Iscar 5507865 Cnmg 431TF IC807 Carbide Turning Insert

Product Description

The ISCAR 5507865 is a CNMG 431TF indexable turning insert manufactured from solid carbide and coated with TiAlN via a PVD process. It belongs to ISCAR's Isoturn series and is designed for external and internal turning operations on CNC lathes and turning centers. The insert measures 12.9 mm (0.5079 inches) in length with a 1/2-inch (0.5000-inch) inscribed circle and a 1/64-inch (0.0157-inch) corner radius. The 80-degree diamond shape (C code) with a neutral 0-degree relief angle and positive rake geometry suits a range of metal-cutting applications. The IC807 grade TiAlN coating provides wear resistance at elevated cutting temperatures. Qualified tooling technicians and CNC machinists install and index these inserts as part of regular tool maintenance.

This insert is suited for turning operations across multiple workpiece material groups. Per the supplier's primary workpiece material codes, it is rated for use with hardened materials (H), cast iron (K), stainless steel (M), carbon and alloy steels (P), and superalloys and titanium (S). The TF chip breaker geometry is designed to control chip formation across these material groups. Maximum depth of cut is 4.00 mm (0.1575 inches). Typical applications include roughing and semi-finishing passes on turned components in aerospace, general machining, and heavy industrial production environments.

Key Features

Compatibility

Designed as an OEM-style indexable insert for CNMG-style turning toolholders that accept 431-size inserts with clamp and pin holding. Compatible workpiece material groups per supplier data: H, K, M, P, and S as defined by ISO material classification. Verify toolholder seat geometry and clamping pocket dimensions before installation.

Installation Notes

Indexable turning inserts of this type are installed and replaced by CNC machinists or tooling technicians during scheduled tool changes or after edge wear is detected. Power down and lock out the machine spindle before accessing the turret or toolholder. Use the appropriate Torx or hex key for the clamping screw and inspect the insert seat and clamp for debris or damage before seating a new insert. Do not exceed the recommended depth of cut for the insert size and material being machined.
