Select a KEO countersink based on hole size, material, and desired chamfer angle. For standard 90° chamfers in steel or aluminum, the three-flute design provides balanced cutting and reduced chatter. Ensure the body diameter matches your tool holder. For harder materials, TiN coating improves wear resistance. Always match the countersink diameter to the fastener head size.
