Seco 02615973 Snmg 543-MR4 TS2500 Carbide Turning Insert

Product Description

The SECO 02615973 is a solid carbide indexable turning insert in the SNMG 543-MR4 series, designed for high-performance metal cutting on CNC lathes and turning centers. It carries a multilayer PVD coating combining TiAlN and TiN for wear resistance and thermal stability. The insert features a 90-degree square shape with a negative rake geometry, a T-Land cutting edge style, and the MR4 chip breaker configuration. With an inscribed circle of 0.6250 inches and a corner radius of 0.0472 inches, the 02615973 delivers controlled chip formation and consistent tool life in demanding turning, facing, and boring operations.

This insert is optimized for cutting superalloys and titanium as its primary workpiece materials, with strong secondary performance on steel, stainless steel, and cast iron. It is suited for both roughing and semi-finishing passes in aerospace, energy, and general machining environments where heat-resistant alloys are common. The neutral hand orientation supports flexible programming on multi-axis CNC equipment. Compatible holding methods include clamp, pin, and lever lock toolholders, making it adaptable to a wide range of insert pocket designs.

Key Features

• Negative rake, 90-degree square geometry with neutral hand orientation
• Multi-use design supports turning, facing, and boring in a single insert style

Compatibility

Designed for SNMG-style indexable toolholders accepting clamp, pin, or lever lock retention. Compatible with holders sized for a 0.6250-inch inscribed circle insert with a 0.2500-inch hole diameter and 0.2500-inch insert thickness. Meets ANSI and ISO standards; ISO code SNMG150612-MR4, industry standard number SNMG543-MR4.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine fully stopped and in a safe lockout state before indexing or replacing inserts. Seat the insert firmly in the pocket and torque the clamping screw according to the toolholder manufacturer specifications. Inspect the insert pocket and seating surfaces for chips or debris before installation to ensure proper seating. Verify chip breaker orientation and insert hand match the programmed tool path before resuming cuts.
