Product Description
Milwaukee 5/16 in. x 6 in. MX4 SDS+ Carbide Drill Bit
Model Number: 48-20-7341
The Milwaukee 48-20-7341 is a 5/16 in. diameter x 4 in. flute length x 6 in. overall length MX4 SDS+ Carbide Drill Bit — the standard compact configuration of Milwaukee's premium four-cutter MX4 bit at the 5/16 in. anchor diameter. The MX4 four-cutter tip uses four active carbide cutting edges simultaneously engaging the concrete surface per revolution, doubling the cutting contacts of conventional two-cutter SDS+ bits for faster penetration rate and proportionally extended bit life from doubled carbide wear distribution. The 5/16 in. diameter serves concrete screw anchor and expansion anchor systems where the slightly larger bore than the common 3/16 in. provides better anchor engagement geometry for specific anchor types while remaining in the light-duty anchor category — applications include specific concrete screw anchors, specialty expansion fasteners, and light structural connections where 5/16 in. is the specified pilot hole size.
The 6 in. compact overall length with 4 in. flute is the standard configuration for most 5/16 in. anchor applications where typical anchor embedment depths fall within the 4 in. working length range, and where the compact 6 in. bit provides the positional advantages of a shorter bit in overhead and confined-space drilling situations. At 5/16 in. diameter in hard commercial concrete, the MX4 four-cutter advantage delivers meaningful drilling speed improvement and bit life extension over standard two-cutter bits — the four cutting contacts maintain penetration momentum through hard aggregate that two-cutter bits slow more noticeably at this small diameter. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes.
