Frequently Asked Questions

What is the KEO 120° countersink used for?

The KEO 120° countersink is designed for creating chamfered holes in metal, plastic, or wood. Its three-flute design provides smooth cutting and reduces chatter, making it ideal for deburring and countersinking screw heads in general manufacturing and maintenance applications.

What are the specifications of the KEO 917-000-930 countersink?

The KEO 917-000-930 is a 120° countersink with three flutes and a 1 1/4 in body diameter. It features AlTiN coated high speed steel for extended tool life and heat resistance. This general-purpose tool is suitable for use on ferrous and non-ferrous materials.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (e.g., 120° for flat-head screws), material type, and hole size. The three-flute design offers better chip evacuation than two-flute versions. For hard materials, choose AlTiN coated high speed steel for improved wear resistance.
