Frequently Asked Questions

What is a KEO 6-flute countersink used for?

The KEO 120° 6-flute countersink is used for deburring and countersinking holes in metal, producing a smooth finish. It is ideal for machining, fabrication, and maintenance applications where precise chamfering is required on steel, stainless steel, and other materials.

What are the specifications of the KEO 919-000-891 countersink?

The KEO 919-000-891 is a 120° countersink with 6 flutes, a 3/4 in body diameter, and is made from cobalt steel. It is designed for smooth-finish countersinking and is suitable for use in industrial machining and metalworking operations.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-891 to customers worldwide. We handle full logistics, customs clearance, and delivery to your location. Contact us for pricing and lead time on this and other industrial cutting tools across 14 departments.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required angle (e.g., 120°), flute count for finish quality, body diameter to match hole size, and material compatibility. Cobalt steel versions like the 919-000-891 offer heat resistance for harder metals. Consult your application specs for best results.
