What is a 100 degree cobalt countersink most commonly used for?”
KEO Cutters has replicated its popular line of single and six flute countersinks as well as its three and four flute center reamers. All of the current HSS tools in these categories are now available in a more heat-resistant cobalt substrate. When you require a chamfer on an existing hole, look to KEO Cutters to provide the most cost effective solution! From the single flute workhorse tool to the finer finishing six flute countersink, the added durability of the cobalt substrate gives you just the little “extra” you need for the tougher applications you face. Machine countersinks are available as well for larger diameters. Three and four flute center reamers will cover a variety of piece part work materials just like the HSS.
