Sandvik Coromant 5736260 Cutoff Insert 3mm Corocut 1-2

Product Description

The SANDVIK COROMANT 5736260 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Manufactured to the N123G1-0300-0002-CM 1125 specification, it features a 3 mm cutting width and a neutral lead angle suited for straight, axial parting cuts. The CM chipbreaker geometry controls chip formation across a range of materials. Applied with a PVD-deposited TiAlN coating and manufactured in grade 1125, this insert delivers consistent wear resistance in both interrupted and continuous cutting conditions. It is installed by machinists and CNC lathe operators on compatible CoroCut 1-2 toolholders using a clamp-style holding method.

This insert is intended for use in the CoroCut 1-2 series toolholding system, designed for parting and grooving in turning applications on both manual and CNC lathes. The neutral hand orientation makes it suitable for standard right-hand parting setups. The G insert seat size and 19.94 mm overall length position it for medium-range workpiece diameters in production and job-shop environments. Machinists working with steel, stainless, and coated alloy materials will find the 1125 grade appropriate for a broad range of cutting conditions.

Installation Notes

Installation should be performed by a qualified machinist with the machine fully powered down and the spindle locked before insert exchange. Use the appropriate Torx or hex key as specified by the toolholder manufacturer to secure the clamp; do not overtighten. Inspect the insert pocket and clamp for chips or debris before seating the insert. Confirm cutting width and seat size match the toolholder specification before beginning a cut.
