Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 6-flute countersink used for?

The KEO 6-flute countersink creates smooth, chatter-free 90° chamfers on holes in metal, plastic, and wood. It is ideal for deburring and countersinking screw heads in industrial machining, tool-and-die work, and fabrication shops where a fine surface finish is required.

What are the specifications of the KEO 919-000-397 countersink?

This KEO countersink has a 90° included angle, 6 flutes, 1 1/2 in body diameter, and 3/4 in shank diameter. It is made of high-speed steel (HSS) for durability in ferrous and non-ferrous materials. The manufacturer part number is 919-000-397.

Where to buy the KEO 919-000-397 countersink worldwide?

3G Electric supplies the KEO 919-000-397 countersink to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time; we source and deliver this HSS countersink globally.

How to select the right KEO countersink for your application?

Choose a KEO countersink based on hole size and material. For 90° chamfers in steel or aluminum, the 6-flute design reduces vibration. Match the body diameter to your chamfer depth and ensure the shank fits your tool holder. Use cutting fluid for longer tool life.
