Frequently Asked Questions

What is a KEO 6-flute countersink used for?

A KEO 6-flute countersink creates a smooth, conical recess for flat-head screws in metalworking. The six-flute design reduces chatter and produces a finer finish than standard countersinks. It is commonly used in aerospace, automotive, and general machining applications where a clean, burr-free countersink is required.

What are the specifications of the KEO 55081-TIN countersink?

The KEO 55081-TIN is a 110° countersink with 6 flutes, a 3/16 in body diameter, and a 3/16 in shank. It is made from TiN-coated high-speed steel for increased wear resistance and tool life. This smooth-finish countersink is designed for precision chamfering in ferrous and non-ferrous materials.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 110° for flat-head screws), material hardness, and desired finish. For harder materials, choose TiN-coated high-speed steel like the 55081-TIN. Match the body diameter to the screw head size and ensure the shank fits your tool holder. Consult a machining handbook for optimal speeds and feeds.
