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 |

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.
