I have to give this drill ZERO stars. Worst drill I have ever put in a drill chuck. The drill bit itself is bent about 1/64 inch. It works fine on the shaft in the lining, it comes out about 0.03 inch at the tip. Luckily I only dreamed of a 3/4 layer hole. I was able to get the job done, but this exercise is complete rubbish. DO NOT SPEND YOUR CASH!
