Seco 02615957 Cnmg 433-MR4 Turning Insert Carbide

Product Description

The SECO 02615957 is a CNMG 433-MR4 indexable turning insert engineered for demanding metal-cutting applications. It is manufactured from solid carbide with a multilayer PVD TiAlN and TiN coating and carries the TS2500 manufacturer grade. The insert features an 80-degree diamond (rhombic) shape, a 0.5 inch inscribed circle, a 3/64 inch (0.0472 inch) corner radius, and a 3/16 inch insert thickness. With 4 cutting edges, a negative rake geometry, and MR4 chip breaker design, it is suited for roughing and medium machining passes. Licensed machinists and CNC turning specialists install this insert in compatible toolholders using clamp, pin, or lever-lock holding methods.

This insert is designed for use in turning, facing, and boring operations on CNC lathes and turning centers in both production and job-shop environments. The TS2500 grade and MR4 chip breaker target superalloys and titanium as the primary workpiece material, with strong performance on steel, stainless steel, and cast iron as secondary materials. Grade characteristics span high wear-resistance to high toughness across P, M, K, and S material codes, making this insert adaptable across a broad range of workpiece materials. Maximum depth of cut reaches 0.4606 inch. The insert conforms to ANSI code CNMG433 and ISO code CNMG120412.

Compatibility

Designed for use in CNMG-style toolholders that accept a 0.5 inch inscribed circle insert with clamp, pin, or lever-lock holding. Suitable for turning, facing, and boring operations on CNC lathes and turning centers. Compatible workpiece materials include superalloys, titanium, steel, stainless steel, and cast iron per material codes P, M, K, and S.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torque driver for the insert screw or clamping mechanism per the toolholder manufacturer's specifications. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper seating and prevent edge chipping on first cut.
