Frequently Asked Questions
What is a KEO 110° single-flute countersink used for?
A KEO 110° single-flute countersink is used to create a conical recess in a workpiece, typically for a flathead screw or bolt. The 110° angle is common in aerospace and sheet-metal applications. KEO's TiN-coated high-speed steel design provides wear resistance for consistent, chatter-free countersinking in ferrous and non-ferrous materials.
What are the specifications of the KEO 53221-TIN countersink?
The KEO 53221-TIN is a 110° single-flute countersink with a 1 1/2 in body diameter and a 3/4 in shank. It is made from TiN-coated high-speed steel for extended tool life. This fast-cutting design is ideal for precision chamfering and deburring in industrial machining operations.
