Iscar 5508175 WNMG332TF IC8150 Turning Insert Carbide

Product Description

The ISCAR 5508175 is a WNMG332TF-geometry turning insert in the Isoturn series, grade IC8150. It is manufactured from solid carbide and finished with a multilayer CVD coating sequence of TiCN, Al2O3, TiCN, and TiN. The 80-degree trigon shape, combined with a 0-degree relief angle (clearance code N) and a positive rake, positions this insert for stable, productive cuts on cast iron and steel. The inscribed circle measures 0.375 inches, the insert length is 0.257 inches, and the corner radius is 0.031 inches. It is seated by clamp or pin holding methods. Machinists and CNC turning center operators install this insert in compatible WNMG-style toolholders for medium to finish turning operations.

This insert is intended for external and internal turning applications on cast iron (ISO material group K) and steel (ISO material group P) workpieces. It fits residential and industrial shop environments alike, from job shops running production turning programs to maintenance facilities performing shaft and bushing work. Maximum recommended depth of cut is 0.118 inches (3.00 mm). The TF chip breaker geometry is suited for controlled chip formation during light to medium feeds, reducing the risk of chip packing and tool damage on automated turning equipment.

Key Features

• Multilayer CVD coating: TiCN outer and inner layers with Al2O3 mid-layer for thermal barrier and wear resistance
• IC8150 grade optimized for cast iron and steel cutting (ISO K and P material groups)
• 80-degree trigon insert shape (code W) with positive rake for reduced cutting forces
• 0.031-inch corner radius for finish and medium turning operations
• Compatible with clamp and pin holding methods for secure seating in WNMG toolholders
• Conforms to ISO 13399 for standardized tool data exchange

Compatibility

Designed as an OEM-style replacement or direct-fit insert for WNMG332-style toolholders that accept a 0.375-inch inscribed circle trigon insert with clamp or pin retention. Primary workpiece materials are cast iron and steel per ISO material group codes K and P.

Installation Notes

This insert is installed by a machinist or CNC toolroom technician. Power down and lock out the turning center before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamp screw to secure the insert — do not overtighten by hand alone. Inspect the insert pocket and shim for wear or debris before seating a new insert to ensure proper contact and tool geometry.
