Frequently Asked Questions

What is the KEO 120° countersink used for?

The KEO 120° countersink is used for deburring and countersinking holes in metal, plastic, and wood. Its 120° included angle suits countersinking for flat-head screws and rivets. The three-flute design provides smooth cutting and reduced chatter, making it ideal for general-purpose machining in industrial fabrication and maintenance.

What are the specifications of the KEO 917-000-120 countersink?

The KEO 917-000-120 is a 120° countersink with three flutes, a 1 1/2 in body diameter, and a 3/4 in shank. It is made from TiN-coated high-speed steel for wear resistance. This general-purpose tool is designed for use in drill presses and handheld drills, providing clean, accurate countersinking in various materials.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle—120° for flat-head fasteners. Match the body diameter to the hole size and the shank to your tool holder. For harder materials, choose TiN-coated high-speed steel like the 917-000-120. Ensure the flute count suits your material: three flutes reduce chatter in metals.
