The equipment looks to be well built for the purchase price, but I would consider it a tool for the DIY guy, but that's just my opinion. The provided paperwork does not really cover assembling the core drill, but its not hard to figure it out, just look at the exploded view in the back of the booklet. what is not identified is the needed Q.D. for the water line, for my application I needed an adapter for a 5/8\" fitting. I found that Gardena P/N 36918 works perfect and I found it at a local hardware store for $3.99.
