Frequently Asked Questions

What is a CLEVELAND 120° countersink used for?

A CLEVELAND 120° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications.

What are the specifications of the CLEVELAND C46129 countersink?

The CLEVELAND C46129 is a 120° countersink with 1 flute and a 3/4 in body diameter. It is made from black oxide high-speed steel for heat resistance and reduced friction. This single-flute design is optimized for fast cutting and clean finishes in production environments.

How to select the right CLEVELAND countersink for your application?
