Price shown is a starting point. Contact us for a precise quote based on your requirements.
The Original Korloy CNMG120404-HS PC5300 (ANSI Standard: CNMG 431) is the ultimate universal finishing insert designed for maximum versatility. Featuring the high-toughness PC5300 PVD coating, this insert excels across multiple material groups, including Steel (P), Stainless Steel (M), Cast Iron (K), and Exotic Alloys (S). The specialized HS chipbreaker provides a sharp cutting edge that prevents work hardening and delivers superior surface finishes even in unstable machining conditions or interrupted cuts.
Universal Performer: PC5300 is our most recommended grade for shops that machine a variety of materials and require a single, reliable insert to handle everything from alloy steel to 316 stainless.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CNMG120404-HS |
| ANSI Code | CNMG 431 |
| Grade | PC5300 (Universal PVD Premium) |
| Chipbreaker | HS (Sharp Precision Finishing) |
Core Performance Benefits:
- Multi-Material Excellence: Reduces tool inventory by performing exceptionally well in steel, stainless steel, and cast iron.
- Extreme Toughness: Specialized PVD coating prevents micro-chipping and survives interrupted cuts where other finishing inserts fail.
- Superior Surface Control: The HS geometry is designed for light depths of cut, ensuring clean chip evacuation and a mirror-like finish.
- Low Cutting Force: Sharp edge reduces pressure on the workpiece, making it ideal for thin-walled parts or long, slender shafts.
Recommended Cutting Parameters:

Pro Tip: PC5300 vs. PC9030 for Finishing
Which PVD grade should you choose for your shop?
Best for versatility. Superior toughness for interrupted cuts and mixed-material production.
Best for dedicated high-volume stainless steel. Offers maximum resistance to adhesive wear and built-up edge.
Machinist's Hint: If you are working on a job with unknown material or heavy vibration, start with PC5300—its high toughness is your safety net against sudden tool failure.
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.
