Pros.I makes a nice clean hole. Much better than the Bosch bits I usually use, they are very light and don't take much force to drill a hole. Cons About 10 minutes after using the bit for the first time, I hit a nail. The nail completely removed one of the three points on the head. So I took my sharpener and tried to sharpen it. At this point I was able to get it to cut again, but now it takes a lot of effort to drill a hole. Many days later I'm still using the bit here and there and I've noticed that with some use the bit is now quite warped.
