Frequently Asked Questions

What is the KEO 55593-TiN countersink used for?

The KEO 55593-TiN countersink is used for creating 110° chamfered holes in metal, plastics, and composites. Its six-flute design produces a smooth finish, while the TiN-coated cobalt body resists wear and heat. Common applications include aerospace, automotive, and general machining where precise countersinking is required.

What are the specifications of the KEO 55593-TiN countersink?

The KEO 55593-TiN countersink has a 110° included angle, six flutes, a 1 1/2 in body diameter, and a 3/4 in shank. It is made from TiN-coated cobalt steel. The manufacturer part number is 55593-TiN, and it is designed for smooth-finish countersinking in industrial machining operations.

Where to buy the KEO 55593-TiN countersink worldwide?

You can source the KEO 55593-TiN countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this tool to machining facilities and maintenance teams internationally.

How to select the correct KEO countersink for a job?

To select the correct KEO countersink, match the included angle (e.g., 110°) to your fastener's head angle. Choose body diameter and shank size to fit your tool holder. For hard materials, opt for TiN-coated cobalt like the 55593-TiN. Always verify the flute count—six flutes provide smoother finishes than three-flute designs.
