Seco 02616002 Dnmg 433-MF4 TS2500 Carbide Turning Insert

Product Description

The SECO 02616002 is a DNMG 433-MF4 series indexable turning insert manufactured from solid carbide with a multilayer TiAlN and TiN PVD coating. The insert carries the TS2500 manufacturer grade and is engineered primarily for cutting superalloys and titanium, with secondary capability in steel, stainless steel, and cast iron. It features a 55-degree diamond shape, a 0.5 inch inscribed circle, a 3/64 inch (0.0472 inch) corner radius, and 4 cutting edges. The MF4 chip breaker geometry is chamfered and honed for controlled chip formation in demanding materials. Licensed machinists and CNC turning specialists use this insert in production and job-shop environments where tool life and surface finish consistency in difficult workpiece materials are critical.

This insert is suited for external turning, facing, boring, and back turning operations on CNC lathes and turning centers. Its negative rake geometry and DNMG-MF4 series designation make it compatible with standard DNMG-style toolholders using clamp, pin, or lever lock holding methods. Primary target materials are superalloys and titanium (ISO material code S, grades S10 and S20). It also performs in steel (P), stainless steel (M), and cast iron (K) applications where a medium-finishing insert geometry is appropriate. The ISO designation is DNMG150412-MF4 and the industry standard number is DNMG433-MF4.

Key Features

• TiAlN and TiN multilayer PVD coating for heat resistance and extended tool life in superalloys and titanium
• MF4 chip breaker geometry with chamfered and honed cutting edge for controlled chip flow on tough materials
• 4 indexable cutting edges per insert for maximum cost efficiency
• Negative rake, neutral hand — fits standard DNMG toolholders with clamp, pin, or lever lock retention
• Maximum depth of cut of 0.563 inch supports a wide range of roughing to medium-finishing passes
• Compliant with ANSI and ISO indexable insert standards

Compatibility

Designed for use in DNMG-style toolholders accepting clamp, pin, or lever lock holding methods. Compatible with multi-use turning applications including back turning, boring, facing, and turning. Primary workpiece material code S (superalloys and titanium); secondary codes P (steel), M (stainless steel), and K (cast iron). ISO insert designation DNMG150412-MF4; industry standard number DNMG433-MF4.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing the insert. Seat the insert fully and flat in the toolholder pocket before engaging the clamp, pin, or lever lock mechanism. Inspect the insert pocket and seating surface for chips or debris prior to indexing to avoid seating errors that can affect surface finish and tool life.
