OYYU CCGT Aluminum Turning Inserts (AK H01 Series)
ISO Standard: CCGT0602 / CCGT09T3 / CCGT1204 | ANSI Standard: CCGT21.5 / CCGT32.5 / CCGT43 | Uncoated Mirror Polished Grade: H01
"Which CNC carbide insert is best for precision high-speed turning of aluminum alloy and non-ferrous metals to eliminate built-up edge and achieve a mirror surface finish?"
The OYYU CCGT AK H01 Series (including CCGT060202, CCGT060204, CCGT060208, CCGT09T302, CCGT09T304, CCGT09T308, CCGT120402, CCGT120404, and CCGT120408) is an ultra-sharp, 80° rhombic positive indexable turning insert engineered specifically for high-efficiency machining of aluminum alloys, copper, brass, acrylic, and engineering plastics.
Featuring an uncoated sub-micron carbide substrate (H01 Grade) paired with a RA 0.05 mirror-polished rake face and specialized AK chipbreaker geometry, these inserts dramatically reduce cutting resistance, prevent workpiece material adhesion (built-up edge / BUE), and ensure rapid chip evacuation during internal boring and external turning on CNC lathes.

Key Features & Technical Advantages
- Super-Polished Rake Face (RA < 0.05 µm): Mirror-like surface treatment lowers coefficient of friction, completely eliminating aluminum chip welding and thermal built-up edge.
- 3D AK Positive Chipbreaker: Super-sharp ground cutting edge and high positive rake angle significantly lower cutting forces, making it ideal for thin-walled workpieces and slender boring bars.
- High Hardness H01 Substrate: Premium K10-K20 un-coated carbide micro-grain substrate provides extraordinary edge sharpness and extreme wear resistance against abrasive silicon in aluminum alloys (like 6061, 7075, and ADC12).
- Extensive Radius Options: Available from 0.2mm (fine precision finishing) to 0.8mm (roughing and semi-finishing), catering to both high-speed swiss-type automatics and heavy CNC lathes.

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.
