Iscar 5509369 DNMG432TF IC6015 Turning Insert Isoturn

Product Description

The ISCAR 5509369 is a DNMG432TF indexable turning insert manufactured in the IC6015 grade solid carbide with a multilayer CVD coating of TiCN, Al2O3, and TiN. It belongs to the Isoturn series and is designed for external and internal turning operations on CNC lathes and turning centers. The insert measures 15.5 mm (0.6102 inches) in length with a 1/2-inch inscribed circle and a 1/32-inch corner radius. The TF chip breaker geometry promotes positive rake cutting action, helping control chip flow during medium to finishing passes. Installation is performed by licensed machinists and tooling specialists using standard clamp and pin holding methods.

This insert is suited for machining ISO material group M workpieces, which includes stainless steels and similar materials. The 55-degree diamond shape (D insert style) and N clearance code make it appropriate for profiling and longitudinal turning where access to workpiece geometry is a priority. A maximum depth of cut of 3.50 mm (0.138 inches) positions this insert in medium finishing to light roughing applications. It is a single-insert package sold in minimum order quantities of 10 units, making it practical for production tooling rooms and job shops maintaining indexable tooling inventory.

Key Features

• IC6015 grade solid carbide with multilayer CVD coating: TiCN, Al2O3, and TiN for wear and crater resistance
• DNMG insert style with 55-degree diamond shape for profiling and turning access
• TF chip breaker promotes positive rake cutting and chip control in medium to finish cuts
• 1/32-inch corner radius for moderate edge strength and surface finish performance
• Clamp and pin holding method for secure seating in DNMG-compatible toolholders
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed as an OEM-style indexable replacement for DNMG432 turning inserts in toolholders accepting the DNMG insert style with clamp and pin holding. Verify toolholder pocket geometry and insert seat dimensions before installation.

Installation Notes

Turning inserts of this type are installed and indexed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing or indexing any insert. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten the clamping screw, as this can fracture the insert. Inspect the insert pocket and locating pin for wear or debris before seating a new insert edge.
