Frequently Asked Questions

What is the KEO 55349 countersink used for?

The KEO 55349 is a general-purpose three-flute countersink used for deburring and chamfering holes in metal. Its 110° angle and cobalt construction suit machining of hardened steels and alloys. Common applications include automotive, aerospace, and general fabrication where precise countersinking is required.

What are the specifications of the KEO 55349 countersink?

The KEO 55349 countersink has a 110° included angle, three flutes, a 2-inch body diameter, and a 3/4-inch shank. It is made from cobalt steel for heat resistance and durability. The manufacturer part number is 55349, and it is designed for general-purpose countersinking in metalworking.

Where to buy the KEO 55349 countersink worldwide?
