Frequently Asked Questions

What is a KEO 60° countersink used for?

A KEO 60° countersink is used to create a conical recess in metal or plastic for flush-mounting flat-head screws. It is common in aerospace, automotive, and general machining where precise chamfering or deburring of holes is required.

What are the specifications of the KEO 917-000-140 countersink?

The KEO 917-000-140 is a 60° four-flute countersink with a 2-inch body diameter and a 3/4-inch shank. It is made of TiN-coated high-speed steel for wear resistance. The four-flute design reduces chatter and provides a smooth finish.

How to select the right KEO countersink for my application?

Select a KEO countersink based on the required angle (e.g., 60° for standard flat-head screws), material hardness (TiN-coated HSS for steel), and shank size to match your tool holder. For large holes, choose a body diameter that exceeds the screw head size.
