Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is used to create a smooth, chamfered recess for flat-head screws in metalworking and fabrication. Its six-flute design and TiN coating reduce chatter and extend tool life, making it suitable for production environments requiring consistent finish quality.

What are the specifications of the KEO 919-000-419 countersink?

The KEO 919-000-419 is a 100° countersink with six flutes, a 1/2 in body diameter, and TiN-coated high-speed steel construction. It is designed for smooth-finish applications and is manufactured by KEO under MPN 919-000-419.

Where to buy the KEO 919-000-419 countersink worldwide?
