Product Description
The SECO 02730811 is a solid carbide turning insert in the CNMP 432-MF1 series, designed for precision metal cutting in demanding machining environments. It carries a TiAlSiN multilayer PVD coating and an MF1 chip breaker geometry optimized for finishing operations. The insert features an 80-degree diamond (rhombic) shape with a 0.5 inch inscribed circle, a 0.0315 inch corner radius, and four usable cutting edges. It is intended for CNC lathe and turning center applications where tool life and surface finish are critical priorities for machinists working in high-production or job-shop settings.
This insert is rated for primary use on superalloys, titanium, and hardened materials material codes S and H making it well suited for aerospace, medical, and energy-sector component machining. It also supports secondary workpiece materials including cast iron (K), general steel (M), and stainless (P). Multi-use applications include turning, boring, and facing operations. The neutral hand orientation accommodates a wide range of toolholders. The MF1 chip breaker geometry delivers controlled chip formation at light-to-moderate depths of cut up to 0.4764 inch.
Key Features
- TiAlSiN multilayer PVD coating provides high wear resistance for superalloys and hardened materials
- 80-degree diamond insert shape with negative rake and negative side clearance for stable clamping
- MF1 chip breaker geometry engineered for finishing passes with controlled chip evacuation
- Four cutting edges per insert reduce per-edge tooling cost
- Compatible with clamp, pin, and lever-lock insert holding methods
- Honed cutting edge style reduces microchipping on difficult-to-machine alloys
- Meets ANSI and ISO dimensional standards (ANSI: CNMP432, ISO: CNMP120408)
Compatibility
Designed to fit toolholders configured for CNMP 432 / CNMP120408 insert geometry using clamp, pin, or lever-lock holding methods. Verify toolholder pocket style and seating surface before installation. No specific machine or toolholder model compatibility was provided by the manufacturer for this listing.
Installation Notes
Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and manufacturer-specified clamping hardware to seat the insert fully against the pocket; do not overtighten by feel alone. Inspect the insert pocket and seating surface for chips or debris before each insert change to prevent premature edge failure.
