Sandvik Coromant 5741745 Cutoff Insert 2.5mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5741745 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the catalog designation R151.2-250 05-5F 2135 and belongs to the T-Max Q-Cut series. The insert features a 2.5 mm (0.0984 inch) cutting width, a 5-degree right-hand lead angle, and a 7-degree relief angle. The 2135 grade substrate is finished with a TiCN/Al2O3/TiN multilayer coating applied via MTCVD, providing wear resistance and thermal stability during interrupted or continuous cuts. Licensed machinists and CNC operators install this insert in compatible T-Max Q-Cut clamp-style toolholders.

This insert is suited for parting off bar stock and grooving operations in general-purpose turning applications. The 5F chipbreaker geometry promotes controlled chip evacuation in materials such as steel and cast iron. The right-hand orientation makes it appropriate for conventional over-center mounting on gang-tool or turret setups. The small corner radius of 0.0039 inch (approximately 0.1 mm) supports precise shoulder definition at the groove wall. It is sold individually with a minimum order quantity of 10 pieces.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully into the clamp pocket and verify the clamping screw torque matches the toolholder manufacturer specification. Inspect the insert seat and clamp for debris or wear before each insert change to maintain accurate cutting geometry.
