Frequently Asked Questions

What is a KEO 55086-TIN countersink used for?

The KEO 55086-TIN countersink is used for deburring and chamfering holes in metal, creating a smooth 110° countersink for screw heads. Its six-flute design and TiN coating reduce chatter and extend tool life in production machining, automotive, and aerospace applications.

What are the specifications of the KEO 55086-TIN countersink?

The KEO 55086-TIN is a 110°, six-flute countersink with a 1/2 in body diameter, made from TiN-coated high-speed steel. It is designed for smooth-finish countersinking in ferrous and non-ferrous materials, offering durability and consistent performance.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 55086-TIN to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. 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 hole angle (e.g., 110° for standard screws), flute count for finish quality, and coating for material type. The 55086-TIN with TiN coating suits harder metals. Match body diameter to your tool holder and workpiece size for optimal results.
