Description
The SECO 02730824 is a solid carbide turning insert in the WNMP-MF1 series, grade TH1000, designed for precision metal cutting in demanding machining environments. The insert features a PVD-applied multilayer TiAlSiN coating and an MF1 chip breaker geometry suited for finishing and semi-finishing operations. With an 80-degree trigon shape, a 0.5000-inch inscribed circle, and a 0.0315-inch corner radius, it delivers consistent edge performance across boring, facing, and turning applications. The honed cutting edge style and negative rake angle support stable engagement on difficult workpiece materials. This insert is sold individually with a minimum order quantity of 10 units.
This insert is engineered primarily for superalloys and titanium (ISO material codes S and H), making it well suited for aerospace, power generation, and precision manufacturing operations where tool life and surface integrity are critical. The MF1 chip breaker promotes controlled chip evacuation at moderate depths of cut up to 0.3307 inches. Holding methods include clamp, pin, and lever lock configurations, providing flexibility across compatible toolholders. The insert complies with both ANSI and ISO standards, and its ISO code equivalent is WNMG080408-MF1.
Key Features
- TH1000 grade with PVD multilayer TiAlSiN coating for heat and wear resistance in superalloy and hard material cutting
- 80-degree trigon insert shape with 6 cutting edges for extended tool life per insert
- MF1 chip breaker geometry optimized for finishing and semi-finishing passes
- Honed cutting edge style with negative rake for stable, predictable engagement
- Compatible with clamp, pin, and lever lock toolholder systems
- Meets ANSI and ISO standards; ISO equivalent WNMG080408-MF1
Compatibility
Designed for use in WNMP-series toolholders that accept a 0.5000-inch inscribed circle trigon insert with clamp, pin, or lever lock holding methods. Intended for multi-use applications including boring, facing, and turning. ISO code WNMG080408-MF1 may be used to cross-reference compatible toolholder systems per ISO standard fitment.
Installation Notes
Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or replacing inserts. Secure the insert using the appropriate clamp, pin, or lever lock mechanism per the toolholder manufacturer’s instructions. Inspect the insert pocket and seating surface for debris or damage before installation to ensure proper edge presentation and prevent premature failure.
