Sandvik Coromant 5736312 Cutoff Insert 3mm Corocut 1-2

Product Description

The SANDVIK COROMANT 5736312 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Carrying manufacturer grade 2135 with a TiCN/Al2O3/TiN coating applied via MTCVD process, this insert delivers wear resistance and thermal stability in demanding production environments. The cutting width is 3.00 mm (0.1181 inches), the lead angle is neutral, and the relief angle is 7 degrees. The CR chipbreaker geometry controls chip flow during cutoff operations. This insert is installed by machinists and CNC lathe operators in production shops and toolrooms.

The 5736312 belongs to the CoroCut 1-2 series and is suited for cutoff and grooving applications on a wide range of workpiece materials in both light and general-purpose turning setups. The clamp-style insert holding method provides secure seating in compatible CoroCut 1-2 toolholders. The neutral hand orientation and neutral lead angle make it adaptable across standard parting applications. A corner radius of 0.30 mm (0.0118 inches) and an overall insert length of 19.75 mm (0.7776 inches) are consistent with precision parting work on small to medium diameter workpieces.

Installation Notes

This insert is installed by a qualified machinist or CNC toolsetter. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and clamp hardware specified for the CoroCut 1-2 toolholder to seat the insert securely — do not overtighten the clamp screw by feel alone. Inspect the insert pocket for chips or debris before seating a new insert to prevent premature edge failure.
