Seco 02616001 Dnmg 432-MF4 TS2500 Carbide Turning Insert

Product Description

The SECO 02616001 is a DNMG 432-MF4 indexable turning insert manufactured from solid carbide with a multilayer PVD-applied TiAlN and TiN coating. Designed for precision metal removal on CNC lathes and turning centers, this insert features a 55-degree diamond (rhombic) shape, a 0.5000-inch inscribed circle, and a 0.0315-inch corner radius. The TS2500 grade targets superalloys and titanium as its primary workpiece materials while also performing in steel, stainless steel, and cast iron applications. With 4 cutting edges, a negative rake geometry, and an MF4 chip breaker optimized for finishing and medium machining, it delivers controlled chip flow and repeatable surface finishes. Licensed machinists and CNC operators in aerospace, energy, and general machining install this insert.

This insert is suited for turning, facing, boring, and back turning operations on CNC lathes and turning centers where consistent tool life across difficult-to-machine materials is required. The DNMG platform accepts clamp, pin, and lever-lock holding methods, giving it broad compatibility with standard DNMG-style toolholders. It is applicable across ISO material groups P (steel), M (stainless steel), K (cast iron), and S (superalloys and titanium). The MF4 chip breaker geometry supports light to medium depths of cut, making it well suited for finishing passes and semi-finish operations in production environments.

Key Features

• TS2500 carbide grade with multilayer PVD TiAlN and TiN coating for high wear resistance across ISO P, M, K, and S material groups
• 55-degree diamond insert shape (DNMG) with negative rake and negative side clearance for secure, stable seating
• MF4 chip breaker geometry optimized for finishing and medium machining operations
• 4 usable cutting edges per insert for extended tool economy
• Compatible with clamp, pin, and lever-lock toolholder systems
• Maximum depth of cut up to 0.5787 inches; insert length 1.2204 inches

Compatibility

Designed as a direct-fit replacement for DNMG 432-MF4 style toolholders accepting inserts with ANSI code DNMG432 and ISO code DNMG150408. Compatible holding methods include clamp, pin, and lever-lock systems. This insert conforms to ANSI and ISO standards for the DNMG insert geometry family.

Installation Notes

This insert is installed by qualified CNC machinists or tooling technicians. Always index or replace inserts with the machine powered down and the spindle fully stopped. Use the correct torque wrench or clamp screw driver specified by the toolholder manufacturer to seat the insert without cracking the carbide substrate. Inspect the toolholder pocket and seating surfaces for chips or wear before loading a fresh insert to ensure proper contact and runout control.
