Sandvik Coromant 5753157 Grooving Insert TLGP2 1125 Solid Carbide

Product Description

The SANDVIK COROMANT 5753157 is a solid carbide grooving insert designed for precision external grooving and turning operations on CNC lathes and turning centers. Manufactured to the TLGP-2094L 1125 ISO code, this left-hand insert features a 2.39 mm (0.094 inch) cutting width and a maximum depth of cut of 2.79 mm (0.110 inch). The 1125 grade substrate is finished with a PVD-applied TiCrAlN and TiAlN dual coating, which improves wear resistance and thermal stability during interrupted and continuous grooving cuts. This insert is part of the Top Lok series and is installed and replaced by machinists and CNC toolroom technicians.

This insert is suited for grooving applications in medium-production and high-production turning environments where repeatable groove width and depth control are required. The neutral rake geometry with a 10-degree rake angle supports stable chip formation across a range of workpiece materials. The insert size 2 designation and TLGP style make it compatible with Top Lok series toolholders designed for that seat size. It is well-suited for grooving operations on ferrous and non-ferrous materials where PVD-coated carbide grades are specified.

Compatibility

Designed for use with SANDVIK COROMANT Top Lok series toolholders accepting insert seat size 2 and the TLGP insert style. ISO code reference: TLGP-2094L 1125. Catalog reference number: TLGP-2094L 1125.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. The machine spindle must be fully stopped and the turret locked out before seating or replacing the insert. Use the appropriate Top Lok clamping key or torx driver as specified for the toolholder — do not overtighten the clamping screw by hand force alone. Verify insert seating and clamp engagement before resuming cutting operations.
