Korloy TPGH080202L-CRT PC5300 (R0.2) PVD Insert for Stainless Steel (10pcs)
Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy TPGH080202L-CRT PC5300 (ANSI: TPGH 1.51.50.5L-CRT) is a high-performance PVD Coated Turning Insert designed for Precision Finishing in demanding materials. Featuring the ultra-tough PC5300 Universal Grade, this insert excels in machining Stainless Steel (M), Heat Resistant Alloys (S), and Steel (P). The CRT chipbreaker and sharp 0.2mm radius make it the premier choice for Swiss-type lathes where precision, chip control, and edge reliability are paramount.
The Toughness Specialist: Unlike brittle cermet grades, PC5300 features a specialized PVD coating with excellent lubrication and heat resistance. It is specifically engineered to handle the "gummy" nature of 304/316 stainless steel and the mechanical shocks of interrupted cuts.
Technical Specifications (Metric & Imperial):
| ISO Designation | TPGH 080202L-CRT |
| ANSI Designation | TPGH 1.51.50.5L-CRT |
| Inscribed Circle (IC) | 4.76 mm / (3/16") |
| Thickness (S) | 2.38 mm / (3/32") |
| Corner Radius (r) | 0.2 mm / (0.008") |
| Grade | PC5300 (Universal Tough PVD) |
Core Performance Benefits:
- Universal Compatibility: One grade to handle Stainless Steel, Steel, and Super Alloys—perfect for shops with diverse job requirements.
- Sharp CRT Edge: Designed for finishing cuts (ap < 0.5mm), providing excellent chip breaking and preventing long "bird-nesting" chips.
- Extreme PVD Adhesion: The coating stays on the edge longer, preventing the premature peeling that often occurs when machining stainless steel.
- Interrupted Cut Stability: High toughness substrate makes it safer for parts with holes, slots, or uneven surfaces compared to cermet.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless Steel (304/316) | 80-180 m/min | 0.03-0.10 mm/rev | 0.05-0.5 mm |
| Alloy Steel / 4140 | 120-220 m/min | 0.03-0.12 mm/rev | 0.05-0.6 mm |
| Titanium Alloys | 40-80 m/min | 0.02-0.08 mm/rev | 0.05-0.4 mm |
Compatible Tool Holders:

Machinist Tip: PC5300 vs. CN2000 Cermet
Which precision grade should you choose?
Best for Versatility. Use this for stainless steel, interrupted cuts, or when you need a "tougher" edge that won't chip under heavy chip loads or unstable conditions.
Best for Surface Finish. Choose CN2000 for high-speed finish passes on clean steel where a "mirror finish" is required. It is harder but more brittle than PC5300.
Pro Advice: When machining 316 Stainless, use a high-pressure coolant to keep the cutting zone cool. PC5300 is designed to resist thermal shock, but consistent cooling will double your tool life.
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.
