Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its three-flute design provides smooth cutting and reduced chatter, making it suitable for general-purpose deburring and countersinking on ferrous and non-ferrous materials.

What are the specifications of the KEO countersink 917-000-365?

The KEO countersink model 917-000-365 has a 100° included angle, three flutes, and a 1/4 in body diameter. It is made from carbide for durability and precision. This general-purpose tool is designed for use with manual or CNC machines to produce clean, accurate countersinks.

Where to buy the KEO 100° countersink worldwide?

You can source the KEO 100° countersink 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 time; we supply genuine KEO tooling for machining operations.

How to select the right KEO countersink for your application?

Select the KEO countersink based on the screw head angle—100° for metric flat-head screws—and material. Carbide tools suit harder metals and offer longer life. Match the body diameter to your workpiece and toolholder. For best results, use proper cutting speeds and lubrication as recommended for carbide tooling.
