Sandvik Coromant 5753066 Grooving Insert TLG3 1125 Solid Carbide

Product Description

The SANDVIK COROMANT 5753066 is a solid carbide grooving insert in the Top Lok series, designed for precision external grooving operations on CNC lathes and turning centers. It carries a dual PVD coating of TiCrAlN and TiAlN, which provides wear resistance and thermal stability at elevated cutting speeds. The insert features a 1.98 mm cutting width, a maximum depth of cut of 2.39 mm, and a neutral rake angle of 10 degrees. Grade 1125 solid carbide construction makes it well suited for consistent, repeatable groove profiles in production turning environments. Licensed machinists and CNC operators install and index this insert as part of routine tooling maintenance.

This grooving insert is intended for use in Top Lok series toolholders and is sized for insert seat size 3. It is a right-hand configuration, making it appropriate for standard left-to-right turning operations on conventional CNC lathe setups. Typical applications include external groove cutting in ferrous and non-ferrous materials where tight width tolerances and controlled depth of cut are required. The multi-use designation indicates it can be applied across a range of compatible grooving applications within the Top Lok system. The ISO code for this insert is TLG-3078R 1125, which can be used to cross-reference compatible toolholder specifications.

Compatibility

Designed for use with Top Lok series grooving toolholders accepting insert seat size 3. ISO code TLG-3078R 1125 should be used to verify toolholder compatibility. No additional compatible model numbers were specified in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop and lockout-tagout procedure applied before indexing or replacing inserts. Ensure the insert seat and clamping surfaces are clean and free of chips before seating the insert. Follow the toolholder manufacturer torque specifications for clamping screws, as over-tightening can fracture the carbide insert. Confirm insert seating and orientation before resuming cutting operations.
