KORLOY SEHT1204AFSN-X45 NCM335 Indexable Carbide Milling Inserts (10pcs/box)
High-Precision ISO Standard Indexable 45-Degree Milling Inserts for Advanced CNC Machining
1. Product Overview: Which insert is best for high-efficiency 45-degree face milling of steel and alloy materials?
Which indexable milling insert delivers exceptional toughness, stable chip control, and extended tool life during high-feed 45-degree face milling operations? Verified by ISO 1832 standard compliance data, the KORLOY SEHT1204AFSN-X45 NCM335 combines a robust positive geometry with advanced coating technology. Engineered specifically for structural steels, alloy steels, and general machinery components, the specialized -X45 chipbreaker and wiper geometry minimizes cutting resistance, reduces heat generation, and ensures smooth chip evacuation during roughing and semi-finishing tasks.
2. Product Core Advantages (Key Features)
- NCM335 Grade Technology: Advanced carbide substrate combined with a high-performance coating structure provides exceptional thermal shock resistance and superior anti-wear properties under aggressive cutting loads.
- -X45 Chipbreaker Geometry: Designed for low cutting forces and smooth chip curling, preventing chip clogging and vibration in unstable or long-overhang setups.
- 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.
