Sandvik Coromant 5737381 Cutoff Insert 4mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5737381 is a solid carbide cutoff insert engineered for parting and grooving operations on CNC lathes and turning centers. Carrying insert style designation N151.2-400-7E in grade 1125, this insert features a 4 mm cutting width, a neutral lead angle, and a 7-degree relief angle. The PVD-applied TiAlN coating provides thermal and wear resistance suited to a broad range of workpiece materials. The 7E chipbreaker geometry promotes controlled chip formation and evacuation during deep parting cuts. Licensed machinists and CNC operators working in production or job-shop environments will find this insert a direct fit for compatible T-Max Q-Cut toolholders and blade systems.

This insert is designed for use in the T-Max Q-Cut series parting and grooving system, which is common in residential and commercial machine shops as well as production turning cells. It handles parting, face grooving, and light profiling on bar stock and chucked workpieces. The neutral hand designation makes it suitable for both conventional and swiss-style turning setups where a centered cutting edge is required. The 0.15 mm corner radius reduces edge stress on entry and supports clean surface finish at the parting face. Minimum order quantity is 10 inserts; each package contains 1 insert.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the clamp pocket and verify the clamp screw torque per the toolholder manufacturer specification before resuming cutting. Inspect the insert seat and clamping surfaces for chips or debris prior to seating a new insert to ensure proper edge height and alignment.
