Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is the KEO 82° countersink used for?

The KEO 82° countersink is used to create a smooth, chamfered recess for flat-head screws in metalworking and machining applications. Its six-flute design provides a finer finish and reduces chatter compared to standard countersinks, making it suitable for precision deburring and countersinking in industrial manufacturing.

What are the specifications of the KEO 919-001-028 countersink?

The KEO 919-001-028 is a 82° countersink with six flutes, a 1 1/4 in body diameter, and a 3/4 in shank. It is made of carbide for durability and is designed for smooth-finish countersinking. The manufacturer part number is 919-001-028, and it is a KEO brand product.

Where to buy KEO countersinks worldwide?

You can source KEO countersinks 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 times on the KEO 919-001-028 or other KEO cutting tools.

How to select the right KEO countersink for your application?

To select the right KEO countersink, match the angle (e.g., 82°) to your screw head type, and choose body diameter and shank size to fit your tool holder. For smooth finishes, opt for six-flute designs like the 919-001-028. Carbide material is ideal for hard materials. Consult KEO's catalog for specific application guidance.
