Description
Milwaukee SDS+ Bit 3/8 in. x 4 in. x 6 in.
Model Number: 48-20-7451
The Milwaukee 48-20-7451 is an SDS+ rotary hammer drill bit in 3/8 in. diameter with a 4 in. working length and 6 in. overall length — the standard compact configuration at the most heavily used commercial anchor diameter for the majority of ceiling and wall anchor drilling applications in commercial construction. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized fluting for consistent concrete drilling performance. The compact 6 in. overall length provides the access advantages of a shorter bit for overhead ceiling anchor installations where the drill must be positioned directly below the drilling location — keeping the drill control point as close as possible to the ceiling surface for comfortable, accurate overhead drilling with standard-height arm extension rather than requiring ladder repositioning for adequate control.
The 3/8 in. diameter is the most commonly drilled anchor size in commercial construction — it serves the full range of light-to-medium structural anchor systems across conduit support, equipment mounting, and general structural fastening that define the everyday anchor drilling work of commercial construction projects. The 4 in. working depth handles the typical light-duty and medium-duty anchor embedment depths for most concrete screw, wedge anchor, and drop-in anchor installations in standard commercial concrete at this diameter. For high-volume production anchor installation at this standard configuration, the 25-pack (48-20-7551) provides significantly better per-bit economics than individual unit purchasing.
See Milwaukee’s complete 44 Magnum SDS+ catalog for all available 3/8 in. lengths and pack quantities from individual through 25-pack.
