The Original Korloy TCGT16T308-AK H01 is a robust Large Triangular Indexable Insert designed for high-efficiency machining of Aluminum, Copper, Brass, and Non-Ferrous Alloys. Featuring a 16mm edge and a reinforced 0.8mm corner radius, this insert is the go-to choice for heavy material removal and high-feed applications. The H01 Grade micro-grain carbide is Mirror-Polished to a high gloss, ensuring maximum chip flow and a superior surface finish even during aggressive cutting cycles.
Maximum Edge Strength: The 0.8mm (R0.8) radius makes this the "Heavyweight" of the TCGT series. It is specifically engineered to handle interrupted cuts or large depths of cut in aluminum forgings and castings where smaller radii might chip or fail.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Designation | TCGT16T308-AK |
| Corner Radius (r) | 0.8 mm (Heavy Duty) |
| Grade | H01 (Micro-grain Mirror-Polished Carbide) |
| Insert Side Length | 16.5 mm |
Core Performance Benefits:
- High-Feed Capability: The large R0.8 radius allows for aggressive feed rates, significantly reducing cycle times in large-scale aluminum production.
- Aggressive Chip Breaking: The AK geometry combined with the larger radius facilitates controlled chip breaking even at higher depths of cut (ap).
- Anti-Welding Technology: The mirror-polished rake face prevents "Built-Up Edge" (BUE), a critical factor when running at high speeds in gummy non-ferrous metals.
- Exceptional Durability: The reinforced edge profile resists the thermal and mechanical shock common in heavy semi-finishing work.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Aluminum (6061 / 2024) | 400 - 1200 m/min | 0.15 - 0.40 mm/rev | 0.5 - 5.0 mm |
| Cast Aluminum (AlSi < 10%) | 300 - 800 m/min | 0.15 - 0.35 mm/rev | 0.5 - 4.0 mm |
| Brass / Copper | 200 - 600 m/min | 0.12 - 0.30 mm/rev | 0.3 - 3.0 mm |
Compatible Tooling Systems:
Precision matched for heavy-duty 16-size triangular holders:
- External Turning: STGCR 2020K16 / STGCR 2525M16
- Internal Boring (Large): S25S-STFCR16 / S32T-STFCR16
Machinist Tip: The "Workhorse" of Aluminum Boring
Optimizing the TCGT16T308 H01 for heavy industrial cycles:
Best for Surface Quality. H01 is the top choice for standard non-ferrous alloys. To maintain the "mirror finish," avoid re-cutting chips by using high-pressure air or coolant to clear the workspace.
Power over Precision. Choose the R0.8 when you need to "hog out" material quickly. It is much more durable than the 0.4 radius under high-vibration conditions or when the skin of the aluminum casting is uneven.
Pro Advice: Because of the large radius, this insert requires a rigid machine setup. If you experience surface chatter on thin parts, switch to the TCGT16T304 or TCGT16T302 to reduce radial pressure.
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.
