Sandvik Coromant 5737389 Carbide Cutoff Insert 4 Mm T-max Q-cut

Product Description

The SANDVIK COROMANT 5737389 is a solid carbide cutoff and parting insert designed for the T-Max Q-Cut system. It carries insert style N151.2 with a 4.00 mm (0.1575 inch) cutting width and a manufacturer grade of 1005. The TiAlN/TiN coating is applied via PVD process, delivering heat and wear resistance suited to demanding parting and grooving operations. A 0-degree lead angle and 7-degree relief angle define the cutting geometry, while the 0.20 mm (0.0079 inch) corner radius helps control chip formation and surface finish. Neutral hand orientation makes it adaptable across standard parting setups. Licensed HVAC, machining, and metalworking tradespeople specify this insert for precision cutoff work on CNC lathes and turning centers.

This insert is intended for parting and grooving applications on CNC lathes and turning centers where controlled chip evacuation and dimensional accuracy are critical. The 5E chipbreaker geometry is optimized for parting cuts in a range of workpiece materials. Insert seat size 40 matches compatible T-Max Q-Cut toolholders. The clamp holding method ensures secure seating during high-feed parting operations. It is sold individually per package with a minimum order quantity of 10 units.
