Product Description
Milwaukee SDS+ Bit 1/2 in. x 8 in. x 10 in.
Model Number: 48-20-7473
The Milwaukee 48-20-7473 is an SDS+ rotary hammer drill bit in 1/2 in. diameter with an 8 in. working length and 10 in. overall length — the extended-length configuration for one of the most heavily used commercial anchor sizes, providing additional working depth versus the standard 6 in. configuration for through-wall CMU penetrations, deeper structural anchor embedments, and drilling positions where the standard length cannot complete the required hole depth. 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 the widest range of structural and equipment mounting applications — it is among the most commonly drilled SDS+ bit diameters on commercial projects. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized helical flutes that maintain efficient debris evacuation through the full 8 in. working depth for consistent production drilling speed.
The 10 in. overall length with 8 in. working depth enables through-wall drilling in standard 8 in. CMU block construction, longer concrete screw anchor embedments where pull-out load specifications require greater depth than the standard 4 in. working length provides, and drilling positions where the hammer must be positioned further from the wall surface due to structural elements that prevent close placement. At the heavily used 1/2 in. diameter, the extended-length configuration is a practical option for commercial projects where both standard-depth and extended-depth holes at the same diameter are required — having the extended-length bit handles both needs without bit changes for applications that fall within the 8 in. working depth. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during production anchor installation.
Available in 25-pack bulk format 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.
