Sandvik Coromant 5741489 Cutoff Insert 2.5mm Corocut 1-2

Product Description

The SANDVIK COROMANT 5741489 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries manufacturer part number R123F2-0250-0501-CF 2135 and belongs to the CoroCut 1-2 series. The insert features a 2.5 mm cutting width, a 5-degree right-hand lead angle, and a 7-degree relief angle. The TiCN/Al2O3/TiN multilayer coating is applied via MTCVD, providing wear resistance and thermal stability during high-speed parting cuts. The CF chipbreaker geometry supports chip control in a range of material types. Licensed machinists and CNC operators install this insert as a direct replacement in compatible CoroCut 1-2 toolholders.

This insert is suited for parting, grooving, and cutoff work on turned components in production and job-shop environments. The right-hand orientation and F seat size make it compatible with CoroCut 1-2 system toolholders configured for that insert seat. Maximum depth of cut is 18.40 mm, making it appropriate for moderate-diameter workpieces. The 0.15 mm corner radius helps reduce notch wear at the cutting edge while maintaining part surface finish at the groove or cutoff face.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine in a full stop and lockout state before insert change. Use the correct clamping screw torque as specified in the toolholder documentation supplied by SANDVIK COROMANT. Inspect the insert seat and clamping surfaces for debris or damage before seating the insert. Do not force the insert into the seat, as improper seating can cause premature edge failure or workpiece damage.
