Sandvik Coromant 5753646 Grooving Insert TLG3 1125 Solid Carbide

Product Description

The SANDVIK COROMANT 5753646 is a solid carbide grooving insert in the Top Lok series, designed for precision external grooving and turning operations on CNC lathes and turning centers. Built to the TLG-3088L 1125 ISO code, it features a TiCrAlN and TiAlN PVD coating applied over a grade 1125 carbide substrate for extended wear resistance and thermal stability at elevated cutting speeds. The insert is configured for left-hand cutting with a neutral rake angle of 10 degrees, a cutting width of 2.24 mm (0.0880 inches), and a maximum depth of cut of 2.39 mm (0.0940 inches). Machinists and CNC operators in precision machining shops install this insert in compatible Top Lok toolholders for high-repeatability grooving applications.

This insert is suited for grooving operations on ferrous and non-ferrous workpieces in both production and job-shop environments. The size 3 insert seat and Top Lok series designation make it a direct fit for compatible Sandvik Coromant Top Lok grooving toolholders. The multi-use capability allows it to handle grooving, turning, and profiling in a single setup, reducing tool changes on multi-operation parts. A corner radius of 0.19 mm (0.0075 inches) provides a controlled edge geometry suitable for tight-tolerance groove profiles. The depth-of-cut range of 2.00 mm to 3.00 mm gives the operator a defined operating envelope for consistent results.

• Top Lok series, insert seat size 3, ISO code TLG-3088L 1125 for direct toolholder compatibility identification

Compatibility

Designed for use with SANDVIK COROMANT Top Lok series grooving toolholders accepting a size 3 insert seat. ISO code TLG-3088L 1125 identifies the specific holder interface required. Verify toolholder designation against the TLG-3 seat specification before ordering.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and the turret locked before removing or seating the insert. Use the appropriate Sandvik Coromant torque key for the Top Lok clamping screw to ensure proper seating without cracking the carbide. Inspect the insert pocket for chips or debris before installation, as contamination in the seat will affect tool runout and groove accuracy.
