Sandvik Coromant 5846589 Grooving Insert TLGP3 1125 Carbide

Product Description

The SANDVIK COROMANT 5846589 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to the Top Lok series standard, it carries grade 1125 and features a dual-layer PVD coating of TiCrAlN and TiAlN for extended tool life in demanding cutting conditions. The insert delivers a cutting width of 0.110 inches (2.79 mm) and a maximum depth of cut of 0.150 inches (3.81 mm), making it well-suited for controlled, repeatable groove profiles. Machinists and toolroom technicians working with ferrous and non-ferrous workpieces install this insert as a direct-fit replacement in compatible Top Lok toolholders.

This insert is intended for use in production turning environments where groove geometry consistency and surface finish are critical. It is a right-hand insert with a neutral rake angle of 10 degrees, appropriate for general-purpose grooving on medium to hard workpiece materials. The ISO code TLGP-3110R 1125 and catalog number TLGP-3110R 1125 provide direct cross-reference to SANDVIK COROMANT toolholder systems. Typical applications include external groove profiles, undercuts, and parting operations on bar-fed or chucked workpieces in both job shop and production environments.

Compatibility

Designed for use with SANDVIK COROMANT Top Lok series toolholders accepting insert seat size 3. ISO code TLGP-3110R 1125 and catalog number TLGP-3110R 1125 serve as direct cross-references for toolholder and insert system matching.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or replacing the insert. Verify correct insert orientation and confirm the insert is fully seated in the Top Lok pocket before resuming cuts. Do not exceed the published maximum depth of cut range for the insert size and grade.
