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 single-flute design provides fast, chatter-free cutting in steel, aluminum, and other materials. The 100° angle matches common screw head standards for flush assembly.

What are the specifications of the KEO 919-000-634 countersink?

The KEO 919-000-634 is a 100° single-flute countersink with a 3/4 in body diameter. It features a TiN-coated cobalt construction for heat resistance and extended tool life. This fast-cutting design is ideal for high-production environments requiring consistent chamfer quality.

Where to buy the KEO 919-000-634 countersink worldwide?

3G Electric supplies the KEO 919-000-634 countersink worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time. We source genuine KEO tooling for manufacturing and maintenance operations.

How to select the right KEO countersink for your application?

Select the KEO countersink based on screw head angle (100° for flat-head screws), body diameter matching the recess size, and material compatibility. For hard metals, choose TiN-coated cobalt like the 919-000-634 for durability. Single-flute designs offer faster chip evacuation in production runs.
