Iscar 5505285 Vnmg 331 Nf IC907 Turning Insert Tialn

Product Description

The ISCAR 5505285 is a solid carbide turning insert in the VNMG 331 NF geometry, designed for precision external and internal turning operations on CNC lathes and turning centers. Manufactured to ISO 13399 standards, it carries an IC907 grade designation and a PVD-applied TiAlN coating for elevated heat resistance and wear performance. The insert features a 35-degree diamond shape with a positive rake angle and NF chip breaker geometry, suited for finishing and near-finishing passes. Insert length is 0.6535 inches (16.60 mm) with a 3/8-inch inscribed circle. Installation is performed by licensed machinists and CNC tooling specialists.

This insert belongs to the ISCAR Isoturn series and is engineered for turning applications across a broad range of workpiece materials. Primary workpiece material codes include H, K, M, N, P, and S, covering hardened steels, cast irons, general steels, non-ferrous metals, stainless steels, and high-temperature alloys. The NF chip breaker is optimized for light to medium feeds and fine surface finish requirements. The clamp-and-pin holding method provides secure seating in compatible toolholders during high-speed turning operations.

Key Features

• IC907 grade with PVD TiAlN coating for heat and wear resistance in demanding turning applications
• 35-degree diamond insert shape (VNMG) with positive rake for reduced cutting forces
• NF chip breaker geometry suited for finishing passes and fine surface finishes
• 3/8-inch inscribed circle with 1/64-inch corner radius for controlled edge geometry
• Compatible with clamp and pin holding systems per ISO 13399 specification
• Maximum depth of cut of 0.0980 inches for light to medium material removal

Compatibility

Designed as an OEM-style replacement for VNMG 331 NF geometry turning inserts in compatible ISCAR Isoturn series toolholders that accept clamp and pin insert holding. Verify toolholder seat geometry, clearance code N, and tolerance code M requirements before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before seating or replacing any insert. Inspect the toolholder pocket and clamp components for wear or debris before installing. Do not exceed the maximum depth of cut specification listed for this insert geometry.
