Frequently Asked Questions

What is the KEO 120° countersink used for?

The KEO 120° countersink is used for deburring and countersinking holes in metal, plastic, and wood. Its 120-degree angle is ideal for creating a chamfer for flat-head screws or preparing holes for welding. The three-flute design provides smooth, chatter-free operation in general-purpose industrial applications.

What are the specifications of the KEO 917-000-257 countersink?

The KEO 917-000-257 is a 120° 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 917-000-257, and it is designed for general-purpose deburring and countersinking tasks.

Where to buy the KEO countersink 917-000-257 worldwide?

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle and material. For flat-head screws, use a 120° angle. Match the body diameter to your drill chuck capacity. Cobalt steel is best for hard metals; high-speed steel suits softer materials. Ensure the flute count matches your need for chip evacuation and finish.
