KEO Four-Flute Machine Countersinks.

Frequently Asked Questions

What is the KEO 60° countersink used for?

The KEO 60° countersink is used for deburring and countersinking holes in metal, creating a conical seat for flat-head screws. It is common in machining and fabrication, especially on steel and aluminum, where a 60° included angle is required for precision chamfering.

What are the specifications of the KEO 60° countersink?

The KEO 60° countersink has a 7/8 in body diameter, 4 flutes, and is made from cobalt steel. The manufacturer part number is 919-000-525. It is a four-flute machine countersink designed for use in drill presses or CNC machines, providing smooth cutting action.

Where to buy the KEO 60° countersink worldwide?

You can source the KEO 60° countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this KEO part.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required angle (60° for standard flat-head screws), body diameter matching the hole size, and material compatibility. Cobalt steel suits harder metals. For precision, match flute count to material type—4 flutes provide balanced cutting on steel and aluminum.
