Kyocera TSJ02670 Turning Insert TPG222 TN60 Cermet

Product Description

The KYOCERA TSJ02670 is a cermet turning insert in the TPG222 style, designed for precision metal cutting on CNC lathes and turning centers. It features a triangular shape with a 60-degree included angle, three usable cutting edges, and a neutral hand orientation. The TN60 cermet grade is combined with a TiCN and NbC coating classification and is supplied uncoated, offering a material grade range of P01, P10, and P20. With a corner radius of 0.0313 inches and an inscribed circle of 0.25 inches, this insert delivers controlled chip geometry for finishing and semi-finishing operations. Licensed machinists and CNC operators install this insert in compatible ISOI-series toolholders.

This insert is suited for external turning, facing, boring, and chamfering operations on steel and stainless steel workpieces. The positive rake geometry reduces cutting forces, making it effective for lighter depths of cut and tight-tolerance finishing passes. It conforms to both ANSI and ISO standards and carries the ISO code TPGN110308, allowing straightforward cross-referencing. Shops running steel or stainless steel components in production or job-shop environments will find this insert appropriate for a wide range of light to medium turning applications.

Key Features

• Cermet insert material with TiCN and NbC coating chemistry for wear resistance on steel
• Triangular shape with 60-degree included angle and 3 cutting edges for extended tool life
• Positive rake geometry reduces cutting forces during finishing passes
• Corner radius of 0.0313 inches controls surface finish and edge strength
• Multi-use capability: external turning, facing, boring, and chamfering
• Conforms to ANSI and ISO standards; ISO code TPGN110308

Compatibility

Designed for use in ISOI-series TPG-style toolholders. Primary workpiece materials are steel (ISO material code P) and stainless steel. Material grades P01, P10, and P20 indicate suitability for light to medium turning of these materials. Verify toolholder seat size matches the TPG222 insert dimensions before installation.

Installation Notes

Insert installation should be performed by a qualified machinist or CNC tooling technician. Shut down and lock out the machine spindle before seating or indexing the insert. Use the correct clamp-style toolholder designed for TPG inserts and ensure the insert seat is clean and free of chips before clamping. Do not exceed the maximum depth of cut of 0.1445 inches, and always confirm insert seating is secure before starting a cut.
