Frequently Asked Questions
What is a KEO 6-flute countersink used for?
A KEO 6-flute countersink creates smooth, chatter-free 60° chamfers and countersinks in metal, plastic, and wood. The six-flute design reduces vibration for a finer finish than standard 3-flute tools, ideal for precision deburring and preparing holes for flat-head fasteners in industrial machining.
What are the specifications of the KEO 919-000-304 countersink?
The KEO 919-000-304 is a 60° countersink with 6 flutes, a 5/16 in body diameter, and TiN-coated high-speed steel. The TiN coating increases hardness and lubricity for longer tool life in ferrous and non-ferrous materials. It is designed for smooth-finish applications.

How to select the right KEO countersink for your application?
Select a KEO countersink based on the required chamfer angle (60° for standard flat-head screws), flute count (6-flute for smoother finish), body diameter matching your hole size, and coating (TiN for longer life in abrasive materials). Match RPM and feed rate to the workpiece hardness for best results.
