Reviews

"These work GREAT!"

"Definitely glad I upgraded to cobalt steel countersinks."

"Finally found this set of quality cobalt steel countrrsinks for metal and wood."

".5 Star deduction for me having to de-burr the cutting edge with a small roll of fine sandpaper."

"I user these on aluminum plate to countersink a bunch of screw holes and they work fantastic."

"Very well made and effective."

"My feelings are KEO- If you cant spend 5 extra minutes to take burs off and make sure the cutting edges are sharp, I will find someone who will. In fact this is why I wanted a set from Keo- to have a nice sharp set that I could use and I got basically the same thing as the inexpensive chinese set my friend has. If Keo had cared, they would have asked me to send them in, offered to send me a set that was checked and double checked,\. and then --when receiving the set I sent them, would have done whatever to correct."
