Product Description
Milwaukee 1/2 in. x 12 in. MX4 SDS+ Carbide Drill Bit
Model Number: 48-20-7374
The Milwaukee 48-20-7374 is a 1/2 in. diameter x 10 in. flute length x 12 in. overall length MX4 SDS+ Carbide Drill Bit — the extended deep-reach MX4 configuration at the most heavily used commercial anchor diameter. The MX4 four-cutter tip delivers four active carbide cutting contacts per revolution versus the two-cutter standard of conventional SDS+ bits, providing faster penetration rate and extended bit life from doubled carbide wear distribution. The 12 in. overall length with 10 in. flute enables through-wall drilling in standard CMU block construction, deeper structural anchor embedments where pull-out load specifications require greater depth than the standard 6 in. configuration, and drilling positions where surrounding structure prevents placing the hammer close to the drilling face. Milwaukee's optimized flute pitch for this configuration maintains effective concrete debris evacuation through the full 10 in. working depth without choking that would interrupt production drilling pace.
At the 1/2 in. diameter — one of the most commercially significant anchor sizes — the MX4 extended-length configuration is particularly valuable on projects where both standard-depth and deeper anchor embedments are required at the same diameter, as one bit covers both requirements. The accumulated benefit of faster penetration rate and extended bit life across the many 1/2 in. anchor holes drilled in a commercial project scope makes the MX4 specification's cost premium easily recovered compared to standard two-cutter bits. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during production anchor installation.
See Milwaukee's complete MX4 SDS+ lineup for all available 1/2 in. configurations including individual, 5-pack, 10-pack, and 15-pack quantities.
