Sandvik Coromant 5753082 Grooving Insert TLG3 Left Hand

Product Description

The SANDVIK COROMANT 5753082 is a solid carbide grooving insert in the Top Lok series, designed for precision grooving and parting operations on CNC lathes and turning centers. Built to ISO code TLG-3072L 1125, this left-hand insert features a PVD-applied TiCrAlN and TiAlN dual-layer coating that extends tool life in demanding cutting conditions. The 1.83 mm cutting width and a maximum depth of cut of 2.39 mm suit it to tight-tolerance groove profiles in ferrous and non-ferrous materials. Manufacturer grade 1125 and a neutral rake geometry round out the specification. Licensed machinists and CNC operators are the primary installers of this insert type.

This insert is intended for grooving, undercutting, and light parting operations on turning centers equipped with Top Lok-compatible toolholders. The left-hand orientation suits specific radial and axial grooving positions on the spindle. With a corner radius of 0.19 mm and a cutting height of 8.74 mm, it is well suited to small-bore grooving and external groove profiles where dimensional accuracy is critical. The insert size is 3, and it is catalogued under Sandvik Coromant part number TLG-3072L 1125.

• Left-hand cut orientation for specific grooving positions on turning equipment
• 1.83 mm cutting width with a maximum depth of cut range of 2.00 to 3.00 mm
• Neutral rake with 10-degree rake angle for balanced chip control
• Multi-use insert compatible with Top Lok series toolholders

Compatibility

Designed for use with Top Lok series grooving toolholders that accept insert seat size 3. Specific compatible toolholder model numbers should be confirmed against the Sandvik Coromant Top Lok toolholder selection guide for insert size 3, left-hand orientation.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist with the machine in a full stop, locked-out, and tagged-out condition per applicable shop safety procedures. Use the appropriate Torx or hex key as specified by the toolholder manufacturer when seating the insert to avoid cracking the carbide substrate. Do not re-index or reuse an insert that shows visible chipping, edge wear, or coating breakdown. Verify insert hand orientation and seat size against the toolholder specification before engaging a cut.
