Sandvik Coromant 5741544 Cutoff Insert 1.5mm Corocut 3

Product Description

The SANDVIK COROMANT 5741544 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Part of the CoroCut 3 series, it features a 1.5 mm cutting width and a right-hand lead angle of 5 degrees, making it suited for precise, narrow-groove parting on bar stock and turned components. The insert uses a TiAlN PVD coating applied over a 1125 grade carbide substrate, providing wear resistance and thermal stability at elevated cutting speeds. It is clamped into compatible CoroCut 3 toolholders and is installed by machinists and CNC tooling technicians in production and job-shop environments.

This insert is intended for use in metal-cutting applications where clean parting, shallow grooving, or profiling is required. The CS chipbreaker geometry is optimized for controlled chip formation in a range of workpiece materials. With a maximum depth of cut of 6.30 mm and an overall length of 10.72 mm, this insert fits standard CoroCut 3 insert seats sized T. It is appropriate for both high-volume production turning and precision part work where groove width accuracy is critical.

Key Features

• 1.5 mm cutting width for narrow parting and grooving operations
• Solid carbide construction with TiAlN PVD coating for extended tool life
• Manufacturer grade 1125 substrate designed for balanced wear resistance and toughness
• CS chipbreaker geometry for controlled chip evacuation
• 5-degree right-hand lead angle for directional cutting stability
• Maximum depth of cut of 6.30 mm suits most bar parting applications

Compatibility

Designed for use with CoroCut 3 series toolholders accepting insert style R123T3 with an insert seat size T. The manufacturers catalog number for this insert is R123T3-0150-0500-CS 1125.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Before changing inserts, power down the machine and confirm the spindle is fully stopped. Use the appropriate torque wrench and clamping hardware specified for the CoroCut 3 toolholder to seat the insert correctly — do not overtighten the clamp screw by feel alone. Inspect the insert seat for chips or debris before seating a new insert to ensure proper support and repeatable cutting geometry.
