Product Description

KEO General Purpose Three-Flute Countersinks.

Frequently Asked Questions

What is the KEO 60° countersink used for?

The KEO 60° countersink is used for deburring and countersinking holes in metal, plastic, and wood. Its three-flute design provides smooth, chatter-free operation, making it ideal for general-purpose machining in industrial fabrication and maintenance applications.

What are the specifications of the KEO 60° countersink?

The KEO countersink has a 60° included angle, three flutes, and a 1/4 in body diameter. It is made from cobalt steel (MPN 917-000-157) for durability in hard materials. This general-purpose tool is suitable for precision countersinking in metalworking.

Where to buy the KEO 60° countersink worldwide?

You can source the KEO 60° countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring reliable supply for your machining needs.

How to select the right KEO countersink for your application?

Select the KEO 60° countersink based on material hardness and hole size. For steel or stainless steel, the cobalt construction offers heat resistance. Match the body diameter (1/4 in) to your drill chuck capacity. Always use proper cutting fluid to extend tool life.
