Soviet equivilent to milwaukee if it were an analogy drill.
Gets done. You tired? It ain't. These things run forever off one battery, (pad your shoulder before drilling for anchors, take the name-calling) and is right there with the chop-saws on jobsite "what gets used". These are solid machines and any contractor can tell you so. They just....keep drilling. Burning your hand? Keep drilling. To heavy? Keep drilling. Throwing sparks? DRILL HARDER. The Dewalt will always make it, the man usually falters.

Awesome Tool
Another great addition to the toolbox. Good power on all stages of drilling hammer& drilling and straight hammer for chipping. Fits all SDS bits up to 1 inch.

Seems as good as my old Corded Bosch Bulldog
My old corded Bosch Bulldog hammer drill finally died. I was a little skeptical about getting a battery powered hammer drill, but after using it a few times I'm pleased with it's performance. I already have several Dewalt 20V tools so I didn't need the battery. If you are hammering a 1/2 or larger hole through a concrete foundation, you may go through a few batteries, but the power seems to be as good as that from my old Bosch.

Great dewalt hammer drill
Lots of power. Easy to use. Drills 3/4” holes into very hard concrete and rock with ease in seconds. Use water to keep bits cool and longer lived.

Good product. Would buy again.
Used this to drill holes in to a granite mailbox post. It worked fast without any issue. Good product! Would buy again.

Estás súper solo q en las imágenes del vendedor sale como si alumbrara y realmente no tiene ninguna luz, si vas a trabajar en un lugar con poca iluminación recuerda llevar una linterna a parte de esto todo lo demás genial gran potencia.

Unbeatable rotary hammer!
It's a Dewalt power tool. That sums everything up pretty much. I admit I haven't used it much at all minus as a regular drill since I got my SDS+ to 1/2" chuck adaptor. Will be removing a LOT of tile at home in the near future. The hammer isnt overly heavy, and definitely has the power necessary to destroy concrete when paired with a good chisel. You'll definitely want at least a 5AH battery for this bad boy. I went with 2 6AH to be safe. Whether you're hammer drilling, regular drilling [w/adapter chuck], or just plain hammering/chipping, this tool will get the job done. Only real complaint I have is they didnt put a light on this tool. My hammer drill has a light with 3 brightness settings. Even a non adjustable light would've made this thing perfect. If you're on the fence over this model or the compact, go for this one! It has more impact joules energy and costs waaaaaay less. If you're working in tight spaces though, then you'd definitely want the compact model.....obviously. Since I haven't had this tool very long, I'll update if any issues arise, but I don't foresee that happening. Fourth Dewalt brushless cordless tool and no issues with the first 3.....even after one fell into a pool for a couple of minutes. Dried out the impact driver and it's still kicking ass a couple of years later! You can't go wrong with Dewalt. Period.

What a great SDS Hammer Drill to add to the fleet!
I have been a firm believer in Dewalt battery tools since the 18 volt oval battery days. After selling my 18 volt converted to a 20 volt SDS Drill a while back, I came across the need to own another, as a project to add 30 plus shelf standards attached to concrete basement walls came up. After looking at the Bosch corded - which i found hard to beat from past use, I instead went with a cordless SDS, the bare tool Dewalt SDS I am reviewing. This thing is light, and first thoughts was that it wouldn't keep up with what I was needing to do. But once I started drilling any concern was resolved, this thing was a beast. Coupled with the 60 volt Flexvolt, it drilled flawlessly for over an hour, a total of 115 holes drilled. This were 3/16" and posed no problem for the drill or the Bosch bits. I haven't tried a 1/2" or 3/4" hole, that day is yet to come, but form what I needed, this drill knocked it out of the park.

Super powerful hammer drill. Love that it is cordless. Was worried it would not have the same power as a corded hammer drill, but no worries with this one. Drilled into brick with ease. Great product.

Sin duda lo volvería a comprar

I wear yellow underwear so I'm biased but this is a great hammer drill. Perfect for lags or tap cons. Lots of power and it is light so one handed operation is possible. Very impressed. Better that my plug in from another manufacturer.
