Yes, I would recommend this to a friend (8)
I love my rotary hammer drill I just wish I could find a good place to buy bits for.drill works great
July 31, 2019
This thing is a beast! I literally don’t touch the drill/driver model anymore

Another Quality Product from DeWalt
A must have to drill or chip concrete and block. Works just as good as my corded Hilti Te5 drill !!!
July 15, 2017
With out a doubt this tool pays for its self. I build mini storage buildings and there are many occasions where this comes in handy. i may have to run out 300 feet of cord to drill 1 hole that was missed for example. I've never used any other brand cordless rotary hammer drill. And after using this one, I never will. I use dewalt 6 ah battery with it.
June 30, 2017
more powerful than i thought it would be
used this week end and was surprised at the power and speed of the hammer drill. real good value and its battery did real good
May 21, 2017
I'm a master electrician and this item is very useful, powerful, and reliable. I would recommend it to anyone in the trades.

You won't be disappointed.
January 8, 2017
great for tapcons and 3/8 anchors , all day, in the hardest concrete
January 8, 2017
Worth it at twice the price!
Performs flawlessly. Brushless motor is easy on batteries. Have used similar u n it from Hilti but that one came with a $1700 price tag. Very good comprimise for having to haul a generator for smaller demo jobs.
November 24, 2016
Very handy tool! Works especially well for tapcons and the like. Larger holes do wear the battery down faster, but still incredibly useful when a corded tool is not an option. I use it nearly every day on the jobsite and it's the second one I've bought now and will likely buy another one when this one wears out. Two thumbs up for sure!
November 2, 2016
Very happy with the tool if has done everything ive 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.
