Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its zero-flute design minimizes vibration and chatter, producing a smooth finish. The AlTiN coating on cobalt steel extends tool life when cutting hardened steels or abrasive materials.

What are the specifications of the KEO 919-002-819 countersink?

The KEO 919-002-819 is a 100° countersink with a 5/16 in body diameter, zero flutes, and an AlTiN-coated cobalt construction. It is designed for anti-vibration performance in industrial machining. The manufacturer part number is 919-002-819, and it is made by KEO.

Where to buy the KEO 919-002-819 countersink worldwide?

How to select the correct KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 100° for flat-head screws), body diameter matching the screw size, and coating for material hardness. For hardened steels, choose AlTiN-coated cobalt. Ensure the zero-flute design is used for vibration-prone setups to achieve a clean countersink.
