Iscar 5590529 Dnmg 442-TF IC907 Turning Insert Isoturn

Product Description

The ISCAR 5590529 is a DNMG 442-TF solid carbide turning insert finished with a TiAlN and TiN PVD coating in the IC907 manufacturer grade. It features a 55-degree diamond insert shape (Shape Code D) with a 0.5 inch inscribed circle, a 0.25 inch insert thickness, and a 1/32 inch (0.0315 inch) corner radius. The TF chip breaker geometry and positive rake angle promote efficient chip evacuation and reduced cutting forces. Licensed machinists and CNC turning technicians install this insert in indexable toolholders for precision external turning operations on a range of workpiece materials.

This insert is suited for turning applications on workpiece materials classified under ISO material groups H, K, M, N, P, and S, covering hardened steels, cast irons, general steels, non-ferrous alloys, standard steels, and heat-resistant superalloys. It is part of the Isoturn series, designed for external turning on CNC lathes in both production and job-shop environments. The clamp and pin insert holding method secures the insert firmly under the varied cutting loads common in interrupted or continuous turning passes. Maximum depth of cut is 3.50 mm (0.138 inch).

Key Features

• IC907 grade solid carbide substrate with TiAlN and TiN PVD coating for extended tool life in tough materials
• 55-degree diamond insert shape with DNMG style for positive-rake, free-cutting performance
• TF chip breaker geometry optimized for chip control across a broad range of ISO material groups
• Clamp and pin holding method for secure, repeatable seating in compatible toolholders
• Maximum depth of cut of 3.50 mm (0.138 inch) for reliable stock removal on finishing and semi-finishing passes
• PVD coating process preserves sharp edge geometry and improves surface finish on workpiece

Compatibility

Designed for use in DNMG-style indexable turning toolholders that accept inserts with a 0.5 inch inscribed circle, 0.25 inch thickness, and clamp or pin holding. Compatible with workpiece materials in ISO groups H, K, M, N, P, and S. Conforms to ISO 13399 standards for cutting tool data representation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully and evenly against the toolholder pocket before tightening the clamp or pin to prevent insert rocking or chatter during the cut. Inspect the insert pocket for debris, wear, or damage before each insert change to maintain dimensional accuracy and surface finish consistency.
