Product Description

KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

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

This KEO countersink creates 90° chamfered holes in metal, plastic, or wood for deburring and screw-head seating. Its single-flute design cuts fast with minimal chatter, making it ideal for production machining and maintenance work across industrial departments.

What are the specifications of the KEO 919-002-897 countersink?

The KEO 919-002-897 is a 90° countersink with 1 flute, 1/4 in body diameter, and AlTiN-coated high speed steel. The AlTiN coating extends tool life on abrasive materials. It is designed for fast, single-flute cutting in general industrial applications.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-002-897 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact our team for a quote and lead time on this single-flute, 90° countersink with AlTiN coating.

How to select the right KEO countersink for your application?

Match the countersink angle (90° for standard screw heads) and body diameter to your hole size. For harder materials, choose AlTiN-coated high speed steel like this KEO model. Single-flute designs are best for fast, chatter-free cutting in production environments.
