Seco 02754834 CNMG431MF2 TP1030 Cermet Turning Insert

Product Description

The SECO 02754834 is a cermet turning insert in the CNMG-MF2 series, designed for high-precision metal cutting on CNC lathes and turning centers. Identified by industry standard number CNMG431-MF2 and ISO code CNMG120404-MF2, this insert features a multilayer TiAlSiN PVD coating under manufacturer grade TP1030. The 80-degree diamond shape provides a strong cutting edge geometry, while the MF2 chip breaker and chamfered-and-honed cutting edge style suit finishing and semi-finishing passes. The neutral hand orientation makes it adaptable across a wide range of toolholders. Licensed machinists and CNC operators install this insert for boring, facing, and turning applications.

This insert is intended for primary use on steel (ISO material code P, grades P10 and P15) and secondary use on stainless steel (ISO material code M). It is suited for both light and moderate depth-of-cut operations, with a maximum depth of cut of 0.4921 inches and a 0.0157-inch corner radius that supports fine surface finishes. The negative rake and 0-degree relief angle (clearance code N, tolerance code M) are typical of robust roughing-to-finishing transitions in production turning environments. Compatible with clamp, pin, and lever lock insert holding methods, the 02754834 integrates into standard CNMG-style toolholders used in residential shop and industrial production settings alike.

Key Features

• Multilayer TiAlSiN PVD coating under TP1030 grade for wear resistance on steel and stainless steel
• MF2 chip breaker with chamfered and honed cutting edge for controlled chip formation in finishing cuts
• 80-degree diamond insert shape (shape code C) with 4 usable cutting edges for extended tool life
• 0.4921-inch maximum depth of cut supports both light finishing and moderate semi-finishing passes
• Compatible with clamp, pin, and lever lock holding methods for broad toolholder flexibility
• Conforms to ANSI and ISO standards; multi-use for boring, facing, and turning operations

Compatibility

Designed as an OEM-style replacement or direct-fit option for standard CNMG-style toolholders accepting CNMG431 inserts with clamp, pin, or lever lock holding methods. Verify toolholder pocket geometry and insert size code 431 compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the pocket and torque the clamping screw to the toolholder manufacturer's specification — do not over-tighten, as cermet substrates are more brittle than carbide. Inspect the insert seat and chip breaker groove for debris before seating a new edge.
