Sandvik Coromant 5741842 Cutoff Insert Solid Carbide 3mm

Product Description

The SANDVIK COROMANT 5741842 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Cataloged under the T-Max Q-Cut series with insert style R151.2 and manufacturer grade 235, this insert features a 3.00 mm (0.1181 inch) cutting width and a 12-degree right-hand lead angle. The CVD-applied TiCN/TiN coating provides wear resistance and thermal stability during high-speed cutoff work. A 5F chipbreaker geometry controls chip flow and reduces built-up edge in steel and similar materials. Machinists and CNC operators in production and job-shop environments install this insert as a direct OEM-catalog replacement.

This insert is suited for parting, grooving, and profiling on metal workpieces in both production and precision turning applications. The clamp-style insert holding method ensures secure seating in compatible T-Max Q-Cut toolholders. The right-hand insert orientation and 12-degree lead angle make it appropriate for standard right-hand turning setups. A 7-degree relief angle and a 0.0039-inch corner radius support clean, controlled cuts with minimal burring on the parted face.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and clamp screw specified for the T-Max Q-Cut toolholder to secure the insert — do not overtighten by hand estimation. Inspect the insert seat and clamp for chips or debris before seating the new insert to ensure proper contact and runout.
