Carbide vs HSS
The choice between carbide and HSS end mills depends on the application, material, and budget. Each has its own advantages.
Carbide Advantages
- 2-3x higher cutting speeds
- 5-10x longer tool life
- Smoother surface finish
- Can machine hard materials (HRC 50+)
HSS Advantages
- Lower cost per unit
- More resistant to shock/vibration
- Easily re-sharpened
