Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink creates a conical recess for flat-head screws in metalworking. This zero-flute design reduces vibration and chatter, producing a smoother finish in hardened steels and alloys. It is commonly used in aerospace, automotive, and general machining applications.

What are the specifications of the KEO 919-000-236 countersink?

The KEO 919-000-236 is a 100° countersink with a 5/16 in body diameter, zero flutes, and made from cobalt steel. It is designed for anti-vibration performance in high-hardness materials. The manufacturer part number is 919-000-236, and it is produced by KEO.

Where to buy KEO countersinks worldwide?

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 100° for flat-head screws), material hardness (cobalt for tough alloys), and body diameter matching the screw size. Zero-flute designs minimize chatter in CNC or manual operations. Always verify the shank compatibility with your toolholder.
