Iscar 5507828 Wnmg Turning Insert 3/8 Ic IC8250

Product Description

The ISCAR 5507828 is a WNMG-style solid carbide turning insert designed for precision external turning operations on CNC and manual lathes. It carries the IC8250 manufacturer grade and features a CVD-applied TiCN and Al2O3 multilayer coating for high wear resistance and thermal stability at the cutting edge. The insert has an 80-degree trigon (W) shape with a 3/8-inch inscribed circle, a 0.008-inch corner radius, and an NF chip breaker geometry. These characteristics make it well suited for finishing and semi-finishing passes where consistent surface finish and controlled chip formation are required. Licensed machinists and CNC turning specialists are the primary installers of this insert type.

The ISCAR 5507828 is engineered for turning applications involving steel and stainless steel workpiece materials, corresponding to ISO workpiece material codes P and M. The Isoturn series positions this insert for use in general-purpose external turning, facing, and profiling operations. The NF chip breaker geometry targets finishing cut depths, and the positive rake configuration reduces cutting forces on the workpiece. It is suited for use in production turning environments where repeatable tool life and predictable chip control are priorities.

Key Features

• IC8250 grade solid carbide substrate with CVD-applied TiCN and Al2O3 multilayer coating
• 80-degree trigon (W) insert shape with positive rake for reduced cutting forces
• NF chip breaker geometry optimized for finishing and light semi-finishing cuts
• 3/8-inch inscribed circle with 0.008-inch corner radius for precise edge geometry
• Clamp and pin insert holding method for secure seating in compatible toolholders
• Compliant with ISO 13399 tooling data standards for integration with CAM and tool management systems

Compatibility

Designed as an OEM-style replacement and standard production insert for WNMG-style toolholders accepting a 3/8-inch inscribed circle insert within the Isoturn series. Specific compatible toolholder model numbers were not provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and clamping screw specified by the toolholder manufacturer to seat the insert securely without over-torquing. Inspect the insert pocket and clamping hardware for wear or debris before seating a new insert.
