The Original Korloy CNMG120408-HS PC5300 (ANSI Standard: CNMG 432) is a high-performance universal semi-finishing insert engineered for maximum reliability. By combining a tough sub-micron substrate with an advanced PVD coating, the PC5300 grade delivers exceptional results in Steel (P), Stainless Steel (M), and Cast Iron (K). The HS chipbreaker provides a sharp cutting action that excels at breaking chips even in gummy materials, while the 0.8mm (1/32") nose radius ensures the edge strength needed for versatile daily machining.
Why Choose PC5300? It is the perfect "Problem Solver" grade. If you face chipping issues with CVD grades or need one insert that can handle multiple materials efficiently, PC5300 is your best choice.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CNMG120408-HS |
| ANSI Code | CNMG 432 |
| Grade | PC5300 (Universal PVD High-Toughness) |
| Nose Radius | 0.8 mm (1/32") - General Purpose |
Core Performance Benefits:
- Extreme Chipping Resistance: The high-toughness PVD coating is designed to survive heavy interruptions and unstable machining setups.
- Multi-Material Versatility: Optimized for steel, stainless steel, and cast iron, significantly reducing tool inventory costs.
- Effective Chip Control: The HS geometry features a sharp rake angle that forces chips to curl and break at light-to-medium depths of cut.
- Extended Tool Life: Advanced PVD technology provides superior heat resistance and prevents built-up edge (BUE) in stainless applications.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Alloy Steel (P) | 140 - 260 m/min | 0.10 - 0.30 mm/rev | 0.5 - 3.5 mm |
| Stainless Steel (M) | 90 - 200 m/min | 0.08 - 0.25 mm/rev | 0.5 - 3.0 mm |
| Cast Iron (K) | 110 - 230 m/min | 0.12 - 0.35 mm/rev | 0.8 - 3.5 mm |
Compatible Tool Holders:
Maintain maximum rigidity with these high-performance D-Type or M-Type holders:
- External Turning: PCLNR/L 2020K12 / PCLNR/L 2525M12 / DCLNR/L 2525M12
- Internal Boring: S25S-PCLNR12 / S32T-PCLNR12 / S40T-PCLNR12
The Hybrid Solution: PC5300 vs. NC3120
How to maximize your tool life in different conditions:
Best for unstable machines, interrupted cuts, and mixed material batches. Extreme toughness prevents chipping.
Best for dedicated high-speed steel turning in stable, continuous cuts. Higher wear resistance but less impact strength.
Machinist's Tip: Use PC5300 for your first pass on rough castings or forged parts where the surface is uneven. Its high toughness will protect the edge from premature 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.
