Iscar 5509364 WNMG431PP IC6015 Turning Insert Isoturn

Product Description

The ISCAR 5509364 is a WNMG431PP IC6015 grade solid carbide turning insert engineered for precision metal cutting in CNC and manual lathe applications. The insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which delivers wear resistance, thermal barrier protection, and surface lubricity across a range of cutting conditions. With an 80-degree trigon (W) insert shape, a 0.5 inch inscribed circle, and a 1/64 inch corner radius, this insert is suited to medium-duty turning where edge sharpness and coating durability are priorities. It belongs to ISCARs Isoturn series and carries a PP chip breaker geometry. Licensed machinists, CNC operators, and toolroom technicians are the primary installers.

This insert is intended for turning stainless steel and other ISO M-category workpiece materials, including austenitic and ferritic stainless alloys where built-up edge and heat generation are common challenges. The IC6015 grade with its CVD multilayer coating is optimized for semi-finishing to medium roughing passes at moderate to high cutting speeds. The PP chip breaker geometry promotes controlled chip formation in these materials. The insert fits standard WNMG-style toolholders that accept clamp and pin holding methods, making it compatible with a broad range of turret and gang tool setups on production and job-shop lathes.

Key Features

• CVD multilayer coating: TiCN base, Al2O3 thermal layer, TiN outer layer for wear resistance and heat management
• IC6015 carbide grade optimized for ISO M stainless steel and similar difficult-to-machine materials
• 80-degree trigon insert shape (WNMG) with 0 degrees relief angle (N clearance) for rigid, stable cutting
• PP chip breaker geometry for controlled chip evacuation in semi-finishing and medium roughing
• 1/64 inch corner radius suited to moderate feed rates with acceptable surface finish
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems

Compatibility

Designed as a direct-fit replacement insert for WNMG431 toolholders using clamp and pin clamping methods within the ISCAR Isoturn series. Specific toolholder compatibility should be confirmed against ISCAR Isoturn toolholder documentation for the WNMG insert style.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician with the machine in a full stop, spindle off, and axis motion disabled before any insert change. Inspect the toolholder pocket and seating surface for chips or damage before seating the insert. Use the appropriate torque wrench and clamping screw specified by the toolholder manufacturer — do not overtighten, as this can fracture the carbide. Verify insert seating and clamp engagement before resuming cutting operations.
