Korloy TPGH110302L-CRT CN2000 Precision Cermet Finishing Insert (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy TPGH110302L-CRT CN2000 is the premier Cermet Turning Insert for Heavy-Duty Precision Finishing. Featuring the largest 11-size triangular footprint in the TPGH family, this insert provides maximum stability and clamping force. The CN2000 Cermet Grade ensures a mirror-like surface finish by significantly reducing chemical affinity between the tool and the workpiece. Combined with a 0.2mm (0.008") corner radius and the CRT geometry, it allows for extremely fine detail work with microscopic precision.
The Cermet Performance Factor: CN2000 is not just a coating, but a specialized ceramic-metal substrate. It maintains a sharp edge far longer than carbide when running at high surface speeds, making it the industry standard for finishing high-precision components in the automotive and medical sectors.
Technical Specifications:
| ISO Designation | TPGH 110302L-CRT |
| Insert Shape | Triangular 11° Positive (T) |
| Inscribed Circle (IC) | 6.35 mm / (1/4") |
| Thickness (S) | 3.18 mm / (1/8") |
| Corner Radius (r) | 0.2 mm / (0.008") |
| Grade | CN2000 (Elite Mirror Finish Cermet) |
Core Performance Benefits:
- Maximum Rigid Support: The 11-size substrate offers superior resistance to vibration during high-speed finishing passes.
- Ultra-Low Ra Values: Capable of achieving surface finishes comparable to grinding, saving time and secondary costs.
- Extreme Thermal Stability: Resists thermal deformation, allowing for continuous machining without frequent tool offset adjustments.
- Sharp CRT Edge: Engineered for light depths of cut (0.03mm - 0.40mm) while ensuring consistent chip breaking.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon Steel (1045/S45C) | 180-420 m/min | 0.03-0.12 mm/rev | 0.05-0.5 mm |
| Alloy Steel (4140/SCM440) | 150-350 m/min | 0.03-0.10 mm/rev | 0.05-0.4 mm |
Compatible Tool Holders:
Optimized for 11-size triangular positive tool systems:
- External Precision Holders: STGCR 1212H11 / STGCR 1616H11
- Internal Boring Bars: S12M-STUPR11 / S16Q-STUPR11
Machinist Tip: The Cermet Rule of Three
To maximize the results of your TPGH110302L CN2000:
Never use Cermet on interrupted cuts (keyways, holes). The sudden impact will cause the 0.2mm radius to shatter due to Cermet's lower toughness compared to carbide.
If you see "tearing" on the surface, increase your Vc. Cermet requires heat to plasticize the material flow across the cutting edge for that mirror finish.
Pro Advice: The 11-size insert is the "muscle" of the TPGH family. Use it when you have sufficient space to ensure the most rigid setup possible, especially during internal boring.
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.
