Sandvik Coromant 5753211 Grooving Insert TLG4 1125 Solid Carbide

Product Description

The SANDVIK COROMANT 5753211 is a solid carbide grooving insert in the Top Lok series, designed for precision external grooving operations on CNC lathes and turning centers. Manufactured to grade 1125 with a PVD-applied TiCrAlN and TiAlN dual-layer coating, this insert delivers controlled cutting performance in a right-hand orientation. The insert carries a 0.25 inch (6.35 mm) cutting width and a maximum depth of cut of 0.25 inch (6.35 mm), with a neutral rake geometry at a 10-degree rake angle. Installed by CNC machinists and tooling technicians, it is suited for medium to finish grooving passes where dimensional accuracy and edge integrity are critical.

This insert is applicable to turning and grooving operations across a range of workpiece materials where PVD-coated solid carbide tooling is specified. The Top Lok series insert style TLG size 4 fits compatible Top Lok toolholders configured for right-hand grooving. The insert is designated by ISO code TLG-4250R 1125 and manufacturer catalog number TLG-4250R 1125. It is suited for use in production environments requiring consistent groove width repeatability and is listed as a multi-use tool capable of grooving, parting, and profiling within its depth range.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician with the machine in a locked-out, de-energized state before insert exchange. Seat the insert fully into the Top Lok toolholder pocket and verify clamping mechanism engagement before resuming operation. Inspect the insert seat for debris or wear that could affect seating depth and cutting geometry. Follow the toolholder manufacturer torque specifications for the clamping screw.
