Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is a KEO 6-flute countersink used for?

The KEO 6-flute countersink is used to create a smooth, chamfered recess for flat-head screws in metalworking. Its six-flute design reduces chatter and vibration, producing a clean finish in materials like steel and aluminum. Ideal for precision machining and fabrication applications.

What are the specifications of the KEO 919-000-733 countersink?

The KEO 919-000-733 is an 82°, 6-flute countersink with a 1/4 in body diameter, made from cobalt steel. It is designed for smooth-finish countersinking in hard materials. The cobalt construction provides heat resistance and durability for extended tool life in industrial use.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-733 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial solutions provider, we source genuine KEO tooling and support your procurement needs across all regions.

How to select the right KEO countersink for your application?

Select a KEO countersink based on screw head angle (82° for flat-head screws), flute count for finish quality, and material compatibility. Cobalt versions suit harder metals. Match body diameter to your drill chuck capacity. For best results, use proper cutting speed and lubrication per the workpiece material.
