Because of this you’ll find solid carbide used mainly in finishing applications in newer milling machines or those with less spindle wear. This material is more resistant to wear than HSS and prone to chipping instead of wearing out evenly over time.
HSS tools are generally more expensive than others, but they’re built to last and provide a high material removal rate for both ferrous and nonferrous materials. This material combines chromium, tungsten, and molybdenum to give HSS improved hardness, toughness, and wear resistance over carbon steel. You’ll typically find this material used for low-speed operations in twist drills, forming tools, milling cutters, and turning. This is the most inexpensive material of the bunch and includes a total of 0.6-1.5% of carbon with small amounts of manganese and silicon.
The most common materials you’ll encounter in CNC milling tools include: Carbon Steel Before jumping into each tool, let’s focus on what they have in common – tool material and fundamental operation.
