Iscar 5507726 CNMA432 IC5005 Carbide Turning Insert

Product Description

The ISCAR 5507726 is a CNMA432 solid carbide turning insert in the IC5005 manufacturer grade, designed for precision external and internal turning operations on CNC lathes and turning centers. The insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides thermal resistance and wear protection during high-speed cutting. With an 80-degree diamond shape, a 0 degree relief angle (clearance code N), and tolerance code M, this insert is engineered for stable, repeatable cuts on hard and abrasive workpiece materials. It is installed by machinists and tooling technicians using a clamp and pin holding method.

This insert is suited for turning operations on cast iron (ISO K), hardened steels (ISO H), and steel (ISO P) workpiece material groups. The Isoturn series is commonly used in production turning environments where consistent chip control and tool life are critical. The chip breaker code A and maximum depth of cut of 0.157 inches make this insert appropriate for moderate to finishing-pass material removal rates in shop and production floor settings.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for thermal and abrasion resistance
• 80-degree diamond insert shape (CNMA style) for versatile turning geometry
• IC5005 grade optimized for ISO H, K, and P primary workpiece material groups
• Clamp and pin holding method for secure, repeatable seating in compatible toolholders
• ISO 13399 compliant tooling data standard for integration with CAM and tool management systems
• Maximum depth of cut of 0.157 inches (4.00 mm) suitable for finishing and light roughing passes

Compatibility

Designed as an OEM-style replacement or direct-fit insert for CNMA432 toolholders accepting a 0.500-inch inscribed circle, 80-degree diamond insert with a clamp and pin holding method, conforming to ISO CNMA120408 geometry.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or indexing the insert. Ensure the toolholder pocket and seating surfaces are clean and free of chips or debris before clamping. Verify clamp and pin torque specifications per the toolholder manufacturer guidelines, and confirm insert seating is flush before resuming cutting operations.
