Product Description
Milwaukee 3/16 in. x 4 in. MX4 SDS+ Carbide Drill Bit
Model Number: 48-20-7310
The Milwaukee 48-20-7310 is a 3/16 in. diameter x 2 in. flute length x 4 in. overall length MX4 SDS+ Carbide Drill Bit — the ultra-compact individual unit of Milwaukee's premium four-cutter MX4 bit at the 3/16 in. anchor diameter, providing the MX4 four-cutter performance advantage in the shortest standard configuration for overhead and confined-space anchor installations where bit length directly affects drill positioning capability. The MX4 four-cutter tip delivers four active carbide cutting contacts per revolution — doubled versus the standard two-cutter conventional SDS+ design — for faster penetration and extended bit life in hard commercial concrete. The 4 in. overall length with 2 in. working depth is the most compact SDS+ bit configuration available, specifically designed for the tightest-clearance drilling applications where even the standard 6 in. bit creates positioning challenges.
The ultra-compact 4 in. length is most valuable in overhead ceiling anchor drilling where keeping the bit-to-ceiling distance as close as possible allows the drill to be positioned with less awkward arm extension overhead, in near-corner drilling where the wall and ceiling intersection severely limits available bit clearance, and in mechanical rooms and tight spaces where structural elements and equipment crowd the drilling access space. At this compact length, the 2 in. working depth serves the typical 1.5-2 in. embedment depths of light-duty concrete anchors in standard commercial ceiling installations — the depth matches the application requirement so there is no excess bit length extending beyond the hole that would create clearance problems in the most confined drilling positions. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers.
For applications requiring greater working depth, see the standard 6 in. configuration (48-20-7310 series) and extended lengths — the MX4 four-cutter advantage is available across the full range of lengths at the 3/16 in. diameter.
