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.

Where to buy KEO countersink 919-000-542 worldwide?

3G Electric supplies the KEO countersink 919-000-542 to customers worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your facility. Contact us for a quote and lead time on this precision cutting tool.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (e.g., 90° for standard flat-head screws), flute count for chip evacuation, and coating for material compatibility. For hard metals, TiN-coated cobalt tools like the 919-000-542 offer durability. Match body diameter to your drill press or CNC holder.
