Frequently Asked Questions

What is a KEO 60° countersink used for?

A KEO 60° countersink with six flutes creates smooth, chatter-free chamfers on drilled holes for fastener seating. It is commonly used in metalworking, aerospace, and automotive applications where a precise 60° angle and fine surface finish are required.

What are the specifications of the KEO 919-002-990 countersink?

The KEO 919-002-990 is a 60°, six-flute countersink with a 1/4 in body diameter. It features TiN-coated carbide construction for extended tool life and is designed for smooth-finish chamfering in ferrous and non-ferrous materials.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-002-990 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this TiN-coated carbide tool.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (60° for standard fastener heads), flute count (six flutes for smoother finish), body diameter matching hole size, and coating (TiN for heat resistance). Match material type to carbide grade for optimal tool life.
