Frequently Asked Questions

What is the KEO 4-flute countersink used for?

The KEO 90° countersink with four flutes is designed for deburring and chamfering holes in metal workpieces. It creates a clean, countersunk seat for flat-head screws and is commonly used in machining, tool-and-die, and general fabrication applications where precision and surface finish matter.

What are the specifications of the KEO countersink 919-000-547?

This KEO countersink has a 90° included angle, four flutes, and a 1-inch body diameter. It is made from cobalt steel for heat resistance and durability. The manufacturer part number is 919-000-547, and it is designed for use in drill presses, milling machines, or handheld tools.

Where to buy the KEO 919-000-547 countersink worldwide?

3G Electric supplies the KEO 919-000-547 countersink to customers worldwide. As a global industrial 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 any country.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required chamfer angle and material. For standard flat-head screws, a 90° angle is typical. Cobalt steel suits harder materials like stainless steel. Match the body diameter to your hole size and ensure the shank fits your tool holder. Four-flute designs provide smoother cutting and reduced chatter.
