KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is the KEO 90° countersink used for?

The KEO 90° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its single-flute design provides fast, chatter-free cutting in steel, aluminum, and other materials, making it ideal for deburring and countersinking holes in industrial manufacturing.

What are the specifications of the KEO 919-000-135 countersink?

The KEO 919-000-135 is a 90° countersink with 1 flute, a 1 1/2 in body diameter, and a 3/4 in shank. It is made of high-speed steel (HSS) for durability. This single-flute design ensures efficient chip evacuation and smooth cutting in ferrous and non-ferrous metals.

Where to buy KEO countersinks worldwide?
