The Original Korloy TCGT16T302-AK H01 is a premium Large-Scale Triangular Turning Insert specifically engineered for high-precision finishing of Aluminum, Copper, and Non-Ferrous Metals. Featuring a substantial 16mm cutting edge and the ultra-fine H01 Grade, this insert undergoes a professional Mirror-Polishing process. The combination of the sharp AK chipbreaker and the delicate 0.2mm radius makes it the ultimate tool for achieving high-gloss surfaces on large workpieces and in challenging deep-boring scenarios.
The Anti-Vibration Specialist: In deep hole boring or when using long-reach toolholders, vibration is your biggest enemy. The 0.2mm (R0.2) corner radius of the TCGT16T302 minimizes radial cutting force, effectively suppressing "chatter" and ensuring a stable, mirror-like finish even at high L/D ratios.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Designation | TCGT16T302-AK |
| Corner Radius (r) | 0.2 mm (Ultra-Precision) |
| Insert Thickness | 3.97 mm |

Core Performance Benefits:
- Flawless Chip Flow: The mirror-polished rake face prevents "Built-Up Edge" (BUE), allowing chips to slide away instantly—critical for maintaining surface integrity on expensive aluminum components.
- Reduced Tool Pressure: Ground to a razor-sharp edge, this insert shears through soft metals with minimal force, preventing deformation of thin-walled parts.
- Large Scale Capability: The 16mm edge length allows for greater depth of cut flexibility compared to smaller 09 or 11 sizes.
- Optical Grade Finish: Perfect for aerospace, automotive, and optical industries where Ra values are strictly monitored.
Recommended Cutting Parameters:

Machinist Tip: Scaling Up Your Finish
Why TCGT16T302 H01 is the "Secret Weapon" for large bores:
The Mirror King. While DLC coatings are hard, they add thickness to the edge. H01 remains thinner and sharper, which is why it is preferred for the ultimate "jewelry-like" finish on non-ferrous metals.
Precision over Production. In a large 16mm insert, the R0.2 corner is delicate. Use it when you have stability issues. If your machine is rigid and you need to move faster, switch to the R0.4 (16T304) version.
Pro Advice: For deep boring in aluminum, always use through-tool coolant. This clears chips from the hole immediately, preventing them from being re-cut, which is the #1 cause of surface scratches.
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.
