Review on 🔧 Quality Performance: Gyros 45 11260 Carbon Steel Gauge - Accurate Measurement Tool by Cody Hunt

Don't waste your money on this; Spend a little more and get better quality - it makes the job a lot more enjoyable. I put one of these (#80) in my pin vise and attacked a pre-marked hole in styrene about .030 inch. Turn, turn, turn, turn, nothing came of it. Then I looked at it under my Optivisor. In fact, it looked clipped like you were using side cutters. Looking at the rest of the dozen, I found one (!) that seemed serviceable and worked well, not so well, and then it broke in half on 8 holes out of 24. I cannot recommend them.
