Review on 🔧 Optimized Preamer Industrial Countersink: Enhancing Working and Deburring Efficiency by Brandon Plowden

As per other reviews it appears to be a series of countersinking errors. Only 2 sizes marked. The sizes seem to be randomly packed. Yes there are 5 bits listed but two of them are 1/2", one is probably 12mm, the largest is 16mm and the smallest is "about" 3/8" as only two are marked. Cut? Mediocre. I will sharpen and hone on a grinder.
