Iscar 5504092 Cnmg 430-SF IC-520N Turning Insert

Product Description

The ISCAR 5504092 is a CNMG 430-SF turning insert from the Isoturn series, manufactured in cermet substrate with a PVD-applied TiCN and TiN coating. It carries an 80-degree diamond shape (insert shape code C) with a 0-degree relief angle (clearance code N) and tolerance code M. The inscribed circle measures 0.5 inches, insert length is 0.5079 inches (12.90 mm), and the corner radius is 0.0079 inches. Designed for external turning operations, this insert is held by clamp or pin and is suited for finish to semi-finish cutting passes where edge consistency and wear resistance are required. Licensed machinists and CNC lathe operators are the primary installers.

The 5504092 is engineered for turning stainless steel (ISO material code M) and carbon and alloy steels (ISO material code P). Its SF chip breaker geometry is optimized for stable chip formation and low cutting forces, making it well suited for finish turning on parts where surface finish and dimensional accuracy are critical. The maximum depth of cut is 0.0787 inches (2.00 mm). It conforms to ISO 13399 standards and carries material grades C6 and C7, placing it in the coated cermet category used across both CNC production and manual turning centers.

Key Features

• Cermet substrate with PVD TiCN and TiN coating for wear resistance and edge sharpness on steel and stainless steel
• SF chip breaker geometry promotes controlled chip flow at finish to semi-finish depths of cut
• 80-degree diamond insert shape provides two usable cutting edges per insert
• Corner radius of 0.0079 inches supports tight-tolerance surface finish requirements
• Compatible with clamp and pin insert holding methods for secure, repeatable seating
• Conforms to ISO 13399 for standardized tool assembly and data exchange

Compatibility

Designed as an OEM-style replacement turning insert for toolholders accepting CNMG 430 geometry with clamp or pin retention, suitable for CNC and manual lathes used in steel and stainless steel turning applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or indexing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not substitute fasteners. Inspect the insert pocket and seating surface for chips or debris before placing a new insert to ensure proper contact and prevent premature edge failure.
