Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 82° 6-flute countersink used for?

The KEO 82° 6-flute countersink is used for deburring and countersinking holes in metal, creating a smooth, chamfered seat for flat-head screws. Its six-flute design reduces chatter and vibration, making it ideal for precision work in machining, automotive, and aerospace applications.

What are the specifications of the KEO 82° countersink?

The KEO countersink has an 82° included angle, 6 flutes, and a 3/8 in body diameter. It is made from cobalt steel (MPN 919-000-737) for durability in hard materials. The smooth-finish design ensures clean, burr-free holes in metalworking tasks.

Where to buy the KEO 82° countersink worldwide?

You can source the KEO 82° 6-flute countersink worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this cobalt countersink.

How to select the right KEO countersink for metalworking?

Select a KEO countersink based on hole angle (82° for flat-head screws), flute count (6 flutes for smoother finish), and material compatibility. Cobalt steel suits harder metals like stainless steel. Match body diameter to your drill size and ensure the shank fits your tool holder.
