Review on 🌼 Proudly Snappy Spring-Loaded Centering by Robert Prix

The best invention! Works like a dream so glad I found this product. I replaced/replaced all of the interior doors in our house (10 doors from 24" to 32") so I had to both cut a recess for the hinges (two per door so 20 milling operations) and pre-drill holes for each hinge ( three per hinge, i.e. 60 drilling processes) plus pre-drilling of screw holes for the new door handle (two per door, i.e. 20 more holes). Not only did this set of self-centering drill bits make this task a lot easier, but as you know (if you've ever hung a new door on an existing door), you can do everything else perfectly as long as the hinge screw holes are off-center. , your door does NOT close properly. So definitely 5 stars for these drills.
