Kyocera TSJ02170 Turning Insert TNMG432 TN60 Cermet

Product Description

The KYOCERA TSJ02170 is a TNMG432-style indexable turning insert in TN60 cermet grade, coated with TiCN and NbC for improved wear resistance and edge integrity on steel workpieces. The insert features a 60-degree triangle shape with a neutral hand orientation, a 0.5-inch inscribed circle, a corner radius of 0.0313 inches, and an overall insert length of 0.8668 inches. With six cutting edges per insert, it delivers a low cost-per-edge value for production turning operations. This insert is selected and installed by machinists and CNC setup technicians in job shop and production environments running steel components.

This insert is suited for steel turning applications including external turning, facing, boring, chamfering, and copying operations. The TN60 cermet grade targets steel material grades P01, P10, and P20, making it appropriate for finishing and light-to-medium roughing passes on carbon, alloy, and low-alloy steels. The clamp and pin holding method is compatible with standard TNMG-style toolholders used on CNC lathes and turning centers.

Key Features

• TiCN and NbC coating over cermet substrate for extended tool life on steel
• 60-degree triangle insert shape with six usable cutting edges
• Neutral hand — compatible with both left- and right-hand toolholder setups
• 0.0313-inch corner radius for general-purpose finishing and semi-finishing
• Maximum depth of cut of 0.2889 inches for productive material removal
• Multi-use geometry supports boring, chamfering, copying, external turning, and facing in one insert style

Compatibility

Designed as an OEM-style replacement for TNMG432-format indexable inserts used in standard TNMG clamp-and-pin toolholders on CNC lathes and turning centers. ISO code TNMG220408 and industry standard number TNMG432TN60 apply for cross-referencing to compatible toolholder systems.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is stopped and all axis motion is disabled before indexing or replacing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten, as cermet inserts are brittle and can fracture under excessive clamp force. Inspect the toolholder seat and clamp components for wear or debris before seating the new insert.
