If you need a drill for drilling cement block, brick, cement board or plaster this is the one for you. I used to read a lot of reviews about carbide hole saws and a lot of people complain that they just smoke and get very hot when drilling into wood. I'm sure they do, they really aren't built for it. However, if you're drilling through any of the materials listed above, this bit is one of the best I've used. It lasts longer than many other brands. I know this because I've bought similar onesโฆ
