The Milwaukee 49-66-6805 SHOCKWAVE Impact Duty Socket 3/8"-Drive 36-Piece PACKOUT Set is a 3/8 inch drive deep impact socket set built for high-torque fastening and loosening work. This is a socket set designed for impact wrench, ratchet, and adapter use in automotive, service, and general mechanical applications. Model Number: 49-66-6805. If you need one case that covers both SAE and metric deep sockets without jumping between trays, this set is aimed right at that job.

Milwaukee built this set around real shop use, not just bench-top storage. You get 36 total pieces with deep SAE and metric sockets plus three impact accessories, giving you broad coverage for common fastener sizes. The 3/8 inch drive format is a practical sweet spot for vehicle work, equipment service, and assembly tasks where you want better access than a 1/2 inch setup but more strength than a 1/4 inch setup.

Where this set earns its keep is durability and fast identification. The sockets use forged chrome molybdenum steel for impact duty, and Milwaukee calls out stamped and ink-filled size markings for long-term visibility. That matters more than it sounds. When sockets live in a drawer, a truck box, or a busy service cart, worn-off markings slow you down. Clear size markings save time every day, especially when you are bouncing between metric and SAE hardware.

The socket geometry is also set up for hard use. A 6-point design gives better engagement on fasteners than a looser multi-point fit in high-torque applications, and the non-slip hex geometry is there to help reduce rounding on the socket and the fastener. That is the kind of feature you appreciate after the tool has seen some abuse and you are dealing with older hardware that does not give you a second chance.

Milwaukee also adds practical attachment details with a dual-hole design and ring groove for easier install and removal on impact tools and adapters. For anybody switching sockets repeatedly during teardown or reassembly, that small design choice helps keep the workflow moving. It is one of those shop details that does not show up on a torque chart but absolutely matters on the job.

Storage is a big part of the value here. The set comes in a PACKOUT low-profile organizer with removable trays, so the sockets stay separated and easy to inventory. The organizer has a clear top for at-a-glance identification and is part of the Milwaukee PACKOUT modular storage system. That means this is not just a socket set in a case. It is a socket set that can plug into the same storage stack many pros already use for service kits, hand tools, and consumables.

This Milwaukee 49-66-6805 SHOCKWAVE Impact Duty Socket 3/8"-Drive 36-Piece PACKOUT Set makes the most sense for mechanics, maintenance techs, fabrication shops, equipment service crews, and serious DIY users who want impact-rated sockets with organized transport. If you work out of a PACKOUT stack or want one organized 3/8 inch drive impact set that covers deep SAE and metric sizes in a durable case, this is a smart buy.
