Frequently Asked Questions

The KEO 919-000-378 is a 90°, 6-flute countersink used for deburring and countersinking holes in metal, plastic, and wood. Its TiN-coated high-speed steel construction provides wear resistance and extends tool life in production environments. The six-flute design delivers a smooth finish and reduces chatter during operation.
What are the specifications of the KEO 919-000-378 countersink?
The KEO 919-000-378 is a 90° countersink with a 5/16 in body diameter, six flutes, and a TiN-coated high-speed steel construction. It is designed for smooth-finish applications and is manufactured by KEO under part number 919-000-378. The TiN coating reduces friction and improves chip evacuation.

How to select the correct KEO countersink for your application?

Match the body diameter to your hole size and ensure the flute count suits your desired surface finish—six flutes provide smoother results than three-flute designs.
