Sandvik Coromant 5753757 Grooving Insert TLGP3 1125 Solid Carbide

Product Description

The SANDVIK COROMANT 5753757 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. It carries a dual-layer PVD coating of TiCrAlN and TiAlN under manufacturer grade 1125, delivering wear resistance and thermal stability in demanding cuts. The insert features a 2.46 mm cutting width, a maximum depth of cut of 3.81 mm, and a neutral rake angle of 10 degrees, making it suitable for a range of workpiece materials. Machinists and CNC turning specialists install this insert as a direct replacement in Top Lok toolholders.

This grooving insert is used in production and job-shop turning environments where consistent groove geometry and surface finish are required. It is sized for insert seat size 3 and is oriented for right-hand cutting. The ISO code for this insert is TLGP-3097R 1125, and the manufacturer catalog number matches that designation. It is well suited to applications requiring tight width tolerances on grooves in ferrous and non-ferrous workpieces, including general-purpose turning on medium to large CNC lathes.

Installation Notes

This insert is installed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate Top Lok clamping key or wrench to seat and secure the insert fully in the pocket — do not force or overtighten by hand. Inspect the insert seat for chips or contamination before seating a new insert to ensure proper contact and geometry.
