Great hammer for the price. I have a Bosch rotary drill/hammer that is great for small jobs but had a bigger job cutting and removing concrete for channel drains in a customers garage. The big hammers are a minimum of $600 up to $2,000. This was easy to handle compared to a 80pound hammer and easily broke up 40 feet of 4" thick concrete for removal. Had to be broken in to smaller pieces for removal and did a great job.
It is an odd shaft size so not much for extra bits but the 2 that came with it were all i needed
