Review on Adjustable Tapered Countersink - FTG USA by Justin Torres

Unfortunately I returned the product when I was told it was not rated for a standard #6 screw. The screw guide hole is too big for the #6 screw, the screw will fall out of the hole. Countersink is said to be .3125" and this product has a .372" hole. The 5/16" wooden plug will fall out of the hole. Custom design. I believe this is a metric product and is being mislabeled as a US size. Do not purchase if you have a standard #6 pilot hole and counter want.Wasted a lot of time and put me back on my project.
