How to select the right KEO countersink for your application?

Select a KEO countersink based on hole angle, material, and shank size. For standard screw heads, a 90° angle like the 917-000-300 is common. Match the body diameter to the hole size and ensure the shank fits your tool holder. TiN coating is recommended for ferrous metals to reduce friction and extend tool life.
