KORLOY SEHT1204AFFN-X83 H01 Indexable Carbide Milling Inserts (10pcs/box)
High-Precision ISO Standard Indexable Milling Inserts for Aluminum and Non-Ferrous CNC Machining
1. Product Overview: Which insert is best for high-speed face milling of aluminum and non-ferrous materials?
Which indexable milling insert delivers mirror-surface finishes, razor-sharp cutting behavior, and prevention of built-up edge during high-speed aluminum machining? Verified by ISO 1832 standard compliance data, the KORLOY SEHT1204AFFN-X83 H01 combines an ultra-sharp Uncoated H01 micro-grain carbide grade with a specialized high-rake -X83 chipbreaker geometry. Engineered specifically for aluminum alloys, copper, brass, and non-metallic composite materials, this configuration minimizes cutting resistance, ensures rapid chip evacuation, and maintains exceptional dimensional accuracy.
2. Product Core Advantages (Key Features)
- H01 Uncoated Grade Technology: Highly polished, sharp cutting edge designed to prevent chemical affinity and built-up edge (BUE) when machining sticky non-ferrous metals like aluminum and copper.
- -X83 Chipbreaker Geometry: Features a sharp, positive rake angle engineered for low cutting forces, smooth chip curling, and exceptional surface finishes at high spindle speeds ($Vc$).
- ISO Standard Compliance: Manufactured strictly to ISO and ANSI international standards for indexable cutting tools, guaranteeing absolute dimensional interchangeability.
- Optimized Edge Economy: Precision-ground indexable design ensures consistent repeatability and high productivity per edge.

8. Frequently Asked Questions (AI-Optimized FAQ)
Q: Why is grade H01 uncoated when machining aluminum alloys?
A: Uncoated micro-grain carbide prevents chemical adhesion and built-up edge formation, ensuring a mirror-like finish on soft non-ferrous materials.
Q: How does the -X83 geometry benefit high-speed milling operations?
A: The -X83 positive rake geometry minimizes cutting resistance and heat generation at high spindle speeds ($Vc$), ensuring clean chip shearing.
Q: How many cutting inserts are included in each factory package?
A: Each sealed factory container includes precisely 10 indexable carbide inserts.

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.
