Sandvik Coromant 5737751 Grooving Insert Solid Carbide

Product Description

The SANDVIK COROMANT 5737751 is a solid carbide grooving insert from the T-Max Q-Cut series, designed for precision grooving and parting operations on CNC lathes and turning centers. This insert carries a TiAlN coating applied via PVD process, which provides heat resistance and extended tool life in demanding cutting conditions. The neutral hand orientation and 7G chip breaker geometry make it suitable for a wide range of workpiece materials and groove profiles. Key dimensions include a 0.1969 inch cutting width, a 0.2404 inch cutting height, and a 0.0157 inch corner radius. It is installed by machinists and tool-room technicians working in metalworking and precision machining environments.

This insert is used in grooving and cut-off applications on metal workpieces in both production and job-shop turning operations. The N151.3 insert style seats into compatible T-Max Q-Cut toolholders. It is suited for external grooving where consistent groove width and surface finish are required. The 7G chip breaker geometry supports controlled chip evacuation during moderate-depth grooving passes. Insert size 40 and seat size 40 are consistent across the T-Max Q-Cut toolholder family. The ISO code for this insert is N151.3-500-40-7G 1125, which can be used to cross-reference compatible holders and alternatives in the SANDVIK COROMANT catalog.

Key Features

• Solid carbide substrate with PVD TiAlN coating for heat and wear resistance
• 0.1969 inch (5.00 mm) cutting width for precise groove sizing
• 7G chip breaker geometry for controlled chip formation during grooving
• Neutral hand orientation — compatible with both left- and right-hand setups where toolholder allows
• 0.0157 inch (0.40 mm) corner radius reduces stress concentration at groove edges
• Multi-use tool design supports grooving, profiling, and parting applications

Compatibility

This insert is designed for use with SANDVIK COROMANT T-Max Q-Cut toolholders that accept the N151.3 insert style with insert seat size 40. The ISO designation N151.3-500-40-7G 1125 should be used to confirm holder compatibility. No additional compatible model numbers were specified in the product data.

Installation Notes

Grooving inserts of this type are seated and clamped by qualified machinists following the toolholder manufacturer's torque and clamping procedures. Ensure the machine spindle is fully stopped and the machine is in a safe state before changing inserts. Handle carbide inserts with care — edges are sharp and the substrate is brittle. Verify insert seating and clamping security before resuming cutting operations.
