Iscar 5508273 WNMG431PP IC807 Turning Insert Isoturn

Product Description

The ISCAR 5508273 is a WNMG431PP trigon turning insert in the IC807 grade, designed for indexable tool holders used in CNC and manual turning operations. The insert is manufactured from solid carbide and features a TiAlN coating applied via PVD process, providing heat resistance and extended tool life when cutting a range of workpiece materials. Key dimensions include a 1/2 inch inscribed circle, a 3/16 inch insert thickness, and an 8.70 mm insert length. The PP chip breaker geometry and positive rake angle promote controlled chip flow and reduced cutting forces. Installation is performed by qualified machinists and toolroom technicians.

This insert is suited for turning applications across multiple material groups, including ISO material codes M, P, and S, covering stainless steels, carbon and alloy steels, and high-temperature alloys. The WNMG431PP geometry with a 1/64 inch corner radius and 80-degree trigon shape makes it appropriate for medium finishing and semi-finishing passes. It fits into WNMG-compatible insert pockets and is held in place by a clamp and pin method. The Isoturn series designation aligns this insert with ISCAR standard turning toolholders designed for that insert family.

Key Features

• IC807 grade solid carbide with PVD TiAlN coating for thermal stability and wear resistance
• PP chip breaker geometry with positive rake for efficient chip control and lower cutting forces
• 1/64 inch corner radius suited for medium finishing and semi-finishing operations
• Compatible with ISO M, P, and S workpiece material groups
• Clamp and pin insert holding method for secure seating in the toolholder pocket
• Conforms to ISO 13399 standard for cutting tool data representation

Compatibility

Designed as a direct-fit replacement for WNMG431PP insert pockets within the ISCAR Isoturn series toolholder system. Suitable for use in any WNMG-style pocket toolholder accepting a 1/2 inch inscribed circle trigon insert with clamp and pin retention.

Installation Notes

This insert is installed by qualified machinists or toolroom personnel. Always disengage the machine and bring the spindle to a full stop before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer to secure the insert. Inspect the pocket seat and clamp for debris or wear before seating a new insert to ensure proper contact and runout.
