Review on Vix Bit 3VIXBIT Centering Pre Drill - Achieve Accurate Drilling with 64 Inch Precision by Brent Ayyagari

If you've ever installed hinges, drawer slides, latches, etc. these are great. The screw hole is in the middle of the hole, and the built-in part looks much more professional than with amateurishly turned screws. There is also a depth adjustment to avoid drilling through the sides of suitcases, the sides of drawers and the like. .Wood shavings can sometimes prevent the tool from retracting and it's annoying, but there's no way to prevent it and you'll get used to pulling it out by hand when needed. The usefulness of the tool far outweighs this small issue.
