Sandvik Coromant 5753264 Grooving Insert TLG4 1125 Solid Carbide

Product Description

The SANDVIK COROMANT 5753264 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Part of the Top Lok series, this left-hand insert carries the ISO code TLG-4250L 1125 and is finished with a PVD-applied TiCrAlN and TiAlN dual-layer coating for wear resistance and thermal stability. The insert delivers a cutting width of 0.25 inches (6.35 mm) and a maximum depth of cut of 0.25 inches (6.35 mm), with a neutral rake angle of 10 degrees and a corner radius of 0.023 inches (0.57 mm). It is installed by machinists and toolroom technicians in production and job-shop turning environments.

This insert is suited for grooving, undercutting, and parting applications on ferrous and non-ferrous workpiece materials where consistent groove width and depth control are critical. The Top Lok series is designed for use with compatible Top Lok grooving toolholders in both external and internal grooving configurations. The insert size designation is 4, with an overall length of 0.76 inches and a cutting height of 0.45 inches, making it appropriate for moderate-depth groove profiles in medium-production turning operations. Its multi-use designation allows it to be indexed and reused across compatible toolholder seats.
