Frequently Asked Questions

What is the KEO 82° countersink used for?

The KEO 82° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its four-flute design provides smooth cutting and reduced chatter, making it suitable for production environments where consistent countersink depth and finish are required.

What are the specifications of the KEO 919-000-010 countersink?

The KEO 919-000-010 is an 82° four-flute machine countersink with a 3/4 in body diameter. It features a TiN-coated high-speed steel construction for wear resistance and extended tool life. This tool is designed for use in drill presses and CNC machines for precision countersinking in ferrous and non-ferrous materials.

Where to buy KEO countersinks worldwide?

How to select the correct KEO countersink size?

Select the KEO countersink based on the screw head angle and body diameter needed for your application. For flat-head screws, match the countersink angle (82° for inch-series screws) and choose a body diameter slightly larger than the screw head. Ensure the tool's flute count and coating suit your material and production volume.
