Product Description
Milwaukee SDS+ Bit 3/16 in. x 10 in. x 12 in.
Model Number: 48-20-7414
The Milwaukee 48-20-7414 is an SDS+ rotary hammer drill bit in 3/16 in. diameter with a 10 in. working length and 12 in. overall length — the deep-reach extended-length configuration of the 3/16 in. SDS+ bit for through-wall CMU penetrations and longer concrete screw embedments that the standard 6 in. and 8 in. configurations cannot achieve. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized helical fluting for the specific challenge of small-diameter deep drilling — maintaining effective concrete debris evacuation through the 10 in. working depth at 3/16 in. diameter requires careful flute pitch and geometry optimization since the limited flute cross-section at this small bore must transport debris over the extended working depth without choking. Milwaukee engineers the flute specification specifically for this diameter-length combination to keep debris moving continuously from hole base to surface throughout production drilling.
The 12 in. overall length enables through-wall drilling in standard CMU block construction, longer concrete screw anchor installations where pull-out load specifications require greater embedment depth than the 6 in. working length provides, and drilling positions where the hammer must be positioned back from the wall due to structural elements that prevent close placement. This is the standard individual unit purchasing format for contractors who need a specific replacement or who use this extended-length configuration for defined applications without requiring 25-pack bulk quantities. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during production drilling operations.
Available in 25-pack bulk format for high-volume use — see Milwaukee's complete 44 Magnum SDS+ catalog for all pack quantities at the 3/16 in. diameter and 12 in. overall length.
