Great tool! Worked good, I got the 1/2" adapter for it and it worked great drilling a 5" hole through my foundation for my radon system. Keep an eye on the temperature of your drill, I burned mine out in the first 15 minutes. The bit held up great, the drill did not. After 3 hours (stop and go) I was able to drill the hole. I found that it was hard to get it started but I traced the core bit with a sharpee and cut a Grove with an angle grinder (masonry grinding wheel) to get it started then used the core bit. The bit is a little expensive for something you will probably never use again but it holds up great and the hole was perfect. In the end it was cheaper than hiring someone to do it for me. I would definitely recommend this product.
