Iscar 5507737 WNMA432 IC5010 Turning Insert Solid Carbide

Product Description

The ISCAR 5507737 is a solid carbide turning insert designed for external and internal turning operations on CNC and manual lathes. Manufactured to WNMA432 geometry with an 80-degree trigon insert shape, it carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN under the IC5010 grade designation. The insert measures 8.70 mm (0.3425 inches) in length with a 1/2-inch inscribed circle and a 1/32-inch (0.0315 inches) corner radius. It belongs to the Isoturn series and is installed by machinists and toolroom technicians working in production turning environments where consistent tool life on hard materials is required.

This insert is rated for primary use on cast iron workpieces, corresponding to ISO material group K. It is suited for stable turning cuts at moderate-to-aggressive feed rates where the multilayer CVD coating provides wear and crater resistance. The A chip breaker geometry supports controlled chip formation during continuous turning passes. Maximum depth of cut is 4.00 mm (0.1575 inches). This insert fits applications in automotive, heavy equipment, and general machining shops running cast iron components on standard or high-pressure coolant turning centers.

Key Features

• CVD-applied TiCN/Al2O3/TiN multilayer coating for wear resistance on cast iron
• IC5010 carbide grade optimized for ISO K material group cutting conditions
• 80-degree trigon (WNMA) insert shape with clamp and pin holding method
• 1/32-inch corner radius for general-purpose finishing and semi-finishing passes
• Maximum depth of cut of 4.00 mm (0.1575 inches) for stable material removal
• Compliant with ISO 13399 tooling data standards for CAM and tool management integration

Compatibility

Designed as an OEM-style replacement turning insert for Isoturn series toolholders accepting WNMA432 insert geometry with clamp and pin holding method.

Installation Notes

Turning inserts are installed and indexed by qualified machinists or CNC toolroom technicians. Power down and lock out the machine spindle before seating or replacing inserts. Secure the insert using the appropriate clamp and pin torque driver per the toolholder manufacturer specifications. Inspect the pocket seating surface for chips or debris before installation to ensure proper insert contact and prevent premature edge failure.
