TNMG160408 TM HR82512P Huareal Carbide Insert with 60° Triangular Geometry PVD Coated for CNC Turning 9.525mm IC
The HUAREAL TNMG160408-TM HR82512P is a 60° triangular (TN-type) negative rake carbide turning insert, designed for semi-finish to medium turning of carbon steels, alloy steels, and stainless steels. Equipped with a TM general-purpose chipbreaker and HR82512P PVD coated grade, it delivers balanced cutting performance, reliable chip control, and good wear resistance in continuous or light interrupted cuts. Ideal for CNC turning centers and general-purpose lathes, it covers a wide range of common turning applications with stable quality and cost-effectiveness.
- 60° Triangular (TN-type) Geometry: Negative rake, high rigidity, 3 usable cutting edges, reduces tool change frequency.
- TM Chipbreaker (General-purpose): Balanced groove design for medium feeds (0.2–0.4 mm/r); ensures stable chip flow in semi-finish/medium turning.
- HR82512P Grade: PVD (Ti,Al)N coating; excellent wear/oxidation resistance, wide application range for P/M/K materials.
- 0.8mm Corner Radius (R0.8): Optimizes edge strength and surface finish; reduces chipping in light interrupted cuts.
- Negative Rake Design: High edge strength, suitable for heavier cuts and unstable workpieces; compatible with standard TNMG tool holders.
- Versatile Performance: Good balance of toughness and wear resistance; works well in mixed batches and general engineering.
- Carbon steels (1045, S355, Q235)
- Alloy steels (4140, 42CrMo4, HRC <45)
- Stainless steels (304, 316, 420)
- Gray & ductile cast irons
- Pre-hardened steels (HRC ≤45)
- External semi-finish & medium turning
- Internal boring and facing
- Contouring and chamfering
- Automotive, hydraulic, general engineering parts
- Continuous or light interrupted turning
- Medium-volume production
