Have this Bohrstops bought as very favorable and I actually needed sizes from 4 to 10 for a drilling project, this would not buy expensive individually (4p there are also rare ..). Since there are already reviews with reviews, heir my personal observations: When tightening the Bohrstops sit sometimes not exactly, but you can correct. It is correct, you fixed the depth stop with the screw on the saddle (!) Of the drill, not in recess. Then he does not slip even with multiple holes. Note: Unscrew the screw too far, they will fall out and may be difficult to recover.
My Conclusion: I was able to perform my entire multi-day drilling project without errors with these simple Bohrstops, without which I would have me at any point annoyed times. For the low price rarely obtained otherwise well Bohrstops 3-12 mm in one package. Considering the simple design, the price and my upshots of practice, I like to give 5 stars.
