Korloy TCGT090204-AK H01 Polished Insert for Aluminum & Non-Ferrous Turning (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy TCGT090204-AK H01 is a high-performance Triangular Turning Insert designed for the precision machining of Aluminum, Copper, Brass, and Plastics. The H01 Grade features an uncoated, ultra-fine micro-grain carbide substrate with a Mirror-Polished Top Face. Combined with the legendary AK Chipbreaker, this insert provides an ultra-sharp cutting edge that prevents chip welding and delivers a superior mirror-like surface finish.
Superior Versatility: The 0.4mm (R0.4) corner radius provides the perfect balance between edge strength and surface finish. It is robust enough for light roughing while still sharp enough to achieve high-gloss finishes on aerospace-grade aluminum.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Designation | TCGT090204-AK |
| Corner Radius (r) | 0.4 mm (Industry Standard) |
| Grade | H01 (Uncoated Mirror-Polished Carbide) |
| Application | Aluminum, Copper, Brass, Delrin, Wood |
Core Performance Benefits:
- Extreme Sharpness: The "AK" geometry is ground to a razor edge, significantly reducing cutting forces and heat buildup.
- Chip Evacuation: The mirror-polished rake face allows chips to slide effortlessly, eliminating Built-Up Edge (BUE) even in gummy aluminum alloys.
- Durable R0.4 Edge: Compared to R0.2, this version offers better resistance to edge chipping, allowing for faster feed rates and longer tool life.
- Mirror Surface Quality: Achieves exceptional Ra values, reducing or eliminating the need for post-machining polishing.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum (6061/7075) | 300 - 1000 m/min | 0.10 - 0.25 mm/rev | 0.1 - 3.0 mm |
| Brass / Bronze | 150 - 600 m/min | 0.08 - 0.20 mm/rev | 0.1 - 2.0 mm |
| Hard Wood / Acrylic | 200 - 500 m/min | 0.10 - 0.30 mm/rev | 0.2 - 4.0 mm |
Compatible Tooling Holders:
Fits all standard 09-sized triangular toolholders:
- External Turning: STGCR 1616H09 / STGCR 2020K09
- Internal Boring: S10K-STFCR09 / S12M-STFCR09
Machinist Tip: R0.4 vs R0.2 in Aluminum Turning
Choosing between the TCGT090204 and TCGT090202:
The Efficiency King. The 0.4mm radius allows for higher feed rates while maintaining an excellent finish. It is the best choice for general purpose aluminum turning and parts with higher vibration risks.
The Precision Detailer. Use the 0.2mm radius for very small diameters, thin-walled components, or when an extremely small corner radius is required by the part drawing.
Pro Advice: To achieve a true "Mirror Finish," use a high cutting speed (Vc > 500m/min) and ensure your coolant is directed exactly at the tool-workpiece interface to flush chips instantly.
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.
