SUMMARY: A NICE MEDIUM-SIZED 3/8” IMPACT SOCKET SET BACKGROUND: I didn’t have a deep well impact socket set, and the Milwaukee 49-66-7021 looked like it would do the job. FIT AND FINISH: One of my first socket sets from Milwaukee. Very heavy duty, with a nice solid feel. FEATURES: From the Home Depot page, with my comments as appropriate. • Kit includes 7 Deep Metric Sockets and 1 Socket Adapter. The following sizes are included: 10, 13, 14, 15, 17, 19, 21, 3/8" Socket Adapter. o Missing the 11, 12, 16, 18, and 20mm sockets. I have them in other sets. Not sure how often I use those sizes. • Boldest, longest-lasting markings and extreme impact durability in high torque applications. The stamped and ink-filled size marking enables users to select the right socket every time throughout the life of the socket. o Very visible, but only marked on one side. • Laser etched part number. o Handy if you need to know. • Engineered with high strength forged steel for optimized performance in heavy-duty applications. o I didn’t see the alloy number, but they feel tough. • Lifetime Guarantee covers impact sockets and extensions only • Optimized for use with 3/8" drive impact wrenches, drivers, ratchets, and adapters o Lol, not sure what this means…but ok. • Non-slip hex geometry prevents socket and fastener rounding. o The radius relieved corners seem to be a common construction configuration now. • Dual-hole design and ring groove allow for easy socket attachment and removal. o The dual-hole design is slightly harder to remove than the internal recesses in some of my other sockets. But I’d rather have them a little harder to remove than too easy. • Customizable Socket Rail comes with interchangeable clips and removeable end caps to add or take off socket clips for optimal storage. o You can do it, but there isn’t room to add any sockets to the rail. • Lifetime Guarantee covers impact sockets and extensions only. • Meets ASME industry standards. o So many standards OPERATION: The sockets slip on and off my ratchets with minimal effort. I ran a long lag screw into a 4x4 test piece with no problems. SUMMARY: A good deal for the money and a welcome addition to my socket collection.

The sockets are great, for me they take the guessing out of which impact socket do I have in my hand. My other impact sockets performed well, but it took a few seconds to properly identify them, the numbers are clearly visible so I was able to grab the correct one each time. This kit lost a star from me for 2 reasons: 12mm sockets are the ones that I use commonly, and they are absent from the kit 2) Even though the sockets are have the oun detent, I was able to remove them with just a tug as they did not sit securely After all this a good kit. I was able to use the 13mm sockets to remove the nuts from the casters that I placed on a homemade cart years ago without any issues.

I was needing a deep socket set that is designed for impact duty for use with my cordless driver. Often times I am using fasteners that too long to work well with my stand sockets. I selected this Milwaukee set primarily because of the bold markings on the socket wall. The deep engraving and the bright white mark makes it very easy to identify the socket size. I'm not certain how well that will hold-up in dirty grease applications but I don't know of any socket that would. Each socket is heavy constructed materials and feels like it will hold up regardless of the driver or torque application. I also appreciate the included SHOCKWAVE 3/8" socket adapter. I also like the included storage rail but it's a real struggle to get the sockets to release from the base. At least I shouldn't loose any of the sockets.

Awesome! These burly sockets look incredible, feel great in the hand, grip well and are up to any task I have for them. I like 6-pt sockets since they grip so well and don’t risk rounding off fastener edges. This set has a grippy matte black finish that feels good in my hand and helps with grip. The star of the show, visually, is the ink-filled size markings and red line on the bottom, and rightly so--it takes no peering over the top of my glasses to see which socket I’m grabbing. I like the organizer rail to keep things tidy. The ⅜” hex socket adaptor included isn’t the weak link so far, and it has a handy keeper on the rail organizer, too. Strong, grippy, deep, easy to read, and covered by a lifetime warranty. This the socket set I’d expect from Milwaukee...so good!

These are really premium deep well sockets. The set comes with all the sizes, from 10mm to 21mm. There is a nice adjustable retaining rack. All sockets are well marked with the size. What I really love about this set is that it comes with an attachment for using these sockets with a drill or battery powered driver! All in all, an excellent addition to any persons tool kit!

