Seco 02959831 Turning Insert SNMG432-MF2 TP2501 Carbide

Product Description

The SECO 02959831 is a solid carbide turning insert in the SNMG-MF2 series, designed for precision metal cutting in CNC lathe and turning center applications. It carries the TP2501 manufacturer grade with a Duratomic CVD multilayer coating — TiCN, Al2O3, and Cr — engineered for wear resistance and thermal stability at the cutting edge. The insert features a 90-degree square shape with a negative rake angle, a 0.5 inch inscribed circle, and a 0.0315 inch corner radius. The MF2 chip breaker geometry and chamfered-and-honed cutting edge style support controlled chip formation during medium to light turning passes. Eight cutting edges per insert make this a cost-effective option for high-volume production environments.

This insert is suited for boring, facing, and turning operations on steel, stainless steel, and cast iron workpieces. It falls within material grade classifications P10, P20, P30, and P35, making it most at home in continuous to lightly interrupted cuts on low-to-medium alloy steels and austenitic stainless. Typical install scenarios include production turning on CNC lathes where clamp, pin, or lever-lock toolholders accept SNMG-style inserts. The insert is sold individually but requires a minimum order of 10 units per transaction.

Key Features

• Duratomic CVD coating: TiCN, Al2O3, and Cr layers for thermal and abrasion resistance
• MF2 chip breaker geometry for controlled chip formation in finishing and medium turning
• 8 usable cutting edges per insert maximizes tool life per unit cost
• Chamfered and honed cutting edge style reduces microchipping at the edge line
• Neutral hand orientation compatible with both right- and left-hand toolholders
• Compatible with clamp, pin, and lever-lock insert holding methods
• Conforms to ANSI and ISO standards; ISO code SNMG120408-MF2

Compatibility

Designed for use in SNMG-style toolholders that accept clamp, pin, or lever-lock holding methods. Industry standard number SNMG432-MF2 and ISO code SNMG120408-MF2 govern toolholder fitment. Primary workpiece material is steel (ISO P); secondary materials are stainless steel (ISO M) and cast iron (ISO K). Suitable for boring, facing, and turning multi-use applications.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torque wrench for the clamping screw as specified by the toolholder manufacturer — no torque value is specified for this insert alone. Inspect the insert pocket and seating surface for chips or debris before securing the insert to ensure proper contact and edge alignment.
