Product Description
Milwaukee 3/16 in. x 6 in. MX4 SDS+ Carbide Drill Bits — 15 Pack
Model Number: 48-20-7911
The Milwaukee 48-20-7911 is a 15-pack of 3/16 in. diameter x 6 in. flute length x 8 in. overall length MX4 SDS+ Carbide Drill Bits — a value-pack quantity of Milwaukee's premium four-cutter SDS+ bits for the 3/16 in. anchor drilling diameter used extensively in commercial construction for light-duty concrete screw anchors and expansion fasteners. The MX4 four-cutter tip technology uses four active carbide cutting edges per revolution versus the two-cutter standard of conventional SDS+ bits, delivering faster penetration rate and distributing carbide wear across twice the surface area for extended bit life in hard commercial concrete where the four-cutter advantage is most pronounced. The 15-pack provides the production bit supply for commercial anchor installation crews who regularly install large quantities of 3/16 in. anchors and benefit from reduced per-bit cost compared to individual and 5-pack purchasing while maintaining the MX4 performance specification throughout the pack.
The 8 in. overall length extends the working reach beyond the standard 6 in. compact configuration — the additional length enables through-wall CMU penetrations, longer concrete screw embedments for higher pull-out ratings, and drilling positions where obstacles prevent the hammer from being placed close to the wall. At 3/16 in. diameter and 8 in. overall length, the flute specification is critical for maintaining effective concrete debris evacuation through the extended working depth — Milwaukee's helical flute geometry at this diameter provides adequate transport capacity for 3/16 in. bore debris over the 6 in. flute length, keeping the hole clear and drilling speed consistent throughout production anchor installation runs. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during continuous production drilling.
