Frequently Asked Questions

What is the KEO 90° countersink used for?

The KEO 90° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its single-flute design provides fast, chatter-free cutting in materials like steel and aluminum, making it ideal for deburring and countersinking holes in industrial manufacturing.

What are the specifications of the KEO 919-000-099 countersink?

The KEO 919-000-099 is a 90° countersink with 1 flute, a 3/16 in body diameter, and a 3/16 in shank. It is made from high-speed steel (HSS) for durability. This fast-cutting single-flute countersink is designed for precision chamfering and deburring in metalworking.

Where to buy KEO countersinks worldwide?

You can source KEO countersinks worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead times on the KEO 919-000-099 or other KEO tooling.

How to select the right KEO countersink for your application?

Select a KEO countersink based on screw head angle (90° for standard flat-head screws), material (HSS for general steel, carbide for harder alloys), and shank size matching your tool holder. The single-flute design offers fast cutting; ensure body diameter exceeds screw head size for proper seating.
