What "clay digger" tool fits into this hammer drill ?Worked with similar tooling. Good for home use concrete and brick demolition. Can survive fall from second floor.This machine is awesome. My husband was able to remove parts of old driveway (sides) and is now working on a new one. He started landscaping business and this Jack Hammer helps a lot when demolishing is needed. He said he wished the cable was longer but that’s nothing the good extension cord can’t fix. It comes with a sturdy rolling case so it’s easy to move around once unloaded from the truck. It’s HEAVY, powerful and feels indestructible.I'm surprised my fingers were quick enough to grab this baby from Vine. While I don't have a particular reason to own one of these, I recalled borrowing an 80lb jack a few years ago to break up some stone in my yard... that sucked! I also remember how many weekends I needed to break up all that stone... so many! And then I thought, what would it have cost me if I had to rent the jackhammer instead of borrowing a friends? Tool rental prices are absurd!So I do plan to move my shed next year and I'll need to break up the old concrete pylons it is currently sitting on. I'm hoping this hammer will make quick work of the concrete! I'm not so sure it will work well on breaking up granite rocks of medium/large sizes. The item arrived well packaged and in it's case. The case hold the hammer and all associated parts nicely. The wheels on the case make it easier to move this baby around, but as the hammer isn't very tall, you will need to bend your back to roll the case along the ground. Adding a retractable handle akin to suitcases would have alleviated the back bending issue.My unit appeared brand new and the shaft was well oiled and wrapped in a plastic sheath. I kept the sheath on it to avoid oil from running in the case. I am storing it upright in my shed until next spring/summer when I might actually get a chance to really demo some rock! Until then, I'll give this a 4 star review as the item is in great condition and appears to be well built. I will revisit this review next year if the item doesn't function correctly or behaves poorly.This review is for the 1-1/8 Inch SDS-Hex 16 Amp Strong Power 1900 BPM 60 Joules Impact Energy 35 lb version of this hammer.First off - this gets the job done. We live in Austin and our backyard is peppered all over with lime-stone rocks. We can't even sink a screw-driver into the ground without hitting a lime-stone rock inside of 5-6 inches. When we want to make a real hole for planting or fencing, we'll hit a large lime-stone rock that will stop us cold. We have rented rock breakers in the past, but we've always wanted our own; this hammer meets the bill perfectly. Now I have to state that most of our rocks are 5-6" thick or less. And so far (today!) it has blasted through these with minimal effort. It will crack these into chunks that we can then manually pull out by hand.This really opens up our yard to a lot more landscaping opportunities.The case is the only downside as it is too weak to hold a tool this large & heavy. Not a huge show-stopper for us since we can carry the tool around the back or front yard on its own.Lastly, this does a good job reducing the jarring impact to the user but it still takes some down force to keep it from skipping which translates to vibration up to the user. The dampening here is as good or slightly better than hammers rented from home improvement outlets.Bottomline:Good tool for use around the home to break rocks and/or concrete. Case is great for storage, but is weakly designed and needs to be better.I'm just a DIY'er, so I can't attest to how this would hold up to heavy use. But for backyard projects, etc, this is terrific. No problems at all, it performs exactly as expected.There are some drawbacks to a midsized demolition hammer. On a larger jack hammer, I can stand up straight to use it, whereas on this smaller one, I have to bend over to use it. So it's some wear and tear on your back (this would be especially difficult if you're taller than me - it's a challenge even at 6 feet tall). I also have a 23 pound demolition hammer from harbor freight, and that one can be used on walls, can reach tight spots, I can crouch or sit down to use it. This Berserker 35 pound is less versatile.So make sure to look closely at your projected uses, and weigh the pros/cons of a smaller less expensive demo hammer, or of a larger unit.A couple complaints. First, the storage box has wheels, but it will not stand up on its own. Also, it arrived with oil spilled all over the inside of the storage case. I couldn't tell if the unit was leaking oil, but I suspect it was just the bottle of oil wasn't sealed well and spilled. However, after use, the hammer itself was also leaking a bit of oil.
