Product Description
Milwaukee 7/16 in. x 12 in. MX4 SDS+ Carbide Drill Bit
Model Number: 48-20-7364
The Milwaukee 48-20-7364 is a 7/16 in. diameter x 10 in. flute length x 12 in. overall length MX4 SDS+ Carbide Drill Bit — the extended deep-reach configuration of Milwaukee's premium four-cutter MX4 bit at the 7/16 in. anchor diameter for through-wall penetrations and deeper embedment applications. The MX4 four-cutter tip provides four active carbide cutting contacts per revolution, delivering faster penetration rate and extended bit life from doubled carbide wear distribution compared to the standard two-cutter geometry. The 12 in. overall length enables through-wall drilling in standard CMU block construction, longer concrete screw anchor embedments where pull-out load specifications require greater depth, and drilling positions where surrounding structure prevents placing the SDS+ hammer close to the drilling face. Milwaukee's optimized flute pitch and geometry for this configuration maintains effective concrete debris evacuation through the full 10 in. working depth for uninterrupted production drilling at this diameter-depth combination.
The 7/16 in. diameter sits between the more common 3/8 in. and 1/2 in. anchor sizes, serving specific structural fastening applications where engineering specifications call for 7/16 in. anchors for medium structural connections. At 12 in. overall length, the MX4 four-cutter advantage is compounded — the extended drilling time per hole in hard commercial concrete increases the cumulative benefit of faster penetration rate and reduced carbide wear per inch of depth drilled. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during production anchor installation operations on commercial projects.
