The Original Korloy WNMG080408-HS PC5300 (ANSI: WNMG 432-HS) is the industry's premier Universal Finishing Insert. Engineered with the legendary PC5300 PVD Grade, this 80° Trigon insert is a high-toughness "all-rounder" capable of delivering exceptional results in Steel, Stainless Steel, and difficult-to-cut alloys. The HS Chipbreaker features an ultra-sharp rake angle, while the 0.8mm (1/32") radius provides the necessary edge strength for stable, high-quality finishing pass after pass.
The Multi-Material Powerhouse: If your workshop handles a variety of materials, the PC5300 grade is your best investment. It effectively bridges the gap between specialized steel and stainless steel inserts, reducing the need for extensive tooling inventory while maintaining high surface finish standards.

| Stainless Steel (304/316) | 90 - 170 m/min | 0.08 - 0.20 mm/rev | 0.5 - 2.0 mm |
| Ductile Iron (GGG) | 120 - 200 m/min | 0.10 - 0.22 mm/rev | 0.5 - 2.0 mm |
Compatible Tool Holders:
Universal fit for all standard MWLNR/L type tool holders:
- External Turning: MWLNR/L Series (Industry Standard)
- Internal Boring: S-MWLNR/L Series (Rigid Boring Bars)
Core Performance Benefits:
- Ultra-High Edge Toughness: Specialized sub-micron substrate prevents chipping even during light interrupted cuts or in unstable setups.
- Multi-Layer PVD Coating: Advanced thermal barrier technology extends tool life during dry machining and high-speed cycles across multiple material types.
- Precision R0.8 Radius: Offers a more durable edge than R0.4, allowing for increased feed rates while still achieving high-quality surface finishes.
- Unmatched 6-Edge Economy: Trigon geometry provides 50% more productivity per insert than traditional CNMG shapes, significantly lowering tooling overhead.

Selection Pro-Tip: R0.8 vs R0.4
Choose WNMG080408-HS (R0.8) if you need a more robust cutting edge to handle slightly higher feeds or semi-finishing tasks. If you are working on very slender parts or require the highest possible dimensional precision with minimal cutting pressure, consider the WNMG080404-HS (R0.4) version.
Packaging: 10 pieces per box.
