Product Description
Milwaukee 3/8 in. x 6 in. MX4 SDS+ Carbide Drill Bits — 10 Pack
Model Number: 48-20-7951
The Milwaukee 48-20-7951 is a 10-pack of 3/8 in. diameter x 4 in. flute length x 6 in. overall length MX4 SDS+ Carbide Drill Bits — a value-pack quantity of Milwaukee's premium four-cutter MX4 bits at the 3/8 in. diameter for commercial anchor installation crews who need MX4 performance in a mid-volume pack format between individual bit purchasing and the larger 15-pack and 25-pack quantities. The 10-pack provides enough bits for significant anchor installation work on a project or service scope while keeping initial inventory investment lower than the larger bulk packs — a practical format for contractors who want MX4 performance benefits without committing to the full bulk quantity before confirming the bit's performance advantage in their specific concrete conditions. The MX4 four-cutter tip's four active carbide cutting edges per revolution deliver faster penetration rate and extended bit life compared to standard two-cutter SDS+ bits, with the performance advantage most significant in the hard high-strength commercial concrete where 3/8 in. structural anchors are most commonly installed.
At 3/8 in. diameter, the MX4 is the highest-value MX4 specification for commercial concrete anchor installation — 3/8 in. is among the most drilled anchor sizes in commercial construction, and the accumulation of drilling time saved and bits replaced across the large quantities of 3/8 in. anchors installed on a commercial project makes the MX4 cost premium easily justified by the productivity gain and bit cost reduction it delivers. Milwaukee's manufacturing consistency across all 10 bits in the pack ensures predictable MX4 performance from the first bit to the last. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during production anchor drilling operations.
Individual unit (48-20-7351), 15-pack, and 25-pack formats available for different volume requirements — see Milwaukee's MX4 lineup for all available pack quantities at the 3/8 in. diameter.
