Product Description

KEO Four-Flute Machine Countersinks.

Frequently Asked Questions

What is the KEO 82° countersink used for?

The KEO 82° countersink is used to create a conical recess in metal or plastic for flat-head screws. Its 4-flute design provides smooth cutting and chip clearance, ideal for deburring and countersinking in machining and fabrication applications.

What are the specifications of the KEO 919-000-533 countersink?

The KEO 919-000-533 is an 82°, 4-flute machine countersink with a 3/4 in body diameter, made from cobalt steel. It is designed for use in drill presses or CNC machines to produce precise countersinks in ferrous and non-ferrous materials.

Where to buy the KEO 82° countersink worldwide?

You can source the KEO 82° countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring reliable supply for your machining needs.

How to select the correct KEO countersink size?

Select the KEO countersink based on the screw head angle and body diameter. For flat-head screws, match the 82° angle and choose a body diameter slightly larger than the screw head. The 3/4 in body suits medium-sized fasteners in general machining.
