Price point is great. Motor is strong. Clutching is pretty good. No water leaks and it's nice to have a water valve at the drill. So far, we've drilled a few 17" and 18" deep holes through some serious stone. For the 18", we got in about 6" and chipped out an inch or two of the core. No headaches or fear of failure so far. Having two levels on the unit is also pretty nice.

Very strong drill. Don't assume all hose connections are tight out of the box. Tighten them yourself.

I purchased this drill kit to drill holes thru stem walls for plumbing pipe and it works well. Does require a steady hand and some physical strength but it's not hard to use. I do wish the bits were built to accomadate plumbing pipe. You must use the 3" bit to install 2" pipe due to the pipe walls actual O.D. size.

We use this cord drill instead of our largerr set up for smaller holes and it works very well on thin concrete floors 3 1/2†to 6†in commercial buildings

Piece of junk broke first time I tried to drill a hole in brick wall. Wasn't even a center block wall

Handle is plastic even though the rest of the tool is steel. I also did not get the option to return after handle broke. Terrible drill and customer service from seller.
