Frequently Asked Questions

What is the KEO 55782-TiALN countersink used for?

The KEO 55782-TiALN is a 60°, 6-flute countersink designed for creating smooth, burr-free chamfers on drilled holes in metal. Its TiAlN coating extends tool life in hardened steels and alloys. Common applications include aerospace, automotive, and general machining where precision countersinking is required.

What are the specifications of the KEO 55782-TiALN countersink?

This KEO countersink has a 60° included angle, 6 flutes, and a 1/4 in body diameter. It is made from TiAlN-coated carbide for wear resistance. The manufacturer part number is 55782-TiALN. It is designed for smooth-finish countersinking in ferrous and non-ferrous materials.

Where to buy the KEO 55782-TiALN countersink worldwide?

3G Electric supplies the KEO 55782-TiALN countersink to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact our team for pricing and lead time. As a global industrial distributor, we source and deliver this KEO tool to any location.

How to select the correct KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (60° for standard screw heads), material hardness (TiAlN coating for steels), and hole size. The 6-flute design provides smoother finishes than 3-flute tools. Match the body diameter to your drill chuck capacity. Consult KEO's catalog for specific material recommendations.
