Iscar 5550243 CNMG431NF IC807 Carbide Turning Insert

Product Description

The ISCAR 5550243 is a solid carbide turning insert in the CNMG431NF geometry, designed for external and internal turning operations on CNC lathes and turning centers. Carrying the IC807 manufacturer grade with a dual-layer TiN and TiAlN PVD coating, this insert delivers wear resistance and thermal stability across a broad range of workpiece materials. The 80-degree diamond (C) insert shape provides a strong cutting edge, while the NF chip breaker geometry promotes positive rake cutting action for efficient chip control. Machining technicians and CNC operators install this insert using clamp or pin holding methods on compatible toolholders.

This insert is suited for universal application across steel, stainless steel, cast iron, non-ferrous, and high-temperature alloy workpieces, reflected in its ISO workpiece material codes H, K, M, P, and S. It is part of the Isoturn series and is also applicable for boring operations, making it a multi-use option in production and job-shop environments. The NF chip breaker targets finish to light roughing passes within the rated depth-of-cut range.

Key Features

• IC807 grade with TiN and TiAlN PVD dual coating for extended tool life across diverse materials
• 80-degree diamond insert shape (CNMG style) with positive rake for reduced cutting forces
• NF chip breaker geometry engineered for controlled chip formation
• Clamp and pin holding compatibility for secure seating in standard CNMG toolholders
• Multi-use capability including turning and boring applications
• Meets ISO 13399 standards for tooling data representation

Compatibility

Designed as an OEM-style replacement or direct-fit insert for standard CNMG431 toolholders. No specific model compatibility data was provided in the product input; verify toolholder pocket geometry and insert seat dimensions before ordering.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex wrench to torque the clamp or pin to the toolholder manufacturer specification. Inspect the insert seat and clamp for debris or damage before installing a new insert to ensure proper seating and cutting edge registration.
