Sandvik Coromant 5737055 Grooving Insert Corocut 1-2

Product Description

The SANDVIK COROMANT 5737055 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Carrying the ISO designation N123K2-0635-0003-GM 1125, it features a 6.35 mm (0.25 inch) cutting width and a maximum depth of cut of 22.6 mm (0.8898 inch). The TiAlN PVD coating provides heat resistance and extended tool life in demanding materials. The GM chip breaker geometry promotes controlled chip formation. This insert is installed by machinists and CNC operators working in production turning environments.

The 5737055 insert belongs to the CoroCut 1-2 series, a platform engineered for grooving, parting, and turning applications. It is suitable for both roughing and finishing passes within the maximum depth of cut range of 20 mm and above. The neutral hand orientation makes it compatible with both left-hand and right-hand holder configurations. Typical applications include groove turning on ferrous and non-ferrous workpieces in job shop and high-volume production settings.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before changing inserts. Use the correct insert key and torque the clamping screw to the toolholder manufacturer specification found in the holder documentation — do not estimate torque. Inspect the insert seat and clamping surfaces for chips or debris before seating the new insert.