The inclusion of the socket adapter means I can use these sockets with the powerful M12 Fuel Surge 1/4 inch impact driver - see video. The M12 ratchet and M18 1/2 inch impact gun got to have a go too. The excellent non-slip hex geometry means the sockets can still drive bolts with worn and damaged corners. The most obvious feature of these sockets is the large, clear etched and inked size markings. A great advantage to users in many circumstances. The rail is good quality and helps to ensure inventory control as it is so obvious when a socket is not on the rail.

If there’s anything a serious DIY needs around the garage and work shop, it’s a heavy duty, dependable set of sockets to fit the standard ⅜” drive tools. Therefore, I picked up a set of the Milwaukee 6-point SHOCKWAVE deep sockets to get my work done, when the metric application is required. Whether working on my lawn mower, appliances, or my pickup truck, the 8-piece set is the way to go. With the 6-point impact sockets, there is no chance of slipping or stripping out a nut that is difficult to grab. The 6-point holds securely, every time. My two favorite tools when using this set are the Milwaukee M-18 impact wrench and the M-12 ratchet. And all the sockets have excellent size marking, clearly visible in low light, when needing to change sizes. The impact wrench is great for general work, and the impact ratchet can get into tighter places. And the most common metric sizes, from 10mm to 21mm, with the ⅜” driver attachment, if necessary. And the best part? Each set comes with its own ‘strip’ to keep them attached and together, so nothing gets lost! This set will tackle pretty much everything around my shop, and should last me a lifetime.

I’ve had multiple impact socket sets for a couple decades. Although I got by with them, they were kind of a pain I just put up with. Key features of this set include: 1. An undercut at the base to improve your grip to pull them off the tool. In addition to the undercut on the body, the red painted groove also aides with this. I’ve had cases with my old sets where I had to use a screwdriver to pry them off the tool. 2. The red painted groove also helps in finding the socket when the job is done. 3. The actual finish also aides in maintaining a grip. It has a satin finish verses the slippery super smooth finish of my other sets. 4. The socket size lettering is recessed into the housing, and then painted white. Should be extremely robust. I was surprised how precise the lettering is. 6. They use a cross-drilled hole for the detent retention. If you have a stubborn ball in the detent, you can use a punch to depress the ball for easy removal. 6. The overall appearance is impressive. I enjoy having tools that look sharp. I store my standard sockets on hanging brackets like this on, but those brackets are not near as robust as this one. This bracket actually has ball detents on the holders. I currently keep all my impact sockets in the drawer with the impact tools.

Needed these after buying a new Kia Soul, needed the 17mm for the lug nuts and choose these Milwaukee shockwave 3/8 metric deep impact 8 piece set. Already owned the Standard set and they are awesome, the stamped/ laser and inked filled numbers make it so easy to get the right size without searching threw tool chest. The 6 point hex opening will give you ease from rounding out nuts, they are solidly made and will take a beating. The 8 piece is 7 sockets and 1 impact sockets adapter so when I want to use with my Ryobi impact driver I just connect socket adapter and off I go, and the tray and clips comes in so handy, no more searching they are all together in one are and with the holes on each end you can mount on your work station very easily. even tho most of my tools are another brand I use only Milwaukee, and these Shockwave sockets are awesome. I have no problems recommending these Milwaukee Shockwave deep impact 3/8 metric 8 piece set to anyone, wether homeowners or professional use. And the bonus is a lifetime warranty.

I received the Milwaukee 8 piece 3/8 inch drive metric impact socket set in good condition. The set includes a plastic organizing strip. The strip can be hung on a pair of nails or screws. The clips can be interchanged by removing the end caps. The sockets are held securely in the clips and will not fall out. As they are used this might change. These are 6 point sockets with off corner loading design. The set includes a 1/4 in to 3/8 in adapter, the only piece made in Taiwan. The sockets appear to be well made in China with a lifetime guarantee on the sockets only. They are black oxide finished and have deep stamping filled with white paint for excellent visibility of the size. I can’t speak to long term durability since I only just got them. I like these sockets and expect good service over a lifetime.
