Product Description
Milwaukee SDS+ Bit 3/16 in. x 8 in. x 10 in.
Model Number: 48-20-7413
The Milwaukee 48-20-7413 is an SDS+ rotary hammer drill bit in 3/16 in. diameter with an 8 in. working length and 10 in. overall length — the standard extended-length configuration for the 3/16 in. light anchor diameter providing working reach for through-wall CMU penetrations and deeper anchor embedments beyond the compact 6 in. overall configuration. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with optimized fluting for concrete drilling performance. At the small 3/16 in. bore and 8 in. working depth, Milwaukee specifically engineers the flute geometry to maintain effective concrete debris transport from the deep hole base without choking — the limited flute cross-section of a small-bore bit must handle chip evacuation over extended depth, requiring careful pitch calibration for this diameter-length combination.
The 10 in. overall length enables drilling through standard 8 in. CMU block with light finish material, longer concrete screw anchor pilot holes where pull-out ratings require deeper pilot holes, and positions where the hammer must be held back from the drilling face due to ceiling clearance or adjacent structure. The 3/16 in. diameter is the standard pilot hole for light-duty concrete screw anchors and small expansion fasteners throughout commercial construction. For production-volume anchor installation at this length, Milwaukee offers 25-pack bulk format for significantly lower per-bit cost than individual purchasing. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers.
