Kyocera TSJ03571 Turning Insert VNMG3305GP TN60 Cermet

Product Description

The KYOCERA TSJ03571 is a cermet turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. Manufactured to ANSI and ISO standards, this insert carries the VNMG160402GP ISO designation and the industry standard number VNMG3305GP TN60. It features a 35-degree diamond shape with a negative rake angle of -10 degrees and a honed cutting edge style. The TN60 cermet grade includes a TiCN and NbC coating classification and is engineered for high-surface-finish applications in steel and stainless steel cutting. Four usable cutting edges per insert make it a cost-efficient choice for production turning environments.

This insert is suited for external turning, facing, copying, and undercutting operations, primarily in steel and stainless steel workpieces. It fits into standard VNMG-style toolholders with clamp and pin holding methods. The neutral hand orientation makes it compatible with right-hand tooling setups on conventional and CNC lathes. Typical users include machinists and CNC operators in job shops and production facilities working with P-grade workpiece materials at finish to semi-finish material removal rates corresponding to grades P01, P10, and P20.

Key Features

• 35-degree diamond insert shape (Shape Code V) with negative rake for controlled chip formation
• TN60 cermet grade with TiCN and NbC composition for extended tool life in steel finishing
• Four cutting edges per insert reduce per-edge tooling cost
• GP chip breaker geometry supports copying, facing, external turning, and undercutting
• Honed cutting edge style minimizes edge chipping on interrupted or continuous cuts
• Meets ANSI and ISO standards; ISO Code VNMG160402GP for direct cross-reference

Compatibility

Designed as an OEM-style replacement for VNMG-style turning insert applications. Compatible with standard VNMG toolholders using clamp and pin holding methods. Refer to the ISO Code VNMG160402GP or industry standard number VNMG3305GP TN60 for direct cross-reference to equivalent inserts from other manufacturers.

Installation Notes

Installation of turning inserts should be performed by a qualified machinist or CNC operator with the machine powered down and spindle locked before seating or replacing the insert. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer to secure the insert without over-tightening. Inspect the insert pocket and locating pin for wear or debris before seating a new insert. Follow facility safety protocols and applicable machine tool standards when handling sharp cutting inserts.
