Iscar 5505753 Vnmg Turning Insert IC907 Solid Carbide

Product Description

The ISCAR 5505753 is a VNMG-style solid carbide turning insert from the Isoturn series, designed for precision external and internal turning operations on CNC lathes and turning centers. Featuring a 35-degree diamond shape with a positive rake geometry and a neutral 0-degree relief angle (clearance code N), this insert is coated with TiAlN and TiN via a PVD process under the IC907 grade designation. The 1/32-inch corner radius and NF chip breaker geometry make it well suited for finishing passes on a range of workpiece materials. Licensed machinists and CNC operators working in production or job-shop environments will recognize the Isoturn platform as a dependable OEM-style format.

This insert targets turning applications across multiple ISO material groups, including steel, stainless steel, heat-resistant superalloys, cast iron, non-ferrous materials, and hardened materials (ISO codes H, K, M, N, P, S). It fits standard VNMG toolholders that accept a 9/32-inch inscribed circle and a 5/32-inch insert thickness. Typical applications include finish turning where tight tolerances and controlled chip formation are required. The NF chip breaker geometry supports near-net-shape finishing with low cutting forces.

Key Features

• IC907 grade with TiAlN and TiN PVD coating for wear resistance across multiple material groups
• 35-degree diamond insert shape (V) with positive rake for reduced cutting forces
• NF chip breaker geometry optimized for finishing operations
• 0.0315-inch (1/32-inch) corner radius for precision surface finish
• Clamp and pin insert holding method for secure seating in compatible toolholders
• Conforms to ISO 13399 standards for tooling data representation

Compatibility

Designed for use in VNMG-compatible toolholders accepting a 9/32-inch inscribed circle, 5/32-inch insert thickness, and standard M-tolerance, N-clearance insert geometry. Suitable for ISO material groups H, K, M, N, P, and S per the IC907 grade specification.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Before indexing or replacing inserts, shut down spindle rotation and confirm the machine is in a safe, locked-out state per shop safety procedures. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not over-tighten the clamp or pin, as this can cause insert fracture or seat damage. Inspect the insert pocket and seating surfaces for chips or debris before seating the new insert.
