Frequently Asked Questions

What is a KEO 60° countersink used for?

A KEO 60° countersink creates a smooth, chamfered recess for flat-head screws in metalworking and machining applications. Its six-flute carbide design produces a fine finish and reduces chatter, making it ideal for precision deburring and countersinking in industrial manufacturing.

What are the specifications of the KEO 919-000-991 countersink?

The KEO 919-000-991 is a 60° countersink with six flutes, a 3/16 in body diameter, and a 3/16 in shank. It is made of carbide for durability and is part of KEO's Smooth-Finish Six-Flute Countersinks line, designed for clean, chatter-free operation.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-991 to customers worldwide. We handle full logistics, customs clearance, and delivery, ensuring you receive genuine industrial tooling. Contact us for pricing and lead time on this and other KEO cutting tools.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (60° for standard flat-head screws), material (carbide for hard metals), and shank size matching your tool holder. The six-flute design provides a smoother finish than standard three-flute tools, reducing secondary deburring steps.
