Frequently Asked Questions

What is the KEO 60° countersink used for?

The KEO 60° countersink is used to create a conical recess for flathead screws or deburr holes in metalworking. It is ideal for machining centers, drill presses, and manual operations where a precise 60° chamfer is required on ferrous and non-ferrous materials.

What are the specifications of the KEO 919-000-131 countersink?

The KEO 919-000-131 is a 60° single-flute countersink with a 1 1/2 in body diameter and a 3/4 in shank. It is made of high-speed steel (HSS) for durability. The single-flute design enables fast cutting and chip evacuation in production environments.

Where to buy the KEO 60° countersink worldwide?

3G Electric supplies the KEO 60° 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 and deliver this KEO tool to any international destination.

How to select the correct KEO countersink size?

Select the KEO countersink based on the screw head diameter and desired chamfer angle. For flathead screws, match the countersink angle (60°) to the screw's head angle. Ensure the body diameter exceeds the screw head, and the shank fits your tool holder. KEO offers HSS for general use.
