Review on 💯 Amana Tool Countersink with Adjustable Depth Stop: Achieve Precise and Consistent Sink Depths by Bruce Marable

This is a great way to drill and countersink screw heads in one movement. It is easily adjustable and comes with a double ended hex key for adjustment. I have been using Microstop countersinks on aircraft sheet metal for over 40 years. They are adjustable in increments of 0.002. I still have a few micro stops and can use 82 degree bits but they don't pre-drill. These are excellent wood sinkers. Just adjust the sinking depth to scrap wood and enjoy the precision.
