Sandvik Coromant 5741551 Cutoff Insert 1.5mm Corocut 3

Product Description

The SANDVIK COROMANT 5741551 is a solid carbide cutoff and grooving insert designed for parting and grooving operations on CNC lathes and turning centers. It belongs to the CoroCut 3 series and features a 1.5 mm cutting width with a right-hand lead angle of 10 degrees. The insert is manufactured in grade 1125 with a PVD-applied TiAlN coating, which provides wear resistance and thermal stability in demanding turning applications. The CS chipbreaker geometry promotes controlled chip formation during cutoff operations. This insert is installed by machinists and CNC turning specialists in production and job-shop environments.

The 5741551 is intended for cutoff and grooving applications on bar stock and turned components in both production and precision machining settings. The CoroCut 3 platform uses a clamp-style insert holding method with an R123T3 insert style and T-size insert seat, suited for narrow-groove and parting work. The 10-degree right-hand lead angle assists in directing cutting forces for stable, clean separation cuts. This insert is applicable to a broad range of workpiece materials where PVD-coated carbide tooling is appropriate.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret is in a safe index position before changing inserts. Use the appropriate torque wrench and clamping screw specified for the CoroCut 3 toolholder to secure the insert without over-torquing. Inspect the insert seat and clamp for debris or damage before seating the new insert.
