Frequently Asked Questions

What is the KEO 82° countersink used for?

The KEO 82° single-flute countersink is designed for deburring and countersinking holes in metal, particularly steel and stainless steel. Its 82° angle matches standard flat-head screw angles, making it ideal for aerospace, automotive, and general fabrication where a smooth, chamfered hole is required.

What are the specifications of the KEO 919-000-591 countersink?

This KEO countersink has an 82° included angle, 1 flute, 1 1/2 in body diameter, and a 3/4 in shank. It is made from cobalt steel (MPN 919-000-591) for heat resistance and durability. The single-flute design provides fast, chatter-free cutting in hard materials.

Where to buy the KEO 82° countersink worldwide?

3G Electric supplies the KEO 82° countersink (MPN 919-000-591) to global buyers. As an industrial distributor, we handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we source and deliver this KEO tool to your facility.

How to select the right KEO countersink for my application?

Choose the KEO 82° countersink for standard flat-head screws in steel or stainless steel. Match the body diameter to your hole size and shank to your tool holder. For harder materials, the cobalt construction offers heat resistance. Ensure your RPM and feed rate suit single-flute tools to avoid chatter.
