The Original Korloy TCGT090202-AK H01 is a premium Triangular Indexable Insert specifically designed for high-performance machining of Aluminum, Copper, and Non-Ferrous Metals. The H01 Grade features an uncoated, ultra-fine micro-grain carbide substrate with a Mirror-Polished surface. This "Mirror Finish" technology, combined with the ultra-sharp AK Chipbreaker, eliminates material adhesion (Built-Up Edge) and delivers an exceptional surface quality that often eliminates the need for secondary polishing.
The Precision Choice: With a 0.2mm (R0.2) corner radius, this insert is optimized for High-Precision Finishing and intricate detailing. Its razor-sharp cutting edge ensures minimal cutting force, preventing thin-walled parts from deforming during the machining process.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Designation | TCGT090202L-AK / TCGT090202R-AK |
| Corner Radius (r) | 0.2 mm (Ultra-Fine Finish) |
| Grade | H01 (Uncoated Mirror-Polished Carbide) |
| Applicable Materials | Aluminum, Copper, Brass, Plastic, Wood |
Core Performance Benefits:
- Mirror-Polished Top Face: Drastically reduces friction, allowing chips to flow smoothly away from the workpiece without sticking.
- Razor Sharp "AK" Geometry: Engineered for low cutting resistance, providing clean cuts and avoiding "burr" formation on soft metals.
- High Dimensional Accuracy: The G-class tolerance (TCGT) ensures consistent precision across every insert in the box.
- Micro-Grain Substrate: Provides the necessary hardness to maintain a sharp edge even when machining abrasive high-silicon aluminum alloys.
Recommended Cutting Parameters:
| Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloy | 200 - 800 m/min | 0.05 - 0.15 mm/rev | 0.1 - 2.0 mm |
| Copper / Brass | 150 - 500 m/min | 0.05 - 0.12 mm/rev | 0.1 - 1.5 mm |
| Plastics (Delrin/PVC) | 100 - 400 m/min | 0.10 - 0.25 mm/rev | 0.2 - 3.0 mm |
Compatible Turning Toolholders:
Pairs perfectly with internal boring bars and external turning tools:
- Internal Boring Bars: S08K-STFCR09 / S10K-STFCR09
- External Turning Tools: STGCR 1212H09 / STGCR 1616H09
Tech Tip: Aluminum Grade Comparison
Selecting the right grade for your non-ferrous project:
The Mirror King. Best for pure aluminum and low-silicon alloys. Provides the lowest friction and the brightest surface finish. 100% immune to "chip welding."
The Abrasive Expert. For high-silicon aluminum (Cast Aluminum like ADC12), DLC coating provides extra hardness to resist tool wear while keeping the surface smooth.
Pro Advice: TCGT090202 (R0.2) is extremely sharp but delicate. If your application involves heavy roughing or interrupted cuts, consider stepping up to the TCGT090204 (R0.4) for more edge strength.
Packaging: 10 pieces per box.

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.
