KEO Anti-Vibration Zero-Flute Countersinks.

Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink is used to create a conical recess for flat-head screws in metalworking. This zero-flute design reduces vibration and chatter, producing a smoother finish. It is commonly applied in machining and fabrication across industries like automotive and aerospace.

What are the specifications of the KEO 919-000-242 countersink?

The KEO 919-000-242 is a 100° countersink with a 5/8 in body diameter, zero flutes, and cobalt construction. It is designed for anti-vibration performance in hard materials. The manufacturer part number is 919-000-242, and it is made by KEO.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-242 to customers worldwide. We handle full logistics and customs clearance for global delivery. Contact us to source this tool for your industrial operations, ensuring you get the right part for your application.

How to select the right KEO countersink for metalworking?

Select a KEO countersink based on screw head angle and material. For hard metals, choose cobalt or carbide. The 100° angle suits standard flat-head screws. Match body diameter to your workpiece. Zero-flute designs reduce chatter, improving finish in precision machining.
