Frequently Asked Questions
What is the KEO 60° countersink used for?
The KEO 60° countersink is used for deburring and countersinking holes in metal, wood, and plastic. Its 60° included angle and four-flute design provide smooth, chatter-free cutting. Common applications include aerospace, automotive, and general machining where precise chamfering is required.
What are the specifications of the KEO 919-000-524 countersink?
The KEO 919-000-524 is a 60° four-flute machine countersink with a 3/4 in body diameter. It features a TiN (titanium nitride) coating on cobalt steel for extended tool life and heat resistance. This design is ideal for high-speed machining and produces clean, burr-free edges.

How to select the right KEO countersink for my application?
Select a KEO countersink based on the required chamfer angle (e.g., 60°, 82°, 90°), material hardness, and hole size. For steel or stainless steel, choose a TiN-coated cobalt version like the 919-000-524 for heat resistance. Match the body diameter to your toolholder and ensure the flute count suits your feed rate.
