Product Description
Milwaukee 3/16 in. x 6 in. MX4 SDS+ Carbide Drill Bit
Model Number: 48-20-7311
The Milwaukee 48-20-7311 is a 3/16 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 3/16 in. light anchor diameter. The MX4 four-cutter tip delivers four active carbide cutting contacts per revolution versus the standard two-cutter of conventional SDS+ bits, providing faster penetration rate and extended bit life by distributing carbide wear across four contact points rather than two. At the small 3/16 in. bore, the four-cutter advantage is most pronounced in hard commercial concrete where the small cutting face encounters maximum aggregate resistance per unit of cutting face area — four cutting contacts maintain momentum through hard aggregate that would stall or slow a two-cutter bit's progress noticeably at this small diameter in dense commercial concrete conditions.
The compact 6 in. overall length with 4 in. flute is the standard configuration for the typical light-duty anchor embedment depths at the 3/16 in. size — covering concrete screw anchor and small expansion anchor installations in standard commercial concrete at ceiling height and wall positions. The compact length provides the access advantages of a shorter bit for overhead ceiling anchor installations and tight-clearance confined-space drilling positions. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers. Available in 25-pack and 100-pack quantities for production-volume purchasing at lower per-bit cost.
