Sandvik Coromant 5737441 Cutoff Insert 4mm Carbide

Product Description

The SANDVIK COROMANT 5737441 is a solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Cataloged under the T-Max Q-Cut series, this insert carries style designation N151.2 and chipbreaker code 4E. It delivers a 4.00 mm cutting width (0.1575 inches) with a neutral hand orientation and a neutral lead angle of 0 degrees, making it suitable for straight-in parting cuts. The CVD-applied TiCN/TiN coating provides thermal resistance and wear protection during high-speed interrupted cuts. A 7-degree relief angle and a 0.30 mm corner radius (0.0118 inches) define the cutting geometry. Licensed machinists and CNC toolroom operators are the primary installers.

This insert is engineered for parting, cutoff, and shallow grooving applications across a range of workpiece materials. The 4E chipbreaker geometry is suited for controlled chip evacuation in medium-duty turning operations. The clamp-style insert holding method fits compatible T-Max Q-Cut toolholders with a size-40 insert seat. The overall insert length is 6.80 mm (0.2677 inches), and the overall width is 4.00 mm (0.1575 inches). This insert is sold individually with a minimum order quantity of 10 units.

Installation Notes

Cutoff inserts are installed and changed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing any insert. Use the correct clamping screw torque specified by the toolholder manufacturer — do not overtighten. Inspect the insert seat and clamping components for wear or debris before seating a new insert to ensure proper contact and edge stability.
