Product Description
Milwaukee 1/2 in. x 6 in. MX4 SDS+ Carbide Drill Bits — 10 Pack
Model Number: 48-20-7971
The Milwaukee 48-20-7971 is a 10-pack of 1/2 in. diameter x 4 in. flute length x 6 in. overall length MX4 SDS+ Carbide Drill Bits — a mid-volume pack of Milwaukee's premium four-cutter MX4 bits at the most heavily used commercial anchor diameter. The 1/2 in. diameter covers the anchor pilot holes for the most common structural anchor sizes in commercial construction, and the MX4 four-cutter tip technology delivers four carbide cutting contacts per revolution versus the standard two-cutter geometry of conventional SDS+ bits, providing faster penetration rate and extended bit life from doubled carbide wear distribution. The 10-pack provides production drilling supply for commercial anchor installation crews who want MX4 performance without the larger upfront quantity commitment of the 15-pack or 25-pack, or for contractors evaluating the MX4 performance advantage before committing to larger bulk quantities.
At 1/2 in. diameter, the MX4 delivers its most commercially significant performance value — this is one of the highest-volume anchor diameters on commercial projects, and the accumulated drilling time saved and reduced bit replacement frequency across the large quantities of 1/2 in. anchors installed in a typical commercial project scope makes the MX4's performance premium easily recovered in reduced drilling time and bit cost. Milwaukee's manufacturing consistency across all 10 bits ensures predictable MX4 performance from first bit to last. The 6 in. overall length with 4 in. flute is the standard compact configuration for most commercial anchor embedment depths and ceiling penetrations at this diameter. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during production anchor installation operations.
Individual unit (48-20-7371), 15-pack, and 25-pack formats available — see Milwaukee's complete MX4 SDS+ lineup for all pack quantities at the 1/2 in. diameter.
