Korloy TCGT110202-AK H01 Mirror Polished Insert for Precision Aluminum (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy TCGT110202-AK H01 is a professional-grade Triangular Indexable Insert designed for the ultra-precision turning of Aluminum, Copper, and Non-Ferrous Metals. Featuring the H01 Uncoated Carbide Grade, each insert undergoes a specialized Mirror-Polishing process on the rake face. Combined with the razor-sharp AK chipbreaker, it delivers a flawless surface finish and maintains tight tolerances even on the most delicate workpieces.
The Thin-Wall Specialist: The 0.2mm (R0.2) corner radius minimizes radial cutting forces. This makes the TCGT110202 indispensable for thin-walled aluminum tubes or small diameter components where vibration and part deflection must be avoided.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Designation | TCGT110202-AK |
| Corner Radius (r) | 0.2 mm (Ultra-Precision) |
| Grade | H01 (Micro-grain Polished Carbide) |
| Insert Thickness | 2.38 mm |
Core Performance Benefits:
- Anti-Stick Performance: The mirror-like surface prevents "chip welding" (BUE), a common issue when machining soft 1000 or 6000 series aluminum.
- Superior Sharpness: Ground to a micro-level edge to ensure clean shearing of the material, resulting in high-gloss finishes.
- Versatile Non-Ferrous Tooling: While optimized for aluminum, it performs exceptionally well on Copper, Brass, Gold, and Plastics.
- G-Class Precision: Higher manufacturing tolerance than standard M-class inserts, ensuring repeatability in CNC mass production.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum Alloys | 300 - 900 m/min | 0.03 - 0.12 mm/rev | 0.05 - 1.5 mm |
| Oxygen-Free Copper | 150 - 450 m/min | 0.03 - 0.10 mm/rev | 0.05 - 1.0 mm |
| Acrylic / PMMA | 100 - 400 m/min | 0.05 - 0.20 mm/rev | 0.10 - 2.0 mm |
Compatible Tooling Holders:
For best results, use with high-precision boring bars and toolholders:
- Boring Bars (Internal): S12M-STFCR11 / S16Q-STFCR11
- Turning Holders (External): STGCR 1212H11 / STGCR 1616H11
Machinist Tip: Why R0.2 over R0.4?
Selecting the best radius for non-ferrous machining:
Best for Precision. Use this when you need extremely sharp corners or when your machine setup is prone to vibration. The smaller radius cuts through material like a razor with almost zero pushing force.
Best for Efficiency. If your workpiece is stable and you want to increase feed rates (productivity) while still getting a great finish, the 0.4 radius is the stronger choice.
Pro Advice: Always use high-pressure coolant or a strong air blast to ensure chips are cleared instantly. Re-cutting an aluminum chip will ruin the mirror finish provided by the H01 grade.
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.
