KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is the KEO 90° 1-flute countersink used for?

This KEO countersink creates 90° chamfered holes in metal, plastic, or wood. It is commonly used in machining and fabrication to deburr drilled holes or prepare countersunk screw seats. The single-flute design provides fast, chatter-free cutting in production environments.

What are the specifications of the KEO 919-000-597 countersink?

The KEO 919-000-597 is a 90° countersink with 1 flute, 1/8 in body diameter, and 1/8 in shank diameter. It is made from cobalt steel for heat resistance and durability. The single-flute geometry enables aggressive material removal in hard metals.

Where to buy the KEO 919-000-597 countersink worldwide?

3G Electric supplies the KEO 919-000-597 countersink worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time; we source and deliver this KEO tool to any country.

How to select the correct KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (90° for standard screw heads), body diameter matching the hole size, and shank diameter compatible with your tool holder. Cobalt steel is ideal for stainless steel or high-temperature alloys. Always match flute count to material hardness for optimal chip evacuation.
