Sandvik Coromant 5736406 Corocut 3 Cutoff Insert 1.5mm

Product Description

The SANDVIK COROMANT 5736406 is a solid carbide cutoff insert in the CoroCut 3 series, designed for parting and grooving operations on CNC lathes and turning centers. The insert features a 1.5 mm cutting width, a neutral lead angle, and a TiAlN coating applied via PVD process for extended wear resistance at elevated cutting temperatures. The CM chipbreaker geometry promotes controlled chip formation and efficient evacuation in a range of workpiece materials. Machining professionals and tool crib personnel will recognize this insert as a direct fit for CoroCut 3 toolholding systems.

This insert is suited for parting-off and slot grooving applications in production turning environments, including both light and medium-duty operations on ferrous and non-ferrous materials. The 0.10 mm corner radius and 7-degree relief angle make it appropriate for precision grooving where tight dimensional tolerances and clean surface finish are required. It is used in job shops, aerospace, automotive, and general machining facilities running CoroCut 3 compatible toolholders.

Key Features

• Solid carbide construction with grade 1125 for consistent edge integrity under thermal and mechanical load
• TiAlN PVD coating provides heat resistance and extended tool life
• 1.5 mm cutting width with neutral hand for flexible toolholder orientation
• CM chipbreaker geometry for reliable chip control in grooving and cutoff operations
• Maximum depth of cut of 6.40 mm (0.252 inches) for parting and deep grooving
• 0.10 mm corner radius for precision groove profiling

Compatibility

Designed for use with CoroCut 3 series toolholding systems using insert seat size T and clamp-style insert holding. Insert style is N123T3 as designated by the manufacturer catalog number N123T3-0150-0001-CM 1125.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians familiar with indexable insert toolholding systems. Ensure the machine spindle is fully stopped and the toolholder is secure before seating or replacing the insert. Use the appropriate torx or clamping key specified for the CoroCut 3 toolholder to avoid over-torquing the clamp. Inspect the insert seat and clamp for wear or debris before installing a new insert.
