Frequently Asked Questions

What is the KEO 917-000-197 countersink used for?

The KEO 917-000-197 is a 90°, three-flute countersink used to create chamfered holes for screw heads in metalworking. It is designed for general-purpose deburring and countersinking on ferrous and non-ferrous materials, commonly used in machining, fabrication, and maintenance applications.

What are the specifications of the KEO 917-000-197 countersink?

The KEO 917-000-197 is a 90° countersink with three flutes and a 1/4 in body diameter. It is made from cobalt steel for durability in hard materials. The manufacturer part number is 917-000-197, and it is a general-purpose three-flute countersink from KEO.

Where to buy the KEO 917-000-197 countersink worldwide?

3G Electric supplies the KEO 917-000-197 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 on this KEO tool.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle (e.g., 90° for standard screw heads), flute count for chip evacuation, and body diameter matching the hole size. Cobalt steel suits harder materials. For the 917-000-197, ensure your drill press or tool holder accepts a 1/4 in shank.
