Iscar 5550515 WNMG31NF IC807 Turning Insert Solid Carbide

Product Description

The ISCAR 5550515 is a WNMG31NF IC807 grade solid carbide turning insert designed for external and internal turning operations on CNC lathes and turning centers. Coated with TiAlN via a PVD process, the IC807 grade delivers thermal resistance and wear performance across a broad range of workpiece materials. The insert features an 80-degree trigon (W) shape with a neutral 0-degree relief angle (clearance code N) and a 1/64 inch corner radius. Insert length is 6.52 mm (0.2567 inches) with a 3/8 inch inscribed circle and a 5/32 inch insert thickness. The NF chip breaker geometry supports a positive rake configuration. This insert is installed by machinists and CNC operators in production and job-shop turning environments.

The ISCAR 5550515 WNMG31NF IC807 insert is suited for universal material applications, carrying primary workpiece material codes H, K, M, P, and S — covering steel, stainless steel, cast iron, non-ferrous materials, and high-temperature alloys. It belongs to the Isoturn series and is intended for finishing to light roughing passes. Maximum depth of cut is 2.50 mm (0.0984 inches). This insert fits toolholders designed for the WNMG insert style and is held by clamp and pin methods, consistent with standard ISO 13399 tooling systems.

• 1/64 inch corner radius suited for tight shoulder transitions and surface finish requirements
• Maximum depth of cut of 2.50 mm (0.0984 inches)
• Compliant with ISO 13399 tooling data standards

Compatibility

Designed as an OEM-style replacement turning insert for toolholders accepting the WNMG insert style with clamp and pin holding methods, per ISO 13399 specifications. No specific compatible model numbers were provided in the product data.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not overtighten the clamp screw. Inspect the toolholder seat for wear or debris before seating a new insert to ensure proper contact and edge geometry.
