Worked very well for drilling an 18" hole in 8" thick concrete. The tip of one of the smaller nozzles melted, but overall it worked and I'm happy with it. I had an offer for $1200. This kit saved me money since I could do it myself. It took about 40 seconds to drill through 8-inch concrete with these bits.
