Review: the best quality - KEO`s stuff is an industry standard as far as I`m concerned. I`ve used their countersinks for years in every machine shop I ever worked in ,so when I saw this on desertcart for a decent price I grabbed it for my home shop knowing it will last beyond me !
Review: Disappointed - It came in a red case not in the picture that shows the nice wooden stand! False advertising and nowhere does it say made in USA! what a joke
