KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 55617-TiN countersink used for?

The KEO 55617-TiN is a 120° six-flute countersink designed for producing smooth, burr-free chamfers on drilled holes in metal. It is commonly used in machining and fabrication for deburring and countersinking operations on steel, stainless steel, and other alloys.

What are the specifications of the KEO 55617-TiN countersink?

The KEO 55617-TiN has a 120° included angle, six flutes, a 3-inch body diameter, and a 1-inch shank. It features a titanium nitride (TiN) coating on cobalt steel for enhanced wear resistance and is manufactured by KEO under part number 55617-TiN.

Where to buy the KEO 55617-TiN countersink worldwide?

3G Electric supplies the KEO 55617-TiN countersink worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select the correct KEO countersink for your application?

Select a KEO countersink based on hole diameter, material, and desired finish. For hard metals, choose a TiN-coated cobalt model like the 55617-TiN. Match the countersink angle (e.g., 120°) to your fastener's head angle. Ensure shank size fits your tool holder.
