Key Features & Benefits
- ISO TPMR160308 designation — Standard 60° triangle, 16mm inscribed circle, 3.18mm thick, 0.8mm corner radius — fits any TPMR-pocket holder.
- Top-clamp retention — TPMR has no centre hole — uses a top clamp on the holder for rigid support against cutting forces.
- Positive rake geometry — Easier on the spindle than negative-rake inserts; suits lighter lathes and softer materials.
- TiAlN coating — Hard violet-gold coating resists wear and crater formation at higher cutting temperatures.
- Three indexable corners — Three usable cutting tips per insert means 30 working corners in a pack of ten.
When to Use This Insert
Choose TPMR160308 for general-purpose semi-finishing turning in steel, stainless and cast iron when your holder accepts top-clamp triangle inserts. Stick to moderate depths (0.5-3mm) — TPMR is not a heavy roughing geometry.
