Korloy TCGT110204-AK H01 Mirror Polished Turning Insert for Aluminum (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy TCGT110204-AK H01 is a high-performance Triangular Indexable Insert engineered for the precision turning of Aluminum, Copper, Brass, and Non-Ferrous alloys. Featuring the elite H01 Uncoated Carbide Grade, this insert is distinguished by its Mirror-Polished surface and razor-sharp AK chipbreaker. It is designed to maximize productivity by allowing higher feed rates while maintaining a flawless, high-gloss surface finish.
The Performance Standard: The 0.4mm (R0.4) radius is the most popular choice for general aluminum machining. It provides significantly better resistance to edge chipping than the R0.2 version, making it ideal for both high-speed finishing and light semi-finishing operations.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Designation | TCGT110204-AK |
| Corner Radius (r) | 0.4 mm (Industry Standard) |
| Grade | H01 (Micro-grain Mirror-Polished Carbide) |
| Materials | Aluminum, Copper, Plastics, Brass |
Core Performance Benefits:
- Anti-Adhesion Surface: The mirror-polished rake face eliminates chip welding (Built-Up Edge), ensuring consistent tool life and surface integrity.
- Enhanced Edge Strength: The R0.4 radius allows for deeper cuts and faster feeds compared to precision finishing R0.2 inserts.
- Ultra-Sharp Geometry: The AK chipbreaker is ground to a fine edge to shear material cleanly, reducing burr formation on soft metals.
- Superior Versatility: Excellent for a wide range of non-ferrous materials, including plastics like POM, Nylon, and Acrylic.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum (6061 / 7075) | 350 - 1000 m/min | 0.10 - 0.25 mm/rev | 0.1 - 2.5 mm |
| Yellow Brass / Bronze | 150 - 550 m/min | 0.08 - 0.20 mm/rev | 0.1 - 1.8 mm |
| Copper (T1 / T2) | 120 - 450 m/min | 0.05 - 0.15 mm/rev | 0.1 - 1.5 mm |
Compatible Tooling Systems:
Optimized for 11-size triangular holders and boring bars:
- Internal Boring Bars: S12M-STFCR11 / S16Q-STFCR11
- External Toolholders: STGCR 1616H11 / STGCR 2020K11
Machinist Tip: Maximizing Surface Gloss
Why choosing the R0.4 H01 grade is the key to productivity:
The Finishing Champion. Perfect for general aluminum alloys. The mirror polish ensures chips slide off instantly. For the brightest shine, use the highest possible Vc (Speed) and ensure your coolant is clean.
The Abrasive Specialist. If you are machining high-silicon cast aluminum (like engine parts), upgrade to DLC coating to prevent the micro-grains in the aluminum from wearing down your sharp edge.
Pro Advice: TCGT110204 is the "safe" choice. If your part has complex geometry or is very small, switch to the 110202 (R0.2) to reduce cutting pressure and prevent thin walls from bending.
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.
