Seco 03096305 Turning Insert CNMG432-M6 TP3501 Carbide

Product Description

The SECO 03096305 is a CNMG432-M6 series indexable turning insert manufactured from solid carbide with a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr. It carries manufacturer grade TP3501 and is designed for general turning, facing, and boring operations on CNC lathes and turning centers. The insert features an 80-degree diamond shape, a 0.5-inch inscribed circle, and a 1/32-inch (0.0315-inch) corner radius with a honed cutting edge style. The M6 chip breaker geometry and negative rake angle make this insert well suited for medium to roughing-depth cuts in steel and stainless steel applications. Qualified machinists and CNC operators are the primary installers of this insert type.

This insert is intended for use in steel (ISO material code P, grades P20, P30, and P40) as the primary workpiece material, with stainless steel (ISO material code M) as the secondary target material. Typical applications include external and internal turning, facing, and boring passes on production parts in job shops, aerospace, and general manufacturing environments. The CNMG432-M6 geometry fits a wide range of standard CNMG toolholders configured for clamp, pin, or lever-lock insert retention. The ISO equivalent designation is CNMG120408-M6, which can assist in cross-referencing compatible toolholder systems.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for elevated wear resistance and thermal stability
• M6 chip breaker geometry optimized for medium to rough turning in steel and stainless steel
• 4 cutting edges per insert maximizes tooling economy
• Negative rake, 0-degree relief angle (clearance code N) with honed edge for edge strength on interrupted and continuous cuts
• Maximum depth of cut of 0.4764 inches supports aggressive material removal rates
• Compatible with clamp, pin, and lever-lock toolholder retention methods
• Conforms to ANSI and ISO insert standards; industry standard number CNMG432-M6, ISO code CNMG120408-M6

Compatibility

Designed to fit standard CNMG-style toolholders that accept clamp, pin, or lever-lock retention. Compatible with toolholders specifying a 0.5-inch inscribed circle CNMG insert with a 0.2028-inch hole diameter. Suitable for boring, facing, and turning applications on steel (P20, P30, P40) and stainless steel workpieces. ISO equivalent designation CNMG120408-M6 can be used to match compatible toolholder references.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Always power down the machine and engage the spindle lock before seating or indexing an insert. Confirm the toolholder pocket and clamping mechanism are clean and free of chips before installing the insert. Follow the toolholder manufacturer's clamping torque specifications and consult applicable ANSI or ISO tooling standards for proper insert retention procedure.
