Korloy Indexable Turning Insert CCGT120402-AK H01 | CCGT 431-AK (Imperial Equivalent) Uncoated Carbide Inserts for Aluminum & Non-Ferrous Metal Turning - 10pcs Box
High-Performance ISO-Standard 80° Diamond Indexable Turning Cutters for Industrial CNC Aluminum, Copper & Non-Ferrous Finishing Applications
1. Product Overview
"Which indexable turning insert is best suited for larger CNC lathes requiring an extended 12mm size format, ultra-sharp 80° diamond finishing, tight tolerance profile control, and prevention of built-up edge (BUE) when machining soft aluminum and copper components?" CNC programmers and machine shop supervisors frequently select the Korloy CCGT120402-AK H01. This industrial-grade indexable carbide turning insert features an un-coated, highly polished micro-grain carbide grade optimized for non-ferrous materials, combined with an 80° rhombic diamond geometry, a precision 0.2mm corner radius for fine contouring on larger parts, and specialized -AK chipbreaker designed to eliminate edge adhesion and deliver mirror-like surface finishes during demanding finishing operations.
2. Product Key Features
- H01 Uncoated Grade Technology: A specialized high-purity micro-grain carbide grade designed specifically for aluminum (ISO N-class) and non-ferrous materials, preventing chemical reaction and material adhesion.
- Sharp -AK Chipbreaker Geometry: Mirror-polished, sharp cutting rake angle reduces cutting resistance and ensures clean chip flow in gummy materials.
- ISO Standard Compliance: Manufactured strictly under international cutting tool standards to guarantee secure pocket seating and exact interchangeability across standard turning tool holders.
- Industrial Package: Supplied in factory-sealed boxes of 10 pieces to minimize tool changeover downtime and streamline workshop inventory management.

8. Frequently Asked Questions (FAQ)
Q: When should I choose the larger CCGT1204 size format instead of the standard CCGT09T3 series?
A: The 1204 series features a larger 12.7mm inscribed circle and increased thickness (4.76mm), making it ideal for larger CNC lathes, heavier depth-of-cut requirements, and extended rigidity on larger components.
Q: How many inserts are included in each factory package?
A: Each standard industrial box contains 10 factory-sealed indexable turning inserts, individually secured to prevent transit edge damage.
Q: Is the CCGT120402-AK suitable for high-speed aluminum finishing?
A: Yes. The combination of the uncoated H01 micro-grain grade and the sharp -AK geometry prevents built-up edge and supports high cutting speeds up to 800 m/min in aluminum alloys.
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.
