Product Description
Milwaukee SDS+ Bit 3/16 in. x 6 in. x 8 in.
Model Number: 48-20-7412
The Milwaukee 48-20-7412 is an SDS+ rotary hammer drill bit in 3/16 in. diameter with a 6 in. working length and 8 in. overall length — the extended-length individual unit configuration for the 3/16 in. anchor drilling diameter, providing additional working reach versus the standard 4 in. working length for applications where through-wall CMU penetrations or longer concrete screw embedments require more depth. The 3/16 in. diameter is the standard pilot hole size for light-duty concrete screw anchors and small expansion fasteners used throughout commercial construction for conduit support brackets, equipment mounting, and general concrete fastening. The 8 in. overall length with 6 in. flute enables through-wall drilling in standard CMU block, longer anchor embedments for applications where pull-out load specifications require extended concrete screw lengths, and drilling positions where the hammer must be held back from the wall surface due to adjacent structure.
Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized helical fluting that maintains efficient concrete debris evacuation through the full 6 in. working depth for sustained production drilling speed without hole choking. The individual unit format is the right purchasing option for single-bit replacement or for contractors who use the 8 in. extended length for specific project requirements without needing bulk-pack quantities of the extended length. For high-volume anchor installation at this diameter and length, Milwaukee offers the 25-pack bulk format that reduces per-bit cost significantly for production-pace commercial installation crews. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during drilling.
See Milwaukee's complete 44 Magnum SDS+ catalog for all available configurations at the 3/16 in. diameter including standard and extended lengths in bulk packs.
