Sandvik Coromant 5753119 Grooving Insert TLGP4 1125 Solid Carbide

Product Description

The SANDVIK COROMANT 5753119 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Manufactured to the TLGP4 1125 specification within the Top Lok series, this left-hand insert delivers a 4.80 mm (0.189 inch) cutting width and a maximum depth of cut of 6.35 mm (0.250 inch). The PVD-applied TiCrAlN and TiAlN dual-layer coating provides thermal resistance and wear protection during interrupted or continuous grooving passes. Grade 1125 is suited for operations requiring a balance of edge toughness and surface finish quality. Machinists and CNC turning specialists install this insert into compatible Top Lok toolholders.

This insert is intended for use in turning and grooving applications where controlled groove width and depth are critical. The left-hand orientation positions it for specific approach directions on the lathe. With a neutral rake geometry and a 10-degree rake angle, it is appropriate for grooving a range of workpiece materials. The ISO code TLGP-4189L 1125 and catalog number TLGP-4189L 1125 can be used to cross-reference toolholder and insert seat compatibility. It suits both production turning environments and job-shop applications where repeatable groove geometry is required.

Compatibility

Designed as a replacement insert for Top Lok series grooving toolholders accepting insert seat size 4. ISO code TLGP-4189L 1125 and catalog number TLGP-4189L 1125 identify compatible toolholder and seat configurations. Verify toolholder hand orientation and insert seat size before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC toolroom technician with the machine powered down and the spindle locked. Use the appropriate Top Lok clamping key or wrench specified for the toolholder to seat and secure the insert without overtightening. Inspect the insert pocket and clamping surfaces for chips or debris before seating the new insert. Follow the toolholder manufacturer guidelines for torque and clamping procedure.
