What Is An End Mill? A Complete Beginner's Guide
Before choosing an end mill, you need to consider certain factors explained in this section. 1. End mill coatings – Coated end mills are most likely to last longer because the coat stands as the protective layer between end mills and workpieces. It limits the direct impact on end mills, giving the former wear resistance.
