Sandvik Coromant 5753188 Grooving Insert TLG3 3020 Solid Carbide

Product Description

The SANDVIK COROMANT 5753188 is a solid carbide grooving insert in the Top Lok series, designed for precision grooving operations on CNC lathes and turning centers. It carries a TiCN and Al2O3 coating applied via MT-CVD process, providing wear resistance and thermal stability under continuous cutting loads. The insert features a right-hand orientation with a 3.17 mm cutting width and a maximum depth of cut of 3.81 mm. With a neutral rake and a 10-degree rake angle, it is suited for stable, controlled chip formation in steel and similar workpiece materials. Machinists and CNC operators working in production turning environments will find this insert fits into the Top Lok toolholder system for quick, repeatable indexing.

This insert is used in external and face grooving applications on CNC turning machines in both job-shop and production settings. It is appropriate for light-to-medium grooving passes where dimensional accuracy and surface finish are critical. The ISO code TLG-3125R 3020 and manufacturer catalog number TLG-3125R 3020 identify this insert within the Top Lok system. The multi-use designation indicates the insert can be repositioned for extended tool life before replacement. Typical applications include part-off grooves, undercuts, and snap-ring grooves in turned components.

• Multi-use insert design extends usable tool life per insert

Compatibility

Designed for use with Top Lok series toolholders accepting insert seat size 3 and a 3.17 mm wide insert. ISO code TLG-3125R 3020 identifies the specific seat and grade pairing within the SANDVIK COROMANT Top Lok system.

Installation Notes

Installation is performed by a qualified CNC machinist or tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate Top Lok clamping key to secure the insert fully before resuming cutting operations. Do not exceed the maximum depth of cut specification for the insert size, and inspect the insert seating surface for chips or debris before each index.
