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 Amazon for a decent price I grabbed it for my home shop knowing it will last beyond me !

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

been using them for a short bit now and they work great. Keep your speed nice and slow with good lube and these should hold up for a long time.

We have recently gotten a set of these for use in the Maintenance shop at work. I used the 3/4" Saturday on food grade stainless steel...WOW! These are great! I'm buying a set for myself today! The American made quality is top notch!
