Original Sweden SECO WNMG080404 PVD Coated Turning Insert for Semi-Finish Turning of Stainless Steel Titanium Nickel Superalloy
Product Overview
The SECO WNMG080404-MF1 TH1000, WNMG080408-MF1 TH1000, WNMG080404-MF1 CP200, WNMG080408-MF1 CP200 are original Swedish negative 80° WN trigon indexable turning inserts under Seco’s universal finishing series, equipped with exclusive MF1 semi-finish chipbreaker geometry, two mainstream high-performance PVD coating grades TH1000 and CP200, and two standard nose radius options R0.4 & R0.8.
MF1 chipbreaker is specially optimized for sticky hard-to-cut materials including stainless steel, titanium alloy and nickel-based superalloy, delivering low cutting resistance and stable short chip evacuation. TH1000 adopts TiSiN-TiAlN nanolaminate ultra-hard coating for hardened steel up to HRC62 and interrupted superalloy cutting; CP200 is a fine-grain PVD grade dedicated to continuous high-speed finishing of superalloy & stainless steel with excellent anti-built-up edge performance. This single-sided insert carries 6 usable cutting edges, perfectly matched with MWLNR08/MWLNL08 external turning tool holders for OD turning, facing and light internal boring on CNC lathes, widely applied in aerospace, medical equipment, auto engine and energy component precision mass production.

- External OD turning, end facing and light internal boring for hard-to-cut sticky alloy components on CNC lathes
- Continuous high-speed long-stroke machining of stainless steel pipe joints and hydraulic valve bodies (CP200 first choice)
- Interrupted cutting with keyways, uneven stock allowance and hardened surface skin layer (TH1000 first choice)
- Automated batch production requiring consistent ultra-smooth workpiece surface finish and long stable tool life
- Multi-material mixed processing workshops covering stainless steel, titanium alloy and low-hardness quenched steel
- Exclusive MF1 alloy-specialized chipbreaker: Highly positive inner rake design greatly reduces cutting force and workpiece work-hardening, generates short controllable curled chips to eliminate chip winding and scratching on finished surfaces
- Dual professional coating grades for differentiated scenarios:
TH1000 ultra-hard nano coating delivers outstanding wear resistance and edge toughness, reliable for intermittent cutting and hardened steel machining up to HRC62Seco Tools
CP200 low-friction fine-grain coating effectively suppress built-up edge, maintains stable finish quality in long continuous superalloy high-speed turning - Negative 80° trigon 6-edge structure: Six usable cutting corners maximize material utilization rate, drastically cutting long-term tool procurement cost for mass production factories
- 0° negative relief ultra-rigid cutting edge: Strong anti-chipping performance under medium feed and interrupted cutting, avoids frequent insert replacement during difficult alloy processing
- Low-friction PVD coating technology: Minimizes cutting heat accumulation, reduces thermal flank wear and extends service life by over 40% compared with ordinary universal carbide inserts
- Global standard WNMG08 size dimension: Fully interchangeable with all MWLNR08 series turning holders worldwide, easy unified spare part inventory management for foreign trade clients
