Iscar 5560581 Turning Insert VNMG331-M3M IC6025 Carbide

Product Description

The ISCAR 5560581 is a VNMG-style indexable turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, this insert is engineered primarily for turning stainless steel (ISO material group M). It features a 35-degree diamond shape, a 3/8-inch inscribed circle, and a 1/64-inch corner radius. The double-ended geometry and positive rake angle allow efficient chip evacuation and reduced cutting forces. The M3M chip breaker geometry is optimized for medium-depth cuts up to 3.00 mm, making it suitable for finishing and semi-finishing operations.

This insert is part of the Isoturn series and is intended for use in turning operations on stainless steel and similar work materials. It is compatible with VNMG-style toolholders that use clamp and pin holding methods. Typical applications include external and internal turning, facing, and profiling on CNC turning machines in job shop, production machining, and aerospace or medical component environments where stainless steel is a primary workpiece material. The ISO code for this insert is VNMG 331-M3M, and it conforms to ISO 13399 standards for cutting tool data representation.

Key Features

• Solid carbide substrate with CVD multilayer TiCN, Al2O3, and TiN coating for wear and heat resistance
• 35-degree diamond insert shape (V) with positive rake for reduced cutting forces
• M3M chip breaker geometry suited for medium finishing cuts up to 3.00 mm depth
• Double-ended insert provides two usable cutting edges per insert
• Conforms to ISO 13399 standard for interoperability with toolholder data systems
• Clamp and pin holding method compatible with standard VNMG toolholder pockets

Compatibility

Designed for use in VNMG-style indexable turning toolholders that accept clamp and pin retention. ISO code VNMG 331-M3M confirms fit within standard VNMG pocket geometry. Verify toolholder insert pocket size and clamping system before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware when seating the insert; do not overtighten the clamp screw by hand estimation alone. Inspect the insert pocket for debris or damage before seating a new insert to ensure proper contact and alignment.
