TNMG 160408 T9215 — Turning insert (Drehen) by Tungaloy

A TNMG160408 ISO-standard triangular insert for general turning and internal/external operations, optimised for medium steel machining with a CVD-coated carbide grade for high productivity.

• CVD-coated carbide grade T9215
• Robust edge for medium steel cutting
• Double-sided triangular insert for cost efficiency
• Compatible with ISO turning holders

Consistent productivity for medium steel turning

The CVD-coated carbide grade delivers high wear resistance and fracture toughness, which translates into longer tool life and fewer indexings during serial turning. The insert is designed primarily for medium steel applications and performs well under continuous to lightly interrupted cuts. As a result, cycle times remain predictable and machining costs per component fall; the coating and substrate combination helps maintain a stable cutting edge even at elevated cutting speeds, supporting higher productivity without sacrificing workpiece quality.

Easy integration with ISO tooling systems

Thanks to its ISO-standard form and defined geometry, the insert provides reliable compatibility with a wide range of ISO turning holders. The triangular shape and double-sided chipbreaker allow two indexing positions per side, increasing usable life and reducing tooling inventory turnover. The central cylindrical hole and standard attachment arrangement ensure secure clamping and consistent seat location, simplifying tool set-up and repeatability across machines and operators.

Geometry that supports surface finish and process stability

The insert’s dimensions—16 mm inscribed size with a 4.76 mm thickness and a 0.8 mm corner radius—are matched to common holder profiles and turning applications that require a balance between strength and finish. The included 60° whole-plate angle and a 0° relief angle yield predictable cutting forces and stable chip formation when paired with the right feed and speed. The double-sided chipbreaker promotes controlled swarf evacuation, which benefits surface quality and reduces the likelihood of built-up edge on steel materials.
