The Milwaukee 49-66-6800 SHOCKWAVE Impact Duty Socket 3/8" Drive 17-Piece SAE PACKOUT Set is a 3/8-inch drive SAE impact socket set built for high torque fastening and service work. This is a socket set designed for impact wrench, impact driver, ratchet, and adapter use in automotive, mechanical, and general shop applications. Model Number: 49-66-6800. If you need deep SAE sockets that are easy to identify, hold up under impact use, and stay organized between jobs, this set is aimed right at that problem.

Milwaukee built this set around the stuff that matters in real use. The sockets use forged chrome molybdenum steel and a 6-point opening, which is the right move for impact duty because it helps handle repeated torque loads while putting better contact on the flats of the fastener. The non-slip hex geometry is there for the same reason. It helps reduce socket and fastener rounding, which is a big deal when you are working on stubborn hardware and do not want a quick repair turning into an extraction job.

One of the better details here is the marking system. Milwaukee uses stamped and ink-filled size markings, so the sizes stay readable longer than basic printed markings. That saves time every time you reach into the tray for the next socket, especially if the set lives in a truck, service cart, or busy garage. This is the kind of feature that sounds small on paper but makes daily use a lot less annoying.

The attachment design is also job-focused. Milwaukee uses a dual-hole design and groove for easier socket attachment and removal. If you regularly swap sockets on impact tools, ratchets, and adapters, that detail helps the set feel quicker and less fussy. The kit is optimized for use with 3/8-inch drive impact wrenches, drivers, ratchets, and adapters, so it covers a wide range of fastening setups without asking you to piece together a mixed bag of sockets from different sets.

Storage is a real selling point on this set. Milwaukee includes a PACKOUT Compact Low-Profile Organizer with a clear top, plus a removable tray. That gives you two ways to work: keep everything protected and stackable in the PACKOUT system for transport, or pull the tray out and drop it into a tool chest when you are working in one spot. If you already use PACKOUT, this fits the system cleanly. If you do not, it is still a solid organizer that keeps the set from turning into a loose pile of sockets.

In terms of coverage, the kit includes 14 deep SAE sockets plus 3 accessories. The socket sizes run from 1/4 inch to 15/16 inch, and Milwaukee also includes a 1/4-inch hex to 3/8-inch square socket adapter, a 3-inch extension, and a 3/8-inch universal joint. That makes this set more useful than a basic socket-only tray because you can reach a little farther, work around slight offsets, and use the sockets across more tool setups right out of the box.

For buyers deciding between a cheap socket rail and a real impact socket kit, this Milwaukee 3/8 drive socket set earns its keep with durability, readability, and storage. It meets ASME industry standards, and Milwaukee backs the impact sockets and extensions with a Lifetime Guarantee. The honest take: this is a strong choice for mechanics, equipment techs, and serious DIY users who want a clean SAE deep socket set in a PACKOUT-ready format. If you work mostly in metric, this is not your set. If you need SAE impact sockets that stay organized and survive regular abuse, it makes a lot of sense.
