Great Tool!
I was going to rent a power hole digger (jack hammer yesterday because it took me over an hour to get one hole bug using a hand post hole hole digger, chisels, and digging by hand. I had 10 holes total to do! In Texas we have cliche and rock. I purchased this tool and was able to dig a hole in 3 min, I love Dewalt tools! It is all I purchase!

The hammer drill is lightweight and easy to use, even with one hand. Bits are can be changed with ease. The belt clip is a life saver especially when working off ladders. Would recommend this tool to anyone looking for a hammer drill

Great Rotary Drill
This product works great for boring brick, mortar, and even stone. Paired with the proper bit, this hammer has assisted plenty of projects so far. Equipped with chisels, this hammer easily breaks apart mortar joints great for demolition. With this, it is durable, portable, and decently lightweight.

I am in HVAC and mechanical and I use this for anchors for hanging strap and setting units. It is light weight so it is easy to use above head and it fits great inside condescending units without hitting the compressor or coil. The clip is a very nice addition for working on ladders. It also has quite a bit of power. It lasts a long time with a flexvolt battery. I am very happy with this product. Would definitely recommend!

The Yellow BEAST!
This thing is a BEAST! I didn't want to fork over the big bucks for 2-3 days of a demolition hammer rental, so bought this instead. I used it HARD for two days knocking down 10" cement deck footings. Definitely asked more from this SDS+ than it was designed for, but it kept on chugging and got the job done. I would have paid the same money to rent a demo hammer for a couple days as I did to buy this!

It did leak a bit of oil out the chuck for a bit at first when it got hot, but that is to be expected when expansion occurs under force of heat. I have other brushless 20v Max tools, so know how good they are at efficiently using battery power. That said, with such a beefy tool, and asking so much of it, I was really surprised at how long the 5ah batteries lasted.

Another great Dewalt tool!

Super strong!!
This tool is amazing!! It's just as strong as my $400 Bosch corded hammer drill but it's smaller and utilizes lithium batteries. I use it to drill holes for anchoring gate operators and plated posts. I don't k i.e. if ill ever use my Bosch again haha. Best purchase this year!!

Love it.
I use this tool nearly every day, has just as much power as my corded dewalt hammer drill but without the pain of needing a ply in near by.

I should have bought one earlier.
