Review on 🔩 1877793 IRWIN Metal Countersink Drill by Kirt Phillips

Bought these to sink wood. In this they fail completely. In any tree, at any speed, they wobble and wobble so much that they create a subsidence that is actually a hex. Totally useless. In addition, they are packed in a suitcase, which is also useless. They're so tight you'll need a screwdriver to pry them out. Then when you try to get them back they take so much trouble that you don't have to worry about throwing the suitcase away. If you're going to use it on a tree, do yourself a favor and get the KEO 53512. It costs more but is a lot better.
