This tool is very similar to a good air hammer used in automotive, it come with a pointy and spade bit. I am using this to install plants in the Sacramento area, while new to me, I found you cannot dig a few inches without hitting various rocks, from small stones to basketball size. This tool saves a lot of time trying to use a shovel to break through the rocks. It will chip off some of the rocks but on small \"boulders\" it will just scratch and not break them, this still allows to loosen the soil around and remove the tiny boulder. I have seen the landscapers have a bigger electric \"standing\" style with a big spade and they seem to be able to break them apart. On the Nevada side I have seen similar rocky backyard exists where I have watched them work and had to use a jackhammer almost with each hole they dig. I find it is best to push the pointy bit into the dirt and then tilt the tool, it will loosen up, repeat until it is full of holes, and then shovel the dirt and rocks out. I can tell you it is still very time consuming and exhausting for a size 15 \"15 gallon\" plants which is very popular here, takes about an hour to dig such a hole by hand and maybe about half the time aid of this tool. I only wish the bit is longer since as the hole get deeper, the reach can be awkward, but doable. 100% wear full goggles because chips will fly everywhere, and close your mouth. (Dust wasn't bad in my use) The best thing is the price, it is economical I am not too worried about grease and stuff, it comes with some grease but not clear how to use it, if it breaks I would buy it again.

Great tools well worth the money

I love this. Perfect for breaking up concrete. Nice case and excessories.

I added 4 stars only because the case that I have received was damaged and was not closing firmly. On the other hand, the tool itself is perfect for home use. I used it to break concrete, I did it so easily, it saved me days of work with the hammer. For thus price I would strongly recommend it.

ten points

Love it

Easily assembled and strong machine. It is light compared to its power. However, the chisels are not standard SDS fittings, so only the original short shafts that come with the machine can be used.

Incredibly cheap considering its power. The piercing machines of acquaintances were just toys compared to this, NS brand machines. It's worth checking the joule count when purchasing. No experience with durability yet.

As a demolition hammer, it feels light and a bit flimsy, but once you start working, things happen and results are produced, effective despite its lightness.

Works very well. I have ripped up a bathroom floor with built-in pipes. Just strong enough to be able to chisel away the concrete without breaking the pipes. Now the chisel is worn out, but the machine works well.
