Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 82° countersink used for?

The KEO 82° six-flute countersink is designed for deburring and countersinking holes in metal, plastic, and wood. Its 82-degree angle matches standard flat-head screw angles, making it ideal for aerospace, automotive, and general fabrication where a smooth finish is required.

What are the specifications of the KEO 919-000-340 countersink?

The KEO 919-000-340 is an 82° countersink with six flutes, a 5/16 in body diameter, and is made from high-speed steel. It is part of KEO's Smooth-Finish Six-Flute Countersinks line, designed for clean, chatter-free operation in production environments.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-340 to customers worldwide. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver globally.

How to select the right KEO countersink for my application?

Select a KEO countersink based on the screw head angle (82° for flat-head screws), material (high-speed steel for general use), and flute count (six flutes for smoother finish). Match the body diameter to your hole size. For hard materials, consider carbide options.
