TNMGCarbide Turning Inserts

APPLICATION REVIEW

Typical uses to discuss

• Turning and facing where a triangular insert and holder suit the part
• Application-specific roughing or finishing after geometry and grade review

These are general application contexts, not a performance guarantee or a recommendation for an unverified insert.

Workpiece materials

For steel, stainless steel or cast iron, share the exact material grade and hardness. The family code alone does not establish material suitability.
