The SANDVIK COROMANT 5737500 is a solid carbide grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. Part of the T-Max Q-Cut series, this insert carries the ISO designation N151.2-A125-30-4P 1125 and features a TiAlN coating applied via PVD process for extended tool life in abrasive and hard materials. The neutral hand orientation makes it suitable for both left- and right-hand toolholders. With a cutting width of 0.125 inches (3.17 mm) and a maximum depth of cut of 0.05 inches (1.27 mm), it is built for controlled, repeatable groove profiles in production environments. Licensed machinists and CNC operators in metalworking shops are the primary installers.
This insert is suited for grooving, parting, and profiling operations in ferrous and non-ferrous materials on production lathes and turning centers. The 4P chip breaker geometry promotes efficient chip evacuation in interrupted and continuous cuts. The insert fits insert seat size 30 toolholders compatible with the T-Max Q-Cut system. It is appropriate for high-volume production turning applications where consistent groove geometry and dimensional accuracy are required.
Designed for use with T-Max Q-Cut series toolholders accepting insert seat size 30. ISO code N151.2-A125-30-4P 1125. Confirm toolholder seat size and insert hand requirement before ordering.
Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the turret is locked before changing inserts. Use the correct torque wrench per toolholder manufacturer specifications when securing the clamping screw. Inspect the insert seat and clamping components for wear or debris before seating the new insert to maintain proper positioning and cutting geometry.
