Sandvik Coromant 5753128 Grooving Insert TLGP4 1125 Carbide

Product Description

The SANDVIK COROMANT 5753128 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. Grade 1125 carbide substrate is finished with a PVD-applied dual-layer TiCrAlN and TiAlN coating, delivering elevated wear resistance and thermal stability at the cutting edge. The insert provides a 4.8 mm cutting width and a maximum depth of cut of 6.35 mm, with a neutral rake angle of 10 degrees and a corner radius of 0.57 mm. It is installed and serviced by machinists and CNC turning specialists in production and job-shop environments.

The 5753128 is suited for grooving operations on ferrous and non-ferrous workpieces where consistent groove width and controlled chip flow are required. Its right-hand orientation positions it for standard lathe configurations. The multi-use designation indicates the insert is usable across compatible toolholders within the Top Lok system. Typical applications include external groove profiling, undercut machining, and parting on medium-to-small diameter workpieces in both high-volume production and precision one-off turning work.

Compatibility

Designed for use with Top Lok series toolholders accepting insert seat size 4. ISO code TLGP-4189R 1125. Verify toolholder seat geometry and clamping system before installation.

Installation Notes

Installation is performed by qualified machinists following machine tool lockout and energy isolation procedures before insert exchange. Use the appropriate torx or clamping key specified for the Top Lok toolholder to seat the insert fully and evenly — do not overtighten. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Index or replace the insert at first sign of edge wear to maintain groove dimensional accuracy.
