Frequently Asked Questions

What is the KEO 919-002-339 countersink used for?

The KEO 919-002-339 is a 90°, single-flute countersink designed for fast, clean chamfering and deburring of holes in metal. Its AlTiN-coated carbide body provides heat resistance and extended tool life in production environments. Common applications include aerospace, automotive, and general machining where precise countersinking is required.

What are the specifications of the KEO 919-002-339 countersink?

The KEO 919-002-339 is a 90° countersink with a single flute and a 3/8 in body diameter. It features an AlTiN-coated carbide construction for durability and heat resistance. The tool is designed for fast cutting and is suitable for use in CNC and manual machines. The manufacturer part number is 919-002-339.

Where to buy the KEO 919-002-339 countersink worldwide?
