For example, steel end mills are more rigid than their carbide counterparts. Moreover, HSS endmills are less expensive and less brittle. However, if you're looking for greater productivity and fewer tooling changes, carbide endmills are the best choice. While carbide is more expensive, it's also more durable, longer lasting, and easier to use.
