Frequently Asked Questions
What is a KEO 4-flute countersink used for?
A KEO 4-flute countersink creates a 90° chamfer or countersink hole in metal, plastic, or wood. It is commonly used in machining and fabrication to prepare holes for flat-head screws or deburr edges. The TiN-coated cobalt construction provides heat resistance and longer tool life in industrial applications.
What are the specifications of the KEO countersink 919-000-542?
The KEO countersink model 919-000-542 has a 90° included angle, 4 flutes, a 5/8 in body diameter, and a TiN-coated cobalt finish. It is designed for machine use and is suitable for ferrous and non-ferrous materials. The TiN coating reduces friction and extends cutting performance.
