge anchors, sleeve anchors, and drop-in anchors used throughout commercial construction for structural equipment mounting, conduit support, and the full range of medium-duty anchor fastening applications. At the 1/2 in. diameter and 12 in. overall length, Milwaukee's flute engineering maintains effective concrete debris transport from the base of the 10 in. deep hole throughout production drilling without the choking that would interrupt pace and require repeated hole-clearing. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers. Available in bulk pack formats for high-volume production purchasing.
See Milwaukee's complete 44 Magnum SDS+ catalog for all available lengths and pack quantities at the 1/2 in. diameter.
