Beautiful Bit - my new review

I needed a unique size bit for a special project, but could not find one locally. Assumed a mail order bit was not likely to be of the best quality, but I was pleasantly surprised to see the quality and have to function perfectly. I thin it will last longer than my use for it will last. That means I'll never have to buy a replacement.

Pros
  • Drilled 30 holes through 3/8" steel tube without any issues.
Cons
  • Broke when I was drilling the 2nd hole. I have so many drills and none broke in 2nd hole.
