Categories : tools
SKU : WOR-TOO-1083
The DEWALT D25951K packs 29 pounds of SDS Max demolition power into an inline design that keeps your arms behind the bit for better control. It's built to handle concrete breaking, chipping, and chasing on job sites or renovation projects. The SDS Max shank accepts a wide range of chisels and points, giving you the versatility to switch from demolition to detail work.
To keep this hammer performing at its best, regular service matters. The D25951K has accessible maintenance points: the SDS Max shank should be cleaned and greased regularly, and the oil level should be checked per the operator's manual. A little routine attention between big jobs will extend the tool's life and maintain impact energy.
Always unplug the hammer before service. Wipe the SDS Max shank clean, apply a thin coat of approved grease, and work it into the chuck. Check the oil reservoir and top up or change the oil as specified in the manual. If you notice reduced impact or unusual noise, stop and inspect the grease and oil levels first.
This demolition hammer is a solid choice for concrete slabs, block walls, and heavy tile removal. The inline configuration improves balance, reducing fatigue during longer chipping sessions. Pair it with quality SDS Max chisels for the best results, and keep a spare grease cartridge in your toolbox.

Demolition hammers work hard, and the D25951K is no exception. Routine service is the cheapest way to avoid downtime. We cover the basics here, but always follow the operator's manual for exact specs.
Unplug the tool and remove the chisel or point. Wipe off old grease and debris from the shank, then apply a thin layer of recommended grease. Slide the accessory in and out a few times to distribute the grease. Do this before each heavy use session.
The inline design gives you a clear view of the oil window. Top up with the oil type listed in your manual if it's low. An oil change is typically recommended after every 50–75 hours of heavy use, depending on conditions. If the oil looks milky or dark, change it sooner.
If the hammer sounds different or loses power, stop and inspect. Air leaks, worn brushes, or low oil can turn a small problem into a major repair. Keeping a grease and oil kit with the tool makes regular maintenance easy.
Check the operator's manual for the exact interval, but a good rule is to clean and grease the shank before each extended use or when you notice reduced impact.
Use the oil specified in the DEWALT manual. Typically a high-quality air tool oil or gear oil is recommended. Never substitute with general-purpose motor oil unless the manual allows it.
No, this is a demolition hammer designed for chipping and breaking. For drilling holes in concrete or masonry, use a rotary hammer with a drill mode.
The hammer uses an SDS Max shank, so any SDS Max chisel or point with a compatible profile will fit. Keep the shank clean and greased for smooth insertion and removal.
This thing shreds concrete!
Broke up a small slab in under fifteen minutes. Much easier on the back than my old rotary hammer. Vibration is low for a 29 lb tool.
After forty years of commercial concrete work, I've owned every major brand. This DEWALT inline hammer is the most comfortable to handle for long periods. The chipping power is consistent, and it doesn't rip your arms off like some other machines. I used it to remove tile and mortar in a bathroom, and I was amazed at how little debris was left. The inline design keeps your weight centered, so you're not fighting the tool. Only complaint is the price, but you get what you pay for in this business.
I'm a general contractor and this hammer gets the job done. It took down a concrete footer without any issues. The vibration is manageable, but it's heavy for overhead work. I'd recommend renting if you only need it once, but for daily use it's worth buying. The carry case is sturdy too.
Great power. Heavy, but worth it.
I've used a lot of hammers over the years, and this one is a keeper. It handles rebar and concrete without slowing down. Clean power, no jams.
Dude, this demo hammer is insane. I used it to take out a concrete patio in my backyard and it was done in a day. The inline handle means you don't get thrown around like with a regular jackhammer. It also comes with a nice grease gun and I like the carrying case. Battery? I mean it's corded electric, so you just plug it in and go. My neighbor asked to borrow it and I said no way, haha.
It has no problem breaking concrete, but it's really heavy to lift. I got the job done but my back aches. Also, the dust gets everywhere, but that's expected.
I'm a retired contractor, and I bought this for occasional projects. It works exactly as the spec says. The anti-vibration is legit; I used it for an hour and my hands didn't go numb. It made quick work of a brick wall. If you're on the fence, just get it.
I compared this to a Bosch and went with the DEWALT. Cut through a concrete slab with no issues. The only reason I give 4 stars is that the side handle feels a bit flimsy, but it works.
