KORLOY SECA1204AFTN PC3500 Indexable Carbide Milling Inserts (10pcs/box)
High-Precision ISO Standard Indexable Milling Inserts for Advanced CNC Steel and Cast Iron Machining
1. Product Overview: Which insert is best for high-reliability face milling and roughing of steel and cast iron?
Which indexable milling insert delivers outstanding thermal shock resistance, heavy-duty fracture toughness, and reliable tool life during demanding CNC milling operations? Verified by ISO 1832 standard compliance data, the KORLOY SECA1204AFTN PC3500 combines a tough carbide substrate with a robust multi-layer CVD coating. Engineered specifically for carbon steels, alloy steels, and gray or ductile cast irons, the specialized -AFTN geometry and positive cutting action minimize cutting resistance, suppress vibration, and ensure stable performance during heavy roughing and general face milling.
2. Product Core Advantages (Key Features)
- PC3500 Grade Technology: Advanced CVD coating combined with a tough carbide substrate provides superior resistance to thermal cracking and chipping under interrupted cutting loads.
- -AFTN Chipbreaker Geometry: Designed for smooth chip formation, low cutting forces, and exceptional edge strength during high metal removal rate (MRR) operations.
- ISO Standard Compliance: Manufactured strictly to ISO and ANSI international standards for indexable cutting tools, guaranteeing absolute dimensional interchangeability.
- Dual-Sided Economy: Indexable dual-sided design maximizes total edge utilization and lowers overall component production costs.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
