Description
Milwaukee 7/16 in. x 6 in. MX4 SDS+ Carbide Drill Bit
Model Number: 48-20-7361
The Milwaukee 48-20-7361 is a 7/16 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 7/16 in. diameter for medium structural anchor pilot hole drilling. The MX4 four-cutter tip delivers four active carbide cutting contacts per revolution versus the two-cutter standard of conventional SDS+ bits, providing faster penetration rate and extended bit life by distributing cumulative carbide wear across twice the surface area. The 7/16 in. diameter serves specific medium-duty structural connections where this precise bore is specified by engineering requirements, including specific anchor systems and through-bolt sizes where adjacent 3/8 in. and 1/2 in. standard sizes would provide either insufficient or excessive bore for the specified connector hardware.
The 6 in. overall length with 4 in. flute is the compact standard configuration for most anchor applications at this diameter — providing adequate depth for typical structural anchor embedments at the 7/16 in. size while maintaining the compact length advantages of a shorter bit for overhead ceiling installations, horizontal drilling near obstructions, and confined-space drilling positions. Milwaukee’s MX4 four-cutter advantage is most significant in hard commercial concrete where the doubled cutting contact frequency maintains momentum through hard aggregate encounters that slow standard two-cutter bits more noticeably. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during production anchor installation.
See Milwaukee’s complete MX4 SDS+ lineup for all available 7/16 in. configurations and for extended lengths where the 12 in. overall (48-20-7364) is needed for deeper applications.
