Product Description

The SANDVIK COROMANT 5737391 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Carrying insert style N151.2 and manufacturer grade 1125, this insert features a 4.00 mm cutting width, a neutral lead angle, and a PVD-applied TiAlN coating that supports performance in a range of workpiece materials. The chipbreaker geometry is 5E and the corner radius measures 0.20 mm. At an overall length of 6.80 mm and an overall width of 4.00 mm, it is a compact insert held in place by a clamp-style insert seat. It belongs to the T-Max Q-Cut series and is intended for use by machinists and tooling specialists performing precision cutoff work.

This insert is suited for parting and groove-turning applications in production and job-shop environments operating CNC or manual lathes. The N151.2 insert style and size code 40 seat are characteristic of standard T-Max Q-Cut toolholders. The 1125 grade with TiAlN PVD coating makes it applicable across steel, stainless, and similar materials where a wear-resistant, heat-tolerant cutting edge is required. Minimum order quantity is 10 units; each package contains 1 insert.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Shut down and lock out the machine before seating or indexing any insert. Ensure the insert seat is clean and free of chips or debris before clamping, as contamination can cause insert rocking and premature edge failure. Follow the toolholder manufacturer's clamping torque specifications and consult applicable shop safety procedures when handling carbide inserts.
