Sandvik Coromant 5753053 Grooving Insert TLG3 1125 Left Hand

Product Description

The SANDVIK COROMANT 5753053 is a solid carbide grooving insert in the Top Lok series, designed for precision external grooving and parting operations on CNC lathes and turning centers. It carries a TiCrAlN and TiAlN PVD coating for improved wear resistance and thermal stability during interrupted or continuous cutting. The insert is left-hand orientation with a 1.98 mm (0.0780 inch) cutting width and a maximum depth of cut of 2.39 mm (0.0940 inch). The ISO code is TLG-3078L 1125 and the manufacturer grade is 1125. Machinists and CNC turning specialists install this insert in compatible Top Lok toolholders for grooving ferrous and non-ferrous workpiece materials.

This insert is suited for use in production turning environments where consistent groove geometry and surface finish are critical. The TLG style, size 3 insert seat, and neutral rake geometry make it applicable to a wide range of groove profiles. The multi-use designation means a single insert can serve multiple grooving passes within its depth-of-cut range of 2.00 mm to 3.00 mm. It is typically installed in machining cells running medium to high production volumes on bar-fed lathes or chucking machines. CNC machinists and tool-and-die professionals are the primary users.

Compatibility

Designed for use with SANDVIK COROMANT Top Lok series toolholders that accept a size 3 insert seat. ISO code TLG-3078L 1125 and manufacturer catalog number TLG-3078L 1125 should be used to confirm holder compatibility before installation.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. The machine spindle must be fully stopped and all stored energy discharged before changing inserts. Use the appropriate Top Lok clamping key or wrench specified by SANDVIK COROMANT for the toolholder; do not use substitute tools that could damage the insert seat or clamping mechanism. Verify insert orientation — left-hand — matches the toolholder hand before seating the insert to avoid workpiece interference or insert breakage.
