Value Collection ICP28100C Turning Insert VNMG431 TCN55

Product Description

The VALUE COLLECTION ICP28100C is a solid carbide turning insert designed for use on CNC lathes and manual turning centers. Classified under ANSI insert code VNMG431 and ISO insert code VNMG220404, this insert features a 35-degree diamond (rhombic) shape with a negative side clearance and a TiN (titanium nitride) coating in manufacturer grade TCN55. The inscribed circle measures 0.5 inches and the corner radius is 0.0156 inches (1/64 inches). The G-style chip breaker geometry helps manage chip flow during turning operations. Each unit is sold individually, with a minimum order quantity of 10 pieces.

This insert is suited for turning operations on workpiece materials corresponding to primary material codes M and P, which generally correspond to stainless steels and carbon or alloy steels. It is appropriate for external and internal turning, facing, and light profiling passes on lathes where VNMG-style toolholders are used. The negative relief angle geometry and clamp-and-pin holding method make it compatible with standard VNMG toolholder systems commonly found in production and job-shop turning environments.

Key Features

• ANSI insert code VNMG431 and ISO code VNMG220404 for straightforward toolholder matching
• TiN-coated solid carbide construction in grade TCN55 for wear resistance on steel and stainless workpieces
• 35-degree diamond insert shape with negative side clearance for stable, rigid clamping
• 0.0156-inch corner radius (1/64 inches) for moderate finish and edge strength balance
• G-style chip breaker for controlled chip evacuation during turning
• Compatible with clamp and pin holding methods standard to VNMG toolholder bodies

Compatibility

Designed as a direct-fit replacement for VNMG431-style turning inserts used in clamp-and-pin VNMG toolholders across CNC and manual lathe platforms. Verified compatible toolholder models or machine families were not specified in the available product data.

Installation Notes

Turning insert replacement is performed by machinists and CNC setup technicians. Always power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and insert clamp screws specified by the toolholder manufacturer — do not overtighten, as carbide inserts are brittle and can crack under excess clamping force. Inspect the toolholder seat and clamp components for wear or debris before seating a new insert.
