Frequently Asked Questions

What is the KEO 82° countersink used for?

The KEO 82° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its 4-flute design provides smooth cutting and chip evacuation, making it suitable for production environments where consistent countersink depth and finish are required.

What are the specifications of the KEO 82° countersink?

The KEO countersink has an 82° included angle, 4 flutes, and a 1/2 in body diameter. It is made from cobalt steel for heat resistance and durability. The manufacturer part number is 919-000-529. This tool is designed for use with machine tools such as drill presses and milling machines.

Where to buy the KEO 82° countersink worldwide?

3G Electric supplies the KEO 82° countersink worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time. We source and deliver this tool to support your machining operations.

How to select the correct KEO countersink for your application?

Select the KEO countersink based on the screw head angle and material. The 82° angle matches standard flat-head screws. For harder materials like stainless steel, choose cobalt steel tools for heat resistance. Ensure the body diameter (1/2 in) fits your tool holder and the flute count suits your chip evacuation needs.
