Question: Do i need to purchase the batteries separately? Isn't it included in this purchase?
Document: That best tool and to make my job faster and I recommend this item to buy it  so u guys need to by one
Best purchase made so far, works and saves alot of time than using standard sockets to do a job. Small and ideal for tight spots.
I can't Brag enough about this impact!!! I use it every day as a Heavy Equipment Mechanic. I keep it on my service truck and use it daily. It has a lot of power and is very compact. The Batteries I use have a charge indicator, which I highly recommend.
We purchased two of these for our shop where they are used several hours per day in a manufacturing environment. Highly adjustable using the hog-ring, the guys in our shop couldn't be happier. Batteries seem to last a long time between charges and the 20 volt power is just what we needed. Our primary uses are stainless steel flat-head, socket-head, and shoulder screws, anywhere from 10-32 through 1&#34;-8. Highly Recommended.
I have a Dewalt impact Driver for screws, but if you're going to try to punch lag bolts or timber screws into treated 2x's for deck building or automotive use, get this 20v impact Wrench. This item was an Amazon Warehouse Deal and it was discounted, it actually was a factory sealed refurbish, clean as New, not a used-bumped and bruised return item.For a $100 shipped for a bare tool (I have plenty 20v Dewalt batteries), I got lucky on this deal.
I was floored. A week or two later I was using it to drop skid plates off of an old 4x4 and I wondered if DeWalt made a 3/8&#34; version. Quick Amazon search and I found this tool, and a few days later I was using it to bust loose hardware that I would have sworn needed an air compressor or a torch. I'm impressed - If you already have the 20Vmax setup and you work on anything bigger than a dirtbike, you need this tool.
Remember, if you're using this to fasten or tighten a nut/bolt, do not hold down too long when the bolt/nut is flush against whatever you're tightening/fastening, this thing is powerful enough to either strip the bolt threads, or drive the bolt through. Of course, you'll realize the do's and don'ts when you play with this thing.PROS:- Very ergonomic, excellent weight balance, comfortable grip- Build quality seems excellent (don't like how it's made in Mexico, but can't do much there)- 3/8 Drive accepts a wide variety of sockets and attachments- Small/Compact to fit in tight spaces- Seems to last long using DeWalt 20V 2.0 Amp Hour Lithium Ion Battery (Will accept all other DeWalt 20V 1.5, 2.0, 3.0, and 4.0 amp hour batteries)- 3 L.E.D.
lights are pretty bright and light up work area nicely- POWERFUL @ 130ft/lbs; pretty much can loosen/fasten any bolt with ease.CONS:- made in mexico- does not use a brushless motor (more efficient, less wear), uses brushed motor (less efficient, a little more wear, slight burning smell). You will smell a slight burning smell when using, but this is normal.- no other cons so far, highly recommend this product.Other Thoughts: Keep in mind that part number DCF883B is the bare-tool only.
i have a lot of 20 volt dewalts and this is another one. this one has the 3/8&#34; square. runs like a champ and takes a beating.
absolutely love this impact, i use it about everyday.! thanks dewalt awesome awesome. I enjoy the 20v max line up.
