The Original Korloy WNMG080404-HS PC5300 (ANSI: WNMG 431-HS) is a highly versatile 80° Trigon Turning Insert designed for Universal Precision Finishing. Featuring the legendary PC5300 PVD Grade, this insert is the ultimate "problem solver" for workshops machining a variety of materials, including Steel, Stainless Steel, and Exotic Alloys. The HS Chipbreaker provides an ultra-sharp edge that ensures clean cuts and excellent chip control, even at low depths of cut and light feed rates.
The Universal Flagship: PC5300 is engineered for maximum toughness. If you need one insert that can handle a 304 stainless job in the morning and an alloy steel job in the afternoon without compromising tool life or surface finish, this is your best choice.
Technical Specifications (ISO vs. ANSI):
| ISO Designation | WNMG 080404-HS |
| ANSI Designation | WNMG 431-HS |

Cutting Parameters (Recommended):
PC5300 provides a wide working window. Here are the recommended starting points:
| Material | Cutting Speed (Vc) | Feed Rate (fn) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 150 - 250 m/min | 0.05 - 0.20 mm/rev | 0.2 - 1.5 mm |
| Stainless Steel (304/316) | 100 - 180 m/min | 0.05 - 0.15 mm/rev | 0.2 - 1.2 mm |
Compatible Tool Holders:
Fits all standard tool holders for 80-degree trigon inserts:
- External Turning: MWLNR/L Series (Standard Holders)
- Internal Boring: S-MWLNR/L Series (Precision Boring)
Core Performance Benefits:
- High Edge Toughness: The PC5300 substrate is exceptionally resistant to chipping, making it reliable for light interrupted cuts and unstable setups.
- Exceptional Heat Resistance: Advanced PVD coating maintains hardness at high temperatures, extending tool life during dry or high-speed machining.
- Mirror Surface Finish: The HS chipbreaker's positive rake angle "slices" the material, reducing radial pressure and eliminating chatter.
- Maximum Economy: Provides 6 usable edges—offering significantly lower tooling costs compared to CNMG or CCMT inserts.

Grade Selection Pro-Tip
PC5300 vs. PC9030: While PC9030 is the specialist for Stainless Steel, PC5300 is your "Universal" go-to. If you predominantly machine stainless, choose PC9030. If you switch between Steel and Stainless frequently, PC5300 will provide more consistent results across both materials.
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.
