Sandvik Coromant 5737937 Grooving Insert 0.142in Tialn

Product Description

The SANDVIK COROMANT 5737937 is a solid carbide grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Finished with a PVD-applied TiAlN coating, this insert delivers thermal resistance and edge durability in demanding cutting conditions. It carries a 0.142 inch cutting width and a 0.208 inch cutting height, making it suitable for shallow to medium-depth grooving profiles. The insert belongs to the T-Max Q-Cut series and features a 4G chip breaker geometry. It is installed by CNC machinists and tool-room technicians working in production or job-shop environments.

This insert is intended for grooving and cut-off applications on metal workpieces including steel, stainless steel, and similar materials where a TiAlN-coated carbide grade performs reliably. The neutral hand orientation makes it compatible with standard straight-shank and cartridge-style toolholders designed for the T-Max Q-Cut system. The manufacturer grade is 1125, and the ISO catalog designation is N151.3-A142-30-4G 1125. Insert seat size is 30. This insert suits both high-volume production turning and maintenance tooling requirements.

Compatibility

Designed for use with T-Max Q-Cut series toolholders accepting insert seat size 30. ISO code N151.3-A142-30-4G 1125 identifies the exact toolholder and seat configuration required. Consult the SANDVIK COROMANT T-Max Q-Cut toolholder catalog to confirm seat and clamping compatibility before installation.

Installation Notes

This insert is installed by qualified machinists or toolroom technicians. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and clamping screw specified for the T-Max Q-Cut toolholder to seat the insert correctly — do not overtighten or substitute fasteners. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert.
