Iscar 5550523 WNMG330NF IC807 Turning Insert Carbide

Product Description

The ISCAR 5550523 is a WNMG330NF IC807 solid carbide turning insert designed for precision external turning operations on CNC lathes and turning centers. Featuring a TiAlN and TiN PVD coating applied over a submicron carbide substrate, this insert delivers wear resistance and thermal stability across a wide range of workpiece materials. The 80-degree trigon (W-shape) geometry with a neutral clearance angle and positive rake provides stable cutting action. The NF chip breaker geometry supports finishing and near-finishing passes. This insert is installed by CNC machinists and toolroom technicians in production and job-shop environments.

The ISCAR 5550523 is suited for universal application across multiple material groups, including steel (P), stainless steel (M), cast iron (K), hardened materials (H), and superalloys (S), as indicated by its multi-material grade classification. It is used in Isoturn-series toolholders accepting WNMG-style inserts. Typical applications include longitudinal turning, facing, and contouring on both ferrous and non-ferrous workpieces where a consistent surface finish is required.

Key Features

• IC807 grade with TiAlN and TiN PVD coating for extended tool life across universal material groups
• Submicron carbide substrate for improved toughness and edge integrity
• WNMG trigon insert shape (W) with 80-degree included angle for versatile cutting geometry
• NF chip breaker optimized for finishing and near-finishing depth-of-cut ranges
• Positive rake design reduces cutting forces and heat generation at the cutting edge
• Clamp and pin holding method ensures secure seating in compatible toolholders

Compatibility

Designed for use in Isoturn-series WNMG-style toolholders accepting inserts with a 3/8-inch inscribed circle and WNMG330 insert size code. Conforms to ISO 13399 standards.

Installation Notes

Insert installation and indexing should be performed by a qualified CNC machinist or toolroom technician with the spindle locked and machine in a safe, de-energized state. Use the appropriate torque wrench and clamp hardware specified for the toolholder to seat the insert correctly against the pocket locating surfaces. Inspect the insert pocket for chips or debris before seating a new insert. Never exceed the maximum depth of cut specified for the insert geometry and grade.
