Seco 03094136 CNMG431-MF2 TP3501 Turning Insert Carbide

Product Description

The SECO 03094136 is a CNMG431-MF2 series indexable turning insert manufactured from solid carbide and coated via CVD with a multilayer TiCN, Al2O3, and Cr Duratomic coating. Designated grade TP3501, this insert features a neutral hand orientation, an 80-degree diamond shape, a 0.5-inch inscribed circle, and a 1/64-inch (0.0157 inch) corner radius. The MF2 chip breaker geometry with a chamfered and honed cutting edge style is engineered for medium finishing operations. With four usable cutting edges per insert, it delivers consistent performance in boring, facing, and turning applications across steel and stainless steel workpieces.

This insert is suited for CNC turning centers and manual lathes operating on steel (ISO P) and stainless steel (ISO M) workpieces, covering material grades P20, P30, and P40. The MF2 chip breaker geometry is particularly effective in medium finishing passes where controlled chip formation and edge stability are critical. Typical users include machinists and CNC operators working in job shops, production turning cells, and maintenance machining environments. The insert seats in toolholders compatible with clamp, pin, or lever lock holding methods and conforms to both ANSI and ISO standards.

Key Features

• Duratomic CVD multilayer coating (TiCN, Al2O3, Cr) for extended tool life on steel and stainless steel
• MF2 chip breaker with chamfered and honed cutting edge for controlled chip formation in medium finishing
• Four cutting edges per insert reduce cost-per-edge in high-volume turning operations
• 80-degree diamond insert shape (ISO Code C) with negative rake and 0-degree relief angle for strong edge geometry
• Compatible with clamp, pin, and lever lock toolholder systems
• Conforms to ANSI and ISO standards; ISO designation CNMG120404-MF2

Compatibility

Designed for use in CNMG-style toolholders that accept clamp, pin, or lever lock holding methods. Confirmed primary workpiece materials are steel (ISO P, grades P20, P30, P40) and stainless steel (ISO M). Multi-use application across boring, facing, and turning operations. ISO industry standard number CNMG120404-MF2 and ANSI industry standard number CNMG431-MF2 can be used to cross-reference compatible toolholder systems.

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 appropriate torque wrench per toolholder manufacturer specifications when securing the clamping screw or lever lock mechanism. Inspect the insert seat and shim for debris or damage before seating a new insert to ensure proper contact and prevent premature edge failure.
