Iscar 5509913 CNMG432PP IC6025 Turning Insert Carbide

Product Description

The ISCAR 5509913 is a CNMG432PP-geometry turning insert in grade IC6025, designed for external and internal turning operations on CNC lathes and turning centers. The insert is manufactured from solid carbide and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability at elevated cutting speeds. The 80-degree diamond shape (CNMG) with a neutral 0-degree relief angle delivers strong cutting edge geometry suited for medium to roughing cuts. The PP chip breaker geometry controls chip flow across a wide range of feeds and depths, reducing the risk of chip packing in confined bores or tight workholding setups. This insert is installed by machinists and CNC operators in production and job-shop environments.

The 5509913 belongs to ISCARs Isoturn series and is intended for turning applications on stainless steel and other ISO M workpiece materials, including austenitic and ferritic grades. Its IC6025 substrate and CVD coating make it well suited for continuous and semi-interrupted cuts where edge stability and crater resistance are priorities. A maximum depth of cut of 4.00 mm (0.1575 inches) positions this insert for medium finishing to moderate roughing passes. The 1/32-inch corner radius minimizes corner stress while maintaining surface finish control.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for wear and thermal resistance
• 80-degree diamond insert shape (CNMG) with 0-degree relief angle for robust edge strength
• PP chip breaker for controlled chip formation across varied feed rates
• Maximum depth of cut of 4.00 mm (0.1575 inches)
• Clamp and pin holding method compatible with standard CNMG toolholders
• Meets ISO 13399 tooling data standards

Compatibility

Designed as an OEM-style replacement or standard-stocking turning insert for CNMG-style toolholders that accept a 1/2-inch inscribed circle, 3/16-inch thick, 80-degree diamond insert with clamp and pin retention.

Installation Notes

Installation and indexing of turning inserts should be performed by a qualified machinist with the machine in a full stop, lockout-tagout condition. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer - do not over-torque the clamp, as this can fracture the carbide. Inspect the insert pocket for chips, burrs, or seat damage before seating a new insert. Verify insert orientation and chip breaker direction match the intended cutting geometry before resuming operation.
