Frequently Asked Questions

What is the KEO 55458 countersink used for?

The KEO 55458 is a fast-cutting single-flute countersink designed for deburring and chamfering holes in metal. Its 110° angle and cobalt construction make it suitable for hard materials like stainless steel and tool steel in industrial machining and fabrication.

What are the specifications of the KEO 55458 countersink?

The KEO 55458 has a 1 3/4 in body diameter, 3/4 in shank, and a 110° included angle with one flute. It is made from cobalt steel, offering heat resistance and durability for high-speed cutting. The MPN is 55458.

Where to buy the KEO 55458 countersink worldwide?

3G Electric supplies the KEO 55458 countersink worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this cobalt single-flute countersink.

How to select the right KEO countersink for my application?

Choose the KEO 55458 for 110° chamfering in hard metals like stainless steel. Match the body diameter to your hole size and ensure the shank fits your tool holder. Cobalt material provides heat resistance for high-speed use. For softer materials, consider high-speed steel alternatives.
