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 for deburring or screw-head seating. Its single-flute design cuts fast with minimal chatter, ideal for production machining, tool-and-die work, and general fabrication across industrial departments.

What are the specifications of the KEO 919-000-598 countersink?

The KEO 919-000-598 is a 90° single-flute countersink with a 1/8 in body diameter and 1/8 in shank. It features a TiN-coated cobalt construction for wear resistance. This tool is designed for fast, clean countersinking in ferrous and non-ferrous materials.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-598 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 tool.

How to select the right KEO countersink for my application?

Match the countersink angle (90° for standard flat-head screws) and body diameter to your hole size. For hard metals, choose TiN-coated cobalt like this KEO model. Single-flute designs suit high-speed production; multi-flute options provide smoother finishes on softer materials.
