Frequently Asked Questions

What is the KEO 55016 countersink used for?

The KEO 55016 is a 60° six-flute countersink used to create smooth, chamfered holes in metal for screw heads or deburring. It is common in machining, tool-and-die, and fabrication shops where a fine finish is required on steel or non-ferrous materials.

What are the specifications of the KEO 55016 countersink?

The KEO 55016 is a 60° countersink with six flutes, a 2 1/2 in body diameter, and a 1 in shank. It is made from high-speed steel (HSS) and is designed for smooth-finish applications. The manufacturer part number is 55016.

Where to buy the KEO 55016 countersink worldwide?

3G Electric supplies the KEO 55016 countersink worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this KEO tool to any country.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (e.g., 60° for standard screw heads), material (HSS for general metal), and size. The 55016 has a 2 1/2 in body diameter and 1 in shank, suitable for larger holes. Match flute count to finish quality—six flutes provide a smoother finish than fewer flutes.
