A step up from HSS with better heat resistance. Ideal for tougher metals like stainless steel.
Choosing the right end mill isn't just about finding a sharp bit; it's about matching tool geometry and material to your specific project. Using the wrong tool can lead to poor surface finishes, excessive tool wear, or even total tool failure. 1. Match the Tool Material to Your Workpiece
The industry standard for high-performance milling. It is extremely hard and allows for much higher speeds and feeds on steel and cast iron, though it is more brittle than HSS. 2. Choose Your Tip Geometry
Affordable and tough against shock, but wears out quickly. Best for wood, plastics, and soft metals like aluminum.
The substrate of your end mill determines its durability and heat resistance.
