Sandvik Coromant 5741577 Cutoff Insert 4mm Right Hand

Product Description

The SANDVIK COROMANT 5741577 is a solid carbide cutoff insert designed for precision parting and grooving operations on CNC lathes and turning centers. Built to Insert Style R151.2 in manufacturer grade 2135, this insert features a 4.00 mm cutting width (0.1575 inches) and a 5-degree right-hand lead angle. The MTCVD coating process applies a TiCN/Al2O3/TiN multilayer finish that resists heat and wear in continuous and interrupted cut conditions. Licensed machinists and CNC operators install this insert as part of the T-Max Q-Cut system, using a clamp holding method for secure, repeatable indexing.

This insert is suited for parting off bar stock and grooving operations in both production and job-shop turning environments. The 5E chipbreaker geometry promotes chip control during cutoff, reducing the risk of chip packing in the groove. The right-hand insert hand and right-hand lead angle direction make it appropriate for standard spindle-direction turning setups. The overall insert length is 7.00 mm (0.2756 inches), with a corner radius of 0.20 mm (0.0079 inches) and a 7-degree relief angle for clearance in tight groove profiles.

Key Features

• Solid carbide construction in manufacturer grade 2135 for thermal and wear resistance
• MTCVD-applied TiCN/Al2O3/TiN coating for extended tool life in steel and cast iron
• 4.00 mm cutting width with 5E chipbreaker geometry for effective chip control during parting
• 5-degree right-hand lead angle reduces cutting forces and directs chips away from the workpiece
• 0.20 mm corner radius minimizes stress concentration at groove root
• Clamp holding method compatible with T-Max Q-Cut toolholders for rigid, repeatable seating

Compatibility

Designed for use in the Sandvik Coromant T-Max Q-Cut system with Insert Style R151.2, Insert Size Code 40, and Insert Seat Size 40. Manufacturer catalog number R151.2-400 05-5E 2135 corresponds directly to this insert.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Confirm the machine spindle is fully stopped and all axes are at a safe position before indexing or replacing inserts. Use the appropriate clamp screw torque specified by the toolholder manufacturer — do not overtighten, as this can fracture the insert. Inspect the insert seat and clamp for debris or damage before seating a new insert to ensure proper contact and alignment.
