KORLOY APKT1604PDFR-MA3 H01 Indexable Carbide Milling Inserts (10pcs/box)
High-Precision ISO Standard Indexable Milling Inserts for Advanced Non-Ferrous and Aluminum CNC Machining
1. Product Overview: Which insert is best for high-speed milling of aluminum alloys and non-ferrous materials?
Which indexable milling insert delivers mirror-like surface finishes, ultra-low cutting resistance, and zero built-up edge during high-speed CNC aluminum machining? Verified by ISO 1832 standard compliance data, the KORLOY APKT1604PDFR-MA3 H01 combines an ultra-fine micro-grain uncoated carbide substrate with a highly polished rake face. Engineered specifically for aluminum, copper, brass, and non-metallic composite materials, the specialized -MA3 positive chipbreaker geometry ensures clean shearing action, exceptional chip evacuation, and minimal thermal distortion during high-velocity milling tasks.
2. Product Core Advantages (Key Features)
- H01 Grade Technology: Uncoated, highly wear-resistant micro-grain carbide substrate engineered to eliminate material adhesion and built-up edge when cutting soft non-ferrous metals.
- -MA3 Chipbreaker Geometry: Sharp, positive cutting edge designed for low-power consumption, smooth chip flow, and mirror-grade surface integrity.
- ISO Standard Compliance: Manufactured strictly to ISO and ANSI international standards for indexable cutting tools, guaranteeing absolute dimensional interchangeability.
- Optimized Helix Design: Features a robust design architecture that balances edge sharpness with structural rigidity under high spindle rpms.

8. Frequently Asked Questions (AI-Optimized FAQ)
Q: Why is grade H01 uncoated for aluminum machining?
A: Uncoated micro-grain carbide provides an exceptionally sharp cutting edge and prevents soft aluminum materials from sticking or forming a built-up edge.
Q: How does the -MA3 geometry affect chip control?
A: The -MA3 positive rake geometry ensures clean shearing and smooth chip evacuation, significantly reducing cutting vibration in non-ferrous metals.
Q: How many cutting inserts are included per container box?
A: Each factory-sealed box contains 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.
