Frequently Asked Questions

What is the KEO 55459-TiN countersink used for?

The KEO 55459-TiN is a fast-cutting single-flute countersink designed for deburring and chamfering holes in metal. Its 110° angle and TiN-coated cobalt construction suit high-speed machining on steel, stainless steel, and other hard materials in industrial manufacturing and fabrication.

What are the specifications of the KEO 55459-TiN countersink?

The KEO 55459-TiN has a 110° included angle, 1 flute, 2 in body diameter, and 3/4 in shank. It is made from cobalt with a titanium nitride (TiN) coating for wear resistance. This single-flute design provides fast cutting and chip clearance for precision countersinking.
