Sandvik Coromant 5738359 Cutoff Insert 5mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5738359 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Manufactured under the T-Max Q-Cut series, this insert features a 5.00 mm cutting width, a neutral lead angle, and a PVD-applied TiAlN plus AlCr2O3 coating for extended tool life under demanding cutting conditions. The insert style is N151.2 with a 4E chipbreaker geometry and a 0.40 mm corner radius. It is installed by machinists and CNC operators using a clamp-style insert holding method, making seating and replacement straightforward during production runs.

This insert is suited for precision cutoff and groove-turning applications in both production and job-shop environments. The neutral hand orientation and zero-degree lead angle make it appropriate for straight parting operations on a range of workpiece materials. The 1145 manufacturer grade combined with the PVD TiAlN plus AlCr2O3 coating provides thermal resistance and wear protection. Insert seat size is 50, corresponding to standard T-Max Q-Cut toolholders in the N151.2 system. This product is sold individually but requires a minimum order quantity of 10 units per purchase.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and SANDVIK COROMANT clamping hardware specified for T-Max Q-Cut toolholders — do not substitute fasteners. Inspect the insert seat for debris or damage before seating the new insert to ensure proper clamping force and runout.
