I'm getting better but I'm pretty picky about drill bits so buying cheap drill bits costs me more. I came across Champion cutting tools and am very impressed with the quality of these bits. I have drilled holes in a 2 1/4 diameter oil field tubular and am still on the first drill after 68 holes. It shows some wear, but still cuts through like wood. A couple of times the drill got stuck and yanked the drill out of his hand. Any other drill would have broken. I have several sizes from this brand and they are all similar to this review. Save money and try them and you will regret not doing it years ago.
