Iscar 5505158 DNMG332NF IC907 Turning Insert 3/8 in Ic

Product Description

The ISCAR 5505158 is a solid carbide turning insert in the DNMG332NF geometry, manufactured to ISO 13399 standards and assigned manufacturer grade IC907. The insert features a 55-degree diamond shape with a positive rake angle and NF chip breaker configuration, making it well suited for finishing operations on a range of workpiece materials. A PVD-applied TiAlN and TiN dual coating improves wear resistance and thermal stability during interrupted or continuous cuts. The insert measures 11.63 mm (0.4579 inches) in length, carries a 3/8-inch (0.3748-inch) inscribed circle, and has a 3/16-inch (0.1870-inch) thickness. Maximum depth of cut is 3.50 mm (0.1378 inches). It is held by clamp or pin and is sold individually with a minimum order quantity of 10.

This insert is designed for use in CNC and manual turning centers where precision finishing passes are required. The DNMG geometry suits external and profiling operations on components made from hardened steels, stainless steels, heat-resistant superalloys, and other materials falling within primary workpiece material codes H, K, M, N, P, and S. The Isoturn series designation indicates compatibility with ISCAR Isoturn toolholders accepting DNMG-style inserts. Machinists and tool-room operators in production, job-shop, and aerospace environments commonly specify this grade and geometry for its consistent edge life on demanding materials.

Key Features

• IC907 grade with PVD TiAlN and TiN coating for wear resistance on tough and heat-resistant alloys
• 55-degree diamond (DNMG) insert shape with positive rake for reduced cutting forces
• NF chip breaker geometry optimized for finishing cuts
• 3/8-inch inscribed circle with 1/32-inch (0.0315-inch) corner radius for precise profiling
• Clamp and pin holding method provides secure seating under interrupted-cut conditions
• Manufactured to ISO 13399 standard for consistent tooling data interchange

Compatibility

Designed for use with ISCAR Isoturn series toolholders accepting DNMG-style inserts. Suitable for turning workpiece materials classified under ISO material groups H, K, M, N, P, and S, corresponding to material grades C7 and C8.

Installation Notes

Installation is performed by a machinist or toolroom technician following the toolholder manufacturer's clamping torque and seating procedure. Power down and lock out the machine spindle before indexing or replacing inserts. Inspect the insert pocket and locating pin for debris or wear before seating a new insert to ensure proper contact and edge repeatability. Always verify insert orientation and chip breaker direction against the operation setup sheet before resuming cuts.
