Customer Reviews
Be sure to get one of these: https://amzn.com/B01F4IQOE8 You will also need a decent (like 9+ amps) 1/2" corded electric drill. And one that drills at high speed - like 3000-4000 RPM. do NOT use a hammer drill, or if you do, be sure you can turn off the hammering. Drill dry at the hightest speed. It worked good once I got a decent drill. The bit still has the diamonds on it to be used for another day!
