Iscar 5507537 SCMT3114 IC9150 Carbide Turning Insert

Product Description

The ISCAR 5507537 is a carbide turning insert in the SCMT3114 geometry, designed for single-point turning operations on CNC lathes and turning centers. It carries the IC9150 manufacturer grade and features a multilayer CVD coating of TiCN, Al2O3, and TiN, providing wear resistance and thermal stability during interrupted and continuous cuts. The insert has a 90-degree square shape with a 0.375-inch inscribed circle and a 0.0157-inch corner radius. It belongs to ISCAR's Isoturn series and is held in place by a screw-clamp method. Machinists and CNC operators working with cast iron and steel workpieces install this insert in compatible SCMT-style toolholders.

This insert is suited for turning cast iron and steel in both production and job-shop environments. The positive rake geometry reduces cutting forces and is appropriate for finishing and semi-finishing passes. A maximum depth of cut of 0.1378 inches supports controlled stock removal in ferrous materials. The Isoturn series is commonly used in industrial turning cells where insert indexability, consistent edge geometry, and predictable tool life are required.

Key Features

• IC9150 carbide grade with multilayer CVD coating: TiCN, Al2O3, and TiN for extended tool life in ferrous materials
• SCMT geometry with 90-degree square shape and positive rake for reduced cutting forces
• 0.0157-inch corner radius supports semi-finish and finish turning surface requirements
• Screw-clamp holding method provides secure seating and repeatable indexing
• Maximum depth of cut of 0.1378 inches suitable for semi-finishing passes on cast iron and steel
• ISO 13399 compliant tooling data for integration with CAM and tooling management systems

Compatibility

Designed for use in SCMT-style screw-clamp turning toolholders that accept a 0.375-inch inscribed circle square insert. Primary workpiece materials are cast iron (ISO material code K) and steel (ISO material code P).

Installation Notes

This insert is installed and indexed by a licensed machinist or CNC toolroom technician. Power down and lock out the machine spindle before changing or indexing inserts. Use the correct torque driver for the screw-clamp fastener to ensure proper seating without stripping the insert pocket. Inspect the toolholder pocket and clamp screw for wear or debris before installing a new insert edge.
