Sandvik Coromant 5737989 Grooving Insert Solid Carbide

Product Description

The SANDVIK COROMANT 5737989 is a solid carbide grooving insert in the T-Max Q-Cut series, designed for precision external grooving and parting operations on CNC lathes and turning centers. It carries a TiAlN coating applied via PVD process, which provides thermal stability and wear resistance at elevated cutting speeds. The insert features a neutral hand orientation, a 0.094 inch (2.39 mm) cutting width, and a 4G chip breaker geometry. A corner radius of 0.007 inch (0.18 mm) supports consistent edge definition on grooved profiles. This insert is installed by machinists and CNC operators in production and job-shop turning environments.

This insert is suited for grooving and parting applications on ferrous and non-ferrous workpieces where tight groove width tolerances are required. The 4G chip breaker is optimized for controlled chip formation during radial feed operations. The neutral rake geometry and 11-degree rake angle make this insert appropriate for a range of materials at moderate to high cutting speeds. Its multi-use classification indicates it is compatible with multiple grooving toolholder body styles within the T-Max Q-Cut system. Install seat size 25 must be matched to the corresponding toolholder pocket.

Key Features

• Solid carbide substrate with PVD-applied TiAlN coating for thermal and abrasive wear resistance
• 0.094 inch cutting width with a 3/32 inch fractional equivalent for precise groove sizing
• 4G chip breaker geometry for controlled chip evacuation during radial grooving
• Neutral hand orientation and 11-degree rake angle for versatile material compatibility
• Corner radius of 0.007 inch (0.18 mm) for sharp, defined groove edges
• Multi-use tool classification within the T-Max Q-Cut system

Compatibility

Designed for use with T-Max Q-Cut series toolholders accepting insert seat size 25. ISO code N151.3-A094-25-4G 1125 and catalog number N151.3-A094-25-4G 1125 can be used to cross-reference compatible blade and holder bodies within the SANDVIK COROMANT T-Max Q-Cut product family.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The machine spindle must be stopped and all axis motion must be halted before inserting or replacing the grooving insert. Use the correct torque wrench and insert clamp hardware specified for the T-Max Q-Cut toolholder to avoid seat damage or insert fracture. Inspect the insert pocket and seating surface for chips or debris before installation.
