Product Description
Milwaukee SHOCKWAVE Insert 3/8 in. Socket Adapter — 10 Pack
Model Number: 48-32-5721
The Milwaukee 48-32-5721 is a 10-pack of SHOCKWAVE 3/8 in. Socket Adapters — insert-length adapters that connect 3/8 in. drive sockets to the 1/4 in. hex shank of cordless impact drivers, enabling impact driver use for socket fastener driving without a separate impact wrench. The 3/8 in. socket adapter bridges the gap between the 1/4 in. hex impact driver chuck and the 3/8 in. square drive that fits the large inventory of standard 3/8 in. drive sockets most mechanics, electricians, and contractors already own — converting any Milwaukee cordless impact driver into a socket driving tool for nuts, bolts, and hex-head fasteners in the 3/8 in. drive size range. This expands the impact driver's utility significantly without purchasing a separate impact wrench, allowing a single tool to handle both driving and socket fastening tasks across the workday.
Milwaukee manufactures these adapters to the SHOCKWAVE standard — the same proprietary steel and heat treatment process used across the SHOCKWAVE bit lineup for impact driver compatibility. The Shockzone geometry in the adapter shank absorbs peak torsional impact energy from each impact driver hammer strike before it reaches the socket drive interface, protecting both the adapter and the socket from the progressive damage that occurs when standard drill chuck adapters are used in impact drivers without impact-rated construction. The 10-pack format provides practical multi-unit purchasing for shop use, fleet tool kits, and crews where multiple impact drivers need socket adapters simultaneously, at reduced per-unit cost compared to individual purchasing. At 1 in. insert length, these adapters position the socket close to the driver chuck for compact, controlled socket fastening.
