How to select the right KEO countersink for your application?
Choose a KEO countersink based on hole angle (e.g., 120°), material (cobalt for hard metals), and shank size matching your tool holder. For smooth finishes on steel or stainless, a six-flute design reduces chatter. Confirm body diameter clears the workpiece and that RPM matches tooling recommendations.
