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.

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.
