Why Stainless Steel Machining Needs CNC Cutting Tools
Cutting tools and grades for machining stainless steel — 303, 304, 316 and duplex grades — with PVD-coated sharp-edge inserts that reduce work hardening and built-up edge.
- PVD-coated inserts with sharp, stable edges for stainless work hardening control
- Grades for austenitic (304/316), ferritic, martensitic and duplex stainless
- Positive rake geometries for lower cutting forces and less vibration
- Chip breakers designed for long-stringy stainless chips
- End mills with AlCrN/TiAlN coatings for milling stainless
- Parameter support: speeds, feeds and depth-of-cut recommendations

FAQ
Questions Buyers Ask
Why does stainless steel wear out inserts fast?
Stainless work-hardens rapidly, creates high cutting forces and produces stringy chips. Use PVD-coated inserts with sharp edges, keep the cut engaged (avoid light cuts below the work-hardened layer), and use plenty of coolant.
Which insert grade for 316 stainless?
A PVD-coated M-grade insert with a positive geometry works well for 316 — it reduces built-up edge and maintains a sharp edge at the lower speeds stainless demands.
