Sandvik Coromant 5734245 Cutoff Insert 2.5mm Left Hand

Product Description

The SANDVIK COROMANT 5734245 is a solid carbide cutoff and parting insert designed for precision groove and parting operations on lathes and turning centers. Built to the L151.2 insert style with a 2.5 mm (0.0984 inch) cutting width, this insert carries a 5F chipbreaker geometry and a left-hand lead angle of 5 degrees, promoting controlled chip evacuation during deep parting cuts. The 7-degree relief angle and 0.10 mm corner radius support clean surface finishes on a range of workpiece materials. A PVD-applied TiAlN coating improves heat resistance and edge wear life in demanding production environments. This insert is intended for machinists and CNC turning professionals who require reliable, repeatable cutoff performance.

The 5734245 is used in cutoff and parting applications on CNC lathes and manual turning machines in both production and job-shop environments. The left-hand orientation and 5-degree lead angle make it suited for specific toolholder configurations where insert hand must match the clamp and blade assembly. The T-Max Q-Cut series insert seat size 25 determines compatibility with the appropriate SANDVIK COROMANT blade and holder. Typical applications include bar stock parting, groove turning, and face grooving where a narrow 2.5 mm cutting width is required to minimize material loss.

Compatibility

Designed for use with SANDVIK COROMANT T-Max Q-Cut series toolholders and blades accepting insert seat size 25 with a clamp-style holding method and left-hand insert orientation. Confirm holder and blade specifications before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate torque wrench and clamp screw as specified by the toolholder manufacturer to avoid over-tightening or cracking the carbide insert. Inspect the insert pocket and clamping surfaces for chips or debris before seating the new insert.
