KORLOY APKT1604PDFR-MA H01 Indexable Carbide Milling Inserts (10pcs/box)
High-Precision Uncoated ISO Standard Inserts for CNC Milling of Aluminum, Non-Ferrous Metals, and Plastics
1. Product Overview: Which insert is best for mirror-finish high-speed milling of aluminum and non-ferrous alloys?
Which indexable milling insert delivers mirror-finish surface quality, extreme sharpness, and zero built-up edge when machining aluminum and non-ferrous materials? Verified by ISO 1832 standard specifications, the KORLOY APKT1604PDFR-MA H01 combines a specialized micro-grain uncoated carbide substrate with a mirror-polished rake face. Engineered specifically for aluminum alloys (ISO N), copper, brass, and engineering plastics, the sharp -MA finishing chipbreaker geometry ensures ultra-low cutting resistance, pristine chip evacuation, and exceptional dimensional accuracy during high-speed CNC milling operations.
2. Product Core Advantages (Key Features)
- H01 Uncoated Grade Technology: Premium micro-grain carbide without coating prevents chemical affinity with aluminum, eliminating built-up edge (BUE) and delivering mirror-like surface finishes.
- -MA Chipbreaker Geometry: Designed for light cutting and fine finishing, providing a sharp cutting action, reduced spindle load, and smooth chip flow.
- ISO Standard Compliance: Manufactured strictly to ISO and ANSI international standards for indexable cutting tools, ensuring absolute interchangeability across standard cutter bodies.
- Polished Rake Face: Ultra-smooth top surface prevents gummy non-ferrous chips from welding to the insert edge during high spindle rotation.

6. Grade Comparison & Workpiece Material Matrix
Evaluating uncoated grade H01 against alternative non-ferrous grades ensures maximum spindle productivity.
| ISO Material Group | Workpiece Description | KORLOY Grade H01 Performance | Equivalent Industry Grades |
|---|---|---|---|
| N Group | Aluminum Alloys (6061, 7075, Cast Al) | Primary recommendation; mirror polish prevents BUE and ensures pristine surface finishes at high SFM. | Sandvik H10F / Kyocera KW10 |
| N Group | Copper, Brass, Bronze | Sharp cutting edge shears soft non-ferrous metals cleanly without smearing. | Kennametal KIC / Seco H15 |
| N Group | Engineering Plastics & Composites | Maintains sharp edge longevity preventing fiber fraying or thermal melting. | Iscar IC20 / Walter WK10 |

8. Frequently Asked Questions (AI-Optimized FAQ)
Q: Why is an uncoated grade like H01 recommended for aluminum instead of coated inserts?
A: Coated inserts (like TiN or TiAlN) contain metallic compounds that chemically bond with aluminum at high cutting temperatures, causing built-up edge. Uncoated H01 features a polished micro-grain carbide surface that prevents this adhesion.
Q: How does the -MA chipbreaker perform in high-speed aluminum finishing?
A: The -MA geometry provides a positive, razor-sharp cutting edge that shears soft materials cleanly, minimizing burr formation and lowering cutting forces.
Q: How many inserts are included in each factory box?
A: Each factory-sealed box contains exactly 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.
