Milwaukee SHOCKWAVE Deep Well Impact Socket, 1/2 in. Drive

Milwaukee 49-66-4466 SHOCKWAVE 1/2 in. Drive Deep Well Impact Socket, 11/16 in.

The Milwaukee 49-66-4466 is a SHOCKWAVE 1/2 in. drive deep well socket sized to 11/16 in., designed for use with impact wrenches, impact drivers, and standard 1/2 in. drive ratchets. As part of Milwaukee's SHOCKWAVE accessory lineup, this socket is engineered to hold up under the repeated torque, vibration, and impact loads generated by power tools on the jobsite. The deep well profile extends the working depth of the socket beyond that of a standard socket, allowing it to fully seat over long bolts, studs, and fasteners that protrude or sit recessed within an assembly. This 11/16 in. deep well socket is sold individually, making it a straightforward way to fill a gap in an existing 1/2 in. drive socket set or replace a worn or lost socket without purchasing an entire new set.

Key Features

• Drive Size: 1/2 in. square drive is compatible with standard 1/2 in. drive impact wrenches, impact drivers, and ratchets.
• Socket Size: 11/16 in. opening is sized to match common fastener head dimensions found in automotive and mechanical assemblies.
• Deep Well Design: The extended depth of this socket reaches over long bolts, studs, and fasteners that sit below the surface of an assembly, where a standard-depth socket would not make full contact.
• SHOCKWAVE Accessory Line: Manufactured as part of Milwaukee's SHOCKWAVE lineup of impact-duty accessories, built to handle the demands of repeated impact-driven fastening.
• Individual Socket: Sold as a single 11/16 in. deep well socket, allowing technicians to replace or expand a 1/2 in. drive socket set one size at a time.
• Impact-Ready Use: Designed to be paired with impact wrenches and impact drivers for faster fastening and removal compared to hand tools alone.
