KORLOY TNMG160404HA PC9030 PVD TiAlN Coated 60° Triangular Turning Insert for Stainless Steel Finishing CNC Cutting Tool
KORLOY TNMG160404HA PC9030 60° Triangle Turning Insert
The KORLOY TNMG160404HA PC9030 is a 60° triangular indexable turning insert from KORLOY, engineered for finishing to semi‑finishing turning, boring, and profiling on stainless steel, superalloys, and carbon/alloy steels. It features ultra‑sharp HA chipbreaker, 0.4 mm corner radius, and PC9030 PVD‑coated grade, delivering low cutting force, excellent surface finish, and strong anti‑built‑up edge performance in wet/dry CNC turning. Ideal for precision components in automotive, medical, and general engineering.
- 60° Triangular Shape (TNMG): Negative rake, 3 cutting edges, versatile for external/internal turning.
- Ultra‑Sharp HA Geometry: High positive rake, minimal cutting force, ideal for thin‑wall and long‑overhang parts.
- 0.4 mm Corner Radius (04): Fine finish, reduces stress, suits light depths of cut.
- PC9030 Grade: PVD TiAlN coating, high wear resistance, anti‑chipping, excellent for stainless steel.
- Fine‑Grain Substrate: Balanced toughness and hardness, resists deformation in medium‑low speed cuts.
- Screw‑Clamped: Compatible with standard TNMG toolholders (e.g., MTJNR/L, WTJNR/L).
- Stainless steels (304, 316L, 420) – primary application
- Superalloys (Inconel, Hastelloy, light cuts)
- Carbon steels (1045, S355, finishing)
- Alloy steels (4140, 42CrMo4, HRC <45)
- Cast iron (HT200, semi‑finishing)
- External/internal finishing turning (Ra ≤ 0.8 μm)
- Precision boring and thin‑wall machining
- Profiling and copy turning
- Dry/wet turning of stainless steel
- High‑precision automotive and medical parts
