Frequently Asked Questions

What is the KEO 919-002-343 countersink used for?

The KEO 919-002-343 is a 90°, single-flute countersink designed for deburring and countersinking holes in metal, plastic, and composite materials. Its AlTiN-coated carbide construction provides heat resistance and extended tool life in production environments. It is commonly used in machining, automotive, and aerospace applications.

What are the specifications of the KEO 919-002-343 countersink?

The KEO 919-002-343 is a 90° countersink with 1 flute and a 5/8 in body diameter. It features an AlTiN-coated carbide tip for wear resistance. The manufacturer part number is 919-002-343. This fast-cutting single-flute design is optimized for clean, efficient countersinking in ferrous and non-ferrous materials.
