Product Description
Milwaukee SDS+ Bit 3/8 in. x 10 in. x 12 in.
Model Number: 48-20-7454
The Milwaukee 48-20-7454 is an SDS+ rotary hammer drill bit in 3/8 in. diameter with a 10 in. working length and 12 in. overall length — the extended-length 44 Magnum configuration for the 3/8 in. diameter enabling through-wall CMU penetrations, deep embedment structural anchor installations, and other drilling applications requiring more working depth than the standard 6 in. and 8 in. configurations provide. The 3/8 in. diameter is among the most commonly used anchor sizes in commercial concrete construction, and the 12 in. overall length extends the application range to include through-wall penetrations in standard 8 in. and 10 in. CMU block construction, anchor installations where engineering specifications require deeper embedment for higher pull-out load ratings, and drilling positions where obstacles between the hammer and the wall surface require additional bit length to reach the drilling location from the available clearance position.
Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized helical flute geometry that maintains efficient concrete debris evacuation throughout the full 10 in. working depth — preventing the hole choking and bit binding that undermines drilling speed and productivity in extended-length bits with inadequate flute design. The 12 in. length at 3/8 in. diameter represents a combination heavily used in commercial anchor installation for structural connections and conduit support systems on projects where the concrete section thickness or anchor embedment depth specification requires the extended length. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during production drilling operations.
Available in 25-pack bulk quantities for high-volume commercial anchor installation — see Milwaukee's complete 44 Magnum SDS+ catalog for all available lengths, diameters, and pack quantities.
