Sandvik Coromant 5753326 Grooving Insert TLGP3142 2135

Product Description

The SANDVIK COROMANT 5753326 is a solid carbide grooving insert designed for precision external grooving operations on CNC lathes and turning centers. It carries ISO code TLGP3142R2135 and belongs to the Top Lok series, offering a cutting width of 0.142 inches and a maximum depth of cut of 0.150 inches. The grade 2135 substrate is finished with a multilayer MT-CVD coating of TiCN, Al2O3, and TiN, providing wear resistance and thermal stability during interrupted and continuous cuts. Machinists and CNC operators install this insert as a right-hand orientation replacement in compatible Top Lok toolholders.

This insert is suited for grooving applications in production turning environments, both light-duty and moderate-material-removal operations. The Top Lok series is commonly used in aerospace, automotive, and general machining shops where repeatable insert indexing and consistent groove geometry are required. With a 10-degree rake angle and a 0.0125-inch corner radius, it is well suited for producing narrow, accurate grooves in steel and other machinable alloys. The multi-use designation indicates it supports grooving, parting, and related operations within its depth range.

Compatibility

Designed for use in Top Lok series toolholders accepting TLGP3142 style inserts. Confirm toolholder insert seat specifications before installation. No additional compatible model numbers were specified in the available product data.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Always index or replace inserts with the machine powered down and spindle locked. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer — do not over-tighten the clamping screw, as this can fracture the carbide insert. Verify insert orientation and seating before resuming cutting operations.
