DEWALT 20-Volt MAX XR Cordless Brushless 7/16 in. High Torque Impact Wrench Quick Release Chuck & (2) 20-Volt 5.0Ah Batteries

This review is for the 20-Volt MAX XR Lithium-Ion Cordless Brushless High Torque 7/16 in. Impact Wrench with Quick Release Chuck (5.0Ah)This is a serious tool. The Impact Wrench itself weighs in at just over seven pounds. The batteries that come with this set are the largest 20V that Dewalt makes, with a rating of 5.0 mAh.I went to my usual testing for such a high powered tool. Taking off lug nuts on an old truck. Yes they are gross and rusty.This Dewalt tool barked and hummed and bam off the lug nuts came. This tool appears to be built for the long haul.Comes with two of the big 5.0 batteries and charger. Dewalt soft handled zipper case included.

Nice impact so far plenty of torque.

From what little I have used it, it has met my expectations

This is a powerful impact wrench that is used primarily for drilling large holes with augers that have a 7/16″ hex shank. It comes with a 7/16″ quick release chuck. My husband uses this tool to drill 1″ holes through 2×4 studs to run electrical wire. He has tried regular drills and a hammer drill but these can bind easily and give your wrists abrupt twist. With this tool, he can drill these 1″ holes using one hand and avoid the binding. The drill/impact wrench has a fastening torque of 700 ft. lbs. and breakaway torque of 1200 ft. lbs. It also has an LED and speed control that adds to the ease of use for a variety of applications.A much better solution for us. We are exploring how it might also be used for smaller drill bits, screw driving and sockets. So far, we are finding that adapters for doing this are not common/plentiful and the adapters are not rated for use in impact applications. We believe and hope that in the near future this will change and we can use this impact tool for everything — putting in screws, tightening bolts/nuts, and using drill bits of all types. When this happens, we think we will prefer this tool over any other drill type.

Worked great! Used the impact all day heavy use for a whole week before I had to charge the first battery! Love the power and performance it puts out!

Features: 3 speed/torque settingsThis impact driver comes with 3 settings. You’ll need to use them appropriately because this tool has the ability to break practically everything if you aren’t careful. The user will not feel any kickback or binding regardless of the selected setting. The one thing you lose when using a tool this powerful is that you can’t feel how much force is actually being delivered to the bit.Integrated LightThis tool has the best integrated light I’ve used. It’s bright enough that I don’t need to reach for a shop light or turn on my headlamp when I get caught out after dusk. Again, this is a safety boon as much as a convenience issue because this tool is very powerful and drives bits very quickly and you need to be able to see what you’re doing at all times.QR ChuckI’ve only had the tool for three weeks so I can’t comment on the durability of the chuck. I’ve already noticed on my large drill bits that the chuck is definitely harder than the metal the bits are made from, which is good because replacing bits is much easier than replacing a chuck. Also, the fit between my bits and the chuck are very secure and they lock into the driver with a solid action.Overall User Impression: 2-by, 4-by, 6-by, bye-bye. This is the tool to buy when you wish you could buy more time. This is the tool to get when you never want to be 25′ up a ladder wishing for more power. You can drive a 1.25″ diameter 18″ long auger bit into wet logs with just one hand, then turn around and chuck in an adapter and take off the lug nuts on your truck. This tool is heavy, but it makes up for it by blasting through jobs faster all while putting less force on the user.Recommended For….Those that build pergolas, cabins, tree houses, etc on a regular basis due to the 7/16″ QR chuck that will securely interface with all the heavy duty wood bits you currently use.Not recommended for……Prolonged mechanical work. There are adapters that goes from 7/16″ to 1/2 square drive, but none are impact rated and all would absorb a lot of the initial impact torque that makes a tool like this so useful.

This special purpose 7/16 inch quick release hex shank chuck impact wrench is one beast of a tool that tackles any fastening and wood boring task you put in front of it no matter how tough the job. The brushless high torque impact wrench is made exceptionally well and boasts the quality and performance you expect from Dewalt. The 20 volt MAX XR impact wrench has an efficient motor design, three speed switch to match application and includes two high capacity 5 Ah batteries for the longest run time. The 7/16 in. hex chuck makes it ideal for use by electricians or anyone else for boring large holes thru pressure treated 4″ X4’s, 6 X 6’s , etc. Any 7/16 inch shanked auger bit or hole saw will work with this impact wrench and a 7/16″ hex shank to 1/2 inch square socket adapter also allows it to be used with any impact rated 1/2 inch drive socket to fasten or remove lag bolts and nuts. The large bull ring allows the lifting and/or securing of tool especially when used up high by linemen on telephone poles for the installation and maintenance of power lines and more. This cordless tool is a great replacement for corded 7/16 inch impact wrenches. I have used this impact wrench to bore a 1 1/4″ hole thru several 4 X 4 pressure treated posts for an upcoming project and I purchased an adapter to use with 1/2 inch drive sockets to loosen lug nuts, etc.
