Iscar 5507757 Carbide Turning Insert 80 Deg Trigon IC8150

Product Description

The ISCAR 5507757 is a WNMG433GN solid carbide turning insert finished with a CVD-applied TiCN and Al2O3 multilayer coating in the IC8150 grade. It features an 80-degree trigon (W) insert shape with a 0.5 inch inscribed circle, a 3/64 inch (0.0469 inch) corner radius, and an insert length of 8.70 mm (0.3425 inches). The GN chip breaker geometry is designed for controlled chip evacuation during turning operations. This insert is used by CNC machinists and turning center operators in production and job-shop environments where consistent tool life on cast iron and steel workpieces is required.

This insert is suited for external and internal turning applications on cast iron (ISO K) and steel (ISO P) workpieces. The IC8150 grade with CVD coating performs reliably in medium to rough turning conditions where heat resistance and wear resistance are priorities. Maximum depth of cut is 4.50 mm (0.177 inches). The insert belongs to ISCAR's Isoturn series, which covers a broad range of standard negative-rake turning geometries. It is held in the toolholder via clamp and pin methods, compatible with standard WNMG toolholder pockets.

Key Features

• IC8150 grade with CVD TiCN and Al2O3 multilayer coating for extended tool life on steel and cast iron
• 80-degree trigon insert shape (W) with WNMG433GN designation for negative-rake turning
• 0.5 inch inscribed circle with 3/64 inch corner radius for medium to rough turning profiles
• GN chip breaker geometry supports controlled chip formation across a range of feed rates
• Maximum depth of cut of 4.50 mm (0.177 inches) supports productive material removal rates
• Conforms to ISO 13399 tooling data standards for CAM and tool management integration

Compatibility

Designed for use in standard WNMG toolholder pockets that accept clamp and pin insert holding methods. Compatible with workpiece materials classified as cast iron (ISO K) and steel (ISO P). This insert is part of the ISCAR Isoturn series.

Installation Notes

Insert seating and clamping should be performed with the machine fully powered down and the spindle locked. Use the appropriate ISCAR or compatible WNMG toolholder and ensure the insert pocket and seating surfaces are clean and free of debris before seating. Clamp torque should follow the toolholder manufacturer's specification. Inspect the insert seat and clamp screw for wear at each insert change.
