Frequently Asked Questions

What is an OSG double-end carbide square end mill used for?

An OSG double-end carbide square end mill is used for precision milling of slots, shoulders, and contours in metalworking. Its square end creates 90° corners, and the double-end design provides two cutting sections per tool, extending tool life in production machining.
