Description
The SECO 10028453 is a CNMG432-M3 series indexable turning insert manufactured from solid carbide with a CVD-applied Duratomic multilayer coating consisting of TiCN, Al2O3, and Cr. It carries manufacturer grade TM1501 and is designed for negative rake, neutral-hand turning operations on CNC lathes and turning centers. The insert features an 80-degree diamond shape, a 0.5079-inch length, a 0.5-inch inscribed circle, and a 0.0315-inch corner radius. Four cutting edges are available per insert. The M3 chip breaker geometry with a chamfered and honed cutting edge style makes this insert well-suited for medium-roughing to finishing passes.
This insert is intended for primary use on stainless steel (ISO material code M, grades M15, M20, M25) and secondary use on steel (ISO material code P). Typical applications include boring, facing, and turning operations in both production and job-shop environments. It is used by machinists and CNC operators in industries where close-tolerance turning of stainless and alloy steels is required. The insert conforms to both ANSI and ISO standards, with an ISO designation of CNMG120408-M3 and an industry standard number of CNMG432-M3.
Key Features
- CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for extended tool life on stainless and steel workpieces
- 80-degree diamond insert shape with negative rake and 0-degree relief angle (clearance code N, tolerance code M)
- M3 chip breaker with chamfered and honed cutting edge for controlled chip evacuation on medium cuts
- Four usable cutting edges per insert, reducing per-edge tooling cost
- Compatible with clamp, pin, and lever-lock insert holding methods
- Conforms to ANSI and ISO standards; ISO code CNMG120408-M3
Compatibility
Designed for use in CNMG-style toolholders that accept 432 series inserts with clamp, pin, or lever-lock holding methods. Suitable for turning, facing, and boring operations on stainless steel (M15, M20, M25 material grades) and steel. Multi-use application across compatible CNC and manual turning platforms.
Installation Notes
Installation is performed by machinists or CNC setup technicians. Power down or engage E-stop on the machine and ensure the spindle is fully stopped before indexing or replacing inserts. Use the appropriate torque wrench and seating tool for the toolholder clamping system (clamp, pin, or lever lock) to ensure proper seating without over-torquing. Inspect the insert pocket and shim for damage before installing a new insert.
