Kyocera TSJ00260 Turning Insert CNMG431 TN60 Cermet

Product Description

The KYOCERA TSJ00260 is a cermet turning insert in the CNMG431 TN60 configuration, designed for precision metal cutting in CNC lathe and turning center applications. It features an 80-degree diamond insert shape, a 0.5-inch inscribed circle, and a corner radius of 0.0156 inches. The TN60 cermet grade carries a TiCN plus NbC coating classification and is engineered for negative rake cutting with a neutral hand orientation. With four available cutting edges, this insert delivers consistent performance across general turning operations. It is appropriate for use by machinists and tooling specialists in production and job shop environments.

This insert is suited for external turning, boring, chamfering, facing, and internal facing operations. The primary target workpiece material is steel, with secondary suitability for stainless steel. The ISOI series designation and compliance with both ANSI and ISO standards make it a practical fit for shops running standardized toolholders. The ISO code for this insert is CNMG120404, and the industry standard number is CNMG431TN60. Material grade classifications are P01, P10, and P20.

Installation Notes

Installation is performed by machinists or tooling technicians on CNC lathes or manual turning centers. The machine spindle must be stopped and the toolholder secured before seating or replacing the insert. Verify that the toolholder pocket and clamping hardware are clean and free of chips before installation. Follow the toolholder manufacturer's recommended clamping torque specifications for CNMG-style inserts.
