Seco 02615962 Dnmg 432-MR4 TS2500 Carbide Turning Insert

Product Description

The SECO 02615962 is a solid carbide indexable turning insert in the DNMG 432-MR4 series, designed for precision metal cutting in demanding machining applications. It carries a multilayer TiAlN and TiN coating applied via PVD process, which extends tool life when cutting abrasive and heat-resistant materials. The insert features a 55-degree diamond shape, a 0.5000-inch inscribed circle, and a 0.0315-inch corner radius. With four cutting edges and a neutral hand orientation, it delivers efficient, repeatable performance for machinists running turning centers and CNC lathes in production environments.

This insert is engineered primarily for superalloys and titanium, carrying the S10 and S20 material grades. It also performs in steel, stainless steel, and cast iron applications. The MR4 chip breaker geometry with a T-Land cutting edge style suits multi-pass operations including back turning, boring, facing, and standard OD turning. The insert is compatible with clamping systems that accept clamp, pin, and lever lock holding methods, making it adaptable to a wide range of toolholders used in job shop and production machining environments.

Key Features

• Multilayer TiAlN and TiN PVD coating optimized for superalloys and titanium (material code S)
• MR4 chip breaker with T-Land cutting edge for controlled chip formation
• Four usable cutting edges per insert for extended tool economy
• Negative rake geometry with N clearance and M tolerance codes per ANSI and ISO standards
• Multi-use application: back turning, boring, facing, and turning in a single insert
• Maximum depth of cut of 0.5787 inches supports roughing and semi-finishing passes

Compatibility

Fits toolholders designed for DNMG 432 inserts using clamp, pin, or lever lock holding methods. ISO designation DNMG150408-MR4. Industry standard number DNMG432-MR4. Compatible with secondary workpiece materials steel (P), stainless steel (M), and cast iron (K) in addition to the primary superalloy and titanium (S) applications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver for the insert clamping screw to ensure proper seating without cracking the carbide substrate. Inspect the toolholder pocket and seating surfaces for chips or debris before each insert change.
