Customer Reviews for Demolition Jack Hammer Concrete Breaker 2100W Electric Hammer 2 Chisel Bit

Great jackhammer for the price. I already have 2 neighbors ready to buy one!

Used this for 8 hrs three days in a row busting out concrete. Loosening boulders out of concrete perches; breaking stem wall around rebar. Must add oil before use, and I greased up the chistle on the machine end. One review said it hammers for a bit and then just vibrates. Happened to me as well, I just gave it a little more down pressure or raised and rammed it home again. This thing is a beast. Highly recommend. Hundred bucks cheaper than Harbor Freight and Lowes and the delivery was actually a bit early.

Paid for itself the first job

I was reluctant to buy an off-brand overseas product. No directions came with the unit. Just remember to put machine oil in it before use.I am digging for an outdoor patio. Hit a boulder the size of my wife's sedan. The weekly price to rent a demo hammer was more than the cost of this tool. This demo hammer chewed through solid black shale in Northeast PA like it was nothing.Works great.

Made short work of an old concrete block wood stove in basement. Make sure you use heavy extension cord and don’t forget to add oil!!! (this thing ships dry for shipping reasons so don’t run without oil!!!)

This jack hammer is the right weight. It lets me fracture 9” thick Tennessee lime stone rocks. I have cleared out almost 5000 lbs of rock and dirt.

The tool works well and cuts through concrete without any problem. It is heavy and requires some effort to handle. It requires heavy weight hydraulic oil, which was not provided, and although it doesn't require much the smallest container I could find was 1 gallon. The operating manual is too general and written for multiple tools, but the tool is not complicated to understand or use so it is not a big deal if you have some general understanding of power tools. Overall it is very effective, and for the price an outstanding value.
