Sandvik Coromant 5736617 Cutoff Insert 5mm Corocut 1-2

Product Description

The SANDVIK COROMANT 5736617 is a solid carbide cutoff insert designed for precision parting and grooving operations on CNC lathes and turning centers. Cataloged under manufacturer part number N123J2-0500-0004-CR 1145, this insert belongs to the CoroCut 1-2 series and features a 5 mm cutting width with a neutral lead angle and a 0-degree lead angle geometry. The CR chipbreaker geometry promotes controlled chip evacuation during cutoff. A PVD-applied TiAlN and AlCr2O3 coating provides thermal resistance and edge durability at elevated cutting speeds. Machinists and CNC operators working in production turning environments will find this insert suited to consistent, repeatable cutoff work in steel and similar materials.

This insert is applied in cutoff and grooving applications on bar stock, tubing, and turned components in both job shop and production settings. The CoroCut 1-2 series uses a clamp-style insert holding method, making this insert compatible with appropriately sized CoroCut 1-2 toolholders that accept the J insert seat size. It is typically installed by machinists and tool-and-die professionals working on CNC or manual turning equipment where controlled parting cuts are required.

Key Features

• Solid carbide substrate with manufacturer grade 1145 for consistent edge performance
• 5 mm cutting width (0.1969 inches) with a neutral hand and 0-degree lead angle
• PVD coating combining TiAlN and AlCr2O3 layers for thermal and wear resistance
• CR chipbreaker promotes chip control during parting and grooving operations
• Maximum depth of cut of 23.70 mm (0.9331 inches) suits a wide range of bar diameters
• 0.40 mm (0.0157 inches) corner radius provides a defined edge geometry at the cut
• Clamp-style insert holding in J-seat CoroCut 1-2 toolholders for secure seating

Compatibility

Designed for use with CoroCut 1-2 series toolholders that accept J insert seat size and are configured for 5 mm cutting width inserts. No additional specific compatible model numbers were provided in the product data.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist with the machine in a stopped and locked-out state. Use the appropriate torx or hex key as specified by the toolholder manufacturer when seating the clamp; do not overtighten. Verify insert seating and clamp engagement before resuming cutting operations. Consult the toolholder documentation for recommended clamping torque and runout tolerances specific to the holder in use.
