Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink with three flutes is used to create a conical recess for flat-head screws in metalworking and machining. The 100° angle is common in aerospace and sheet-metal applications. KEO's TiN-coated carbide construction provides wear resistance for extended tool life in production environments.

What are the specifications of the KEO 917-001-022 countersink?

The KEO 917-001-022 is a general-purpose three-flute countersink with a 1 1/4 in body diameter and a 3/4 in shank. It features a 100° included angle and is made from TiN-coated carbide. This combination suits high-speed steel or CNC applications requiring precise chamfering on ferrous and non-ferrous materials.

Where to buy KEO countersinks worldwide?

Contact us for a quote on this TiN-coated carbide three-flute countersink with a 1 1/4 in body diameter and 3/4 in shank.

How to select the right countersink for a machining job?

Select a countersink based on the screw head angle (e.g., 100° for aerospace), material hardness (carbide for steel, HSS for aluminum), and flute count (three flutes reduce chatter). KEO's TiN-coated carbide option provides heat resistance for longer runs. Match shank diameter to your collet or chuck size for secure holding.
