Iscar 5591352 Wnmg Turning Insert Tialn Solid Carbide

Product Description

The ISCAR 5591352 is a solid carbide turning insert in the WNMG style, coated with TiAlN via a PVD process for wear resistance and extended tool life in demanding cutting operations. It features an 80-degree trigon insert shape, a 3/8-inch (0.3748 inch) inscribed circle, and a corner radius of 0.0039 inches. The insert measures 6.52 mm (0.2567 inches) in length and 0.1560 inches thick. With a positive rake geometry and NF chip breaker, it is engineered for controlled chip formation and stable cutting performance. It belongs to the ISCAR Isoturn series and conforms to ISO 13399 standards. Licensed machinists and CNC lathe operators install this insert in toolholders designed for WNMG-style inserts.

This insert is rated for universal primary workpiece material compatibility, covering material groups H, K, M, P, and S per ISO designation. That range includes steel, stainless steel, cast iron, non-ferrous alloys, and heat-resistant superalloys. The NF chip breaker geometry is suited for finishing passes where tight chip control and surface finish consistency are priorities. Maximum depth of cut is 1.00 mm (0.0394 inches). It is held in the toolholder via clamp and pin retention, which is standard for WNMG-configuration boring and turning applications on CNC lathes and turning centers in both job-shop and production environments.

Key Features

• TiAlN coating applied via PVD process for thermal stability and extended cutting life
• 80-degree trigon (W) insert shape with WNMG style designation
• NF chip breaker for controlled chip evacuation during finishing operations
• Positive rake geometry reduces cutting forces on workpiece and toolholder
• Clamp and pin holding method for secure, repeatable seating in compatible toolholders
• Conforms to ISO 13399 tooling data standards for system integration

Compatibility

Designed for use in WNMG-style toolholders from the ISCAR Isoturn series. Compatible with workpiece material groups H, K, M, P, and S as defined by ISO material classification. Verify toolholder insert pocket geometry, clearance code N, and tolerance code M compliance before installation.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians familiar with indexable insert tooling. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the insert pocket and seating surface are clean and free of chips or debris before clamping. Torque the clamp and pin to the toolholder manufacturer's specification — do not over-tighten, as carbide inserts are brittle and susceptible to fracture under uneven clamping load.
