Frequently Asked Questions

What is a KEO 90° single-flute countersink used for?

This KEO countersink creates clean 90° chamfers and countersinks in metal, plastic, and composite materials. Its single-flute design provides fast, chatter-free cutting, making it ideal for deburring holes and preparing surfaces for flat-head screws in machining and fabrication applications.

What are the specifications of the KEO 919-002-977 countersink?

The KEO 919-002-977 is a 90° countersink with 1 flute, a 3/4 in body diameter, and TiN-coated carbide construction. The TiN coating reduces friction and extends tool life. It is designed for fast cutting in industrial machining operations.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-002-977 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other KEO cutting tools.

How to select the right KEO countersink for your application?

Match the countersink angle (e.g., 90°) to your fastener head angle. Choose body diameter larger than the hole. For harder materials, select TiN-coated carbide like this KEO model for longer tool life. Single-flute designs work best for fast, chip-free cutting in production runs.
