These are the best
This one, with the quick lok cord is the best. You can add 25' of cord to the tool with the twist of your wrist and the not have to drag a knot to an extension cord with you on the 8 or 10' standard length cord. I purchased mine for automotive work and equipment repair and with the 25' long cord on it, it has been more useful then I expected. One thing you can do is add an adapter that takes you from the 1/2" square drive to 7/16 hex quick change, Milwaukee makes one, and I hope they do not drop the part, because it will turn this into a hole drilling machine. The impact is the best platform for running auger bits, especially the long ones, and you can also use the heavy duty Milwaukee extensions for drilling sole plates for piping with these guys. The forward reverse above the trigger is great and there is also a variable speed dial for dialing down the tool that is good to have as well. Great for an heavy duty automotive work, and great for drilling, and you can have 25' of cord from the tool. Total win for the user. Once you have one, you will use it a lot.

Only one con - if you look at this compared to the other quick lok corded version that had the 7/16 insert chuck attached to the tool, where you can insert the bit, or 1/2" square drive to the tool, is this does not have the ring that allows you to easily attach it to a tool belt when in use. KInd of a minor con, but the case has room for one to fit, and I ordered the parts for the ring and added one to mine.

Previous posted said the nub on the square was annoying, bit that will depend on what you do. If you do not want the socket to fall off, you will like nub. It does mean you will need a small punch to disengage it. One work-around is use a small extension to quickly flip between sockets. For me I you use the 1/2" square to 3/8" square step down for equipment repair work a lot, and it keeps that adapter on the tool, so I kinda like it.

Where have you been all my life?
Bought this when preparing for an axle replacement task. This impact wrench made quick work of the lug nuts, strut bolts and big axle nut even without unstaking it. I've removed wheels all my life with the old cross lugnut wrench and this transformed the chore into a no-effort job. Having a corded tool without the need for a compressor or air hose is convenient. It is a fairly heavy tool which is expected for something with this much torque, but if I wanted something lighter, I'd get a weaker tool or use hand power.

Now for the little nits: The direction switch does get knocked back and forth inadvertently so just check each time before you pull the trigger. It does not have a clutch to stop the wrench when you release the trigger so it will keep spinning. Don't use this to tighten automotive bolts or lugnuts unless you don't mind really cranking them in there.

All in all, this is a great tool and CPO was a great vendor. The tool was shipped in its original box and doubled up with an outer box which was well packed and delivered promptly.

Easy to use heavy duty item
I tried to use a plumbers wrench to loosen rusted clean out plug on sewer drain. Hurt my back and still could not get it to budge. Ordered the electric plug in 1/2" impact wrench and quickly was able to get it removed with no pain or problem. Product is heavy but I expect that in a strong heavy duty item. Great power for an electric. Much more convenient for occasional use than buying air impact tool and compressor.

Did what I needed it for.
I was in the middle of changing my brakes and rotors. I got stuck on this 15mm bolt which I couldn't get undone not even with a 2 ton jack pushing up against a breaker bar. Of course I stopped before I broke the breaker bar or bolt. With out compressor I knew I was gonna need an electric impact. I'm not experienced with impact wrench's other than the few times I used the air ones with my dad when I was young. This is my first and only one and it did exactly what I needed it to do.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
