Product Description

KEO General Purpose Three-Flute Countersinks.

Frequently Asked Questions

What is a KEO 3-flute countersink used for?

A KEO 3-flute countersink creates a 90° chamfer around a drilled hole, allowing screw heads to sit flush with the workpiece surface. It is commonly used in metalworking, machining, and fabrication for deburring and preparing holes for fasteners.

What are the specifications of the KEO 917-000-199 countersink?

The KEO 917-000-199 is a general-purpose three-flute countersink with a 90° included angle and a 3/8 in body diameter. It is made from cobalt steel for heat resistance and durability in ferrous and non-ferrous materials.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 917-000-199 to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this cobalt three-flute tool.

How to select the right KEO countersink size?

Select a KEO countersink with a body diameter larger than the screw head you are countersinking. For a 90° countersink, match the angle to the fastener's head angle. Cobalt flutes suit harder materials like stainless steel, while high-speed steel works for aluminum.
