TNMG 160404 T9215 — ISO triangular turning insert by Tungaloy

TNMG160404 T9215 is an ISO-standard triangular indexable insert designed for external and internal turning applications in medium-carbon steels.

• TNMG160404 geometry, 60° triangular insert
• CVD-coated carbide grade T9215 for medium steel
• 0.4 mm corner radius for accurate finishing
• Double-sided insert with cylindrical hole for stable clamping

Increase throughput with a wear‑resistant, productive grade

The T9215 grade is a CVD‑coated cemented carbide developed to balance wear resistance and fracture toughness, making it well suited to continuous and lightly interrupted turning in medium steels. This combination reduces flank wear and edge chipping under typical shop conditions, which translates into longer effective cutting lives and fewer tool changes. The result is measurable time savings on serial turning operations and more consistent part quality during long production runs.

Secure clamping and economical tool cycles for reduced downtime

The insert’s triangular shape with a 60° included angle and a cylindrical hole enables simple, repeatable clamping in standard ISO holders. With a double‑sided design and a thickness of 4.76 mm, two cutting edges are available per index, improving cost-efficiency per edge. The geometry details — 16 mm inscribed circle, 0° clearance angle and 0.4 mm corner radius — ensure reliable seat fit and predictable cutting engagement, which aids quick indexing and minimal set‑up time when replacing worn edges.

Consistent surface finish and adaptable chip control

Equipped with a double-sided chipbreaker and tailored for turning, the insert produces stable chip formation across a range of feeds and cutting speeds when matched with appropriate holders and parameters. For practical shop use, select the chipbreaker style and the T9215 grade to match the workpiece alloy and cutting mode; this supports repeatable surface quality and dimensional control. The carbide substrate and CVD coating together provide thermal stability at elevated cutting speeds, helping to keep tolerances within narrow limits and reducing rework.

FAQ

What materials is this insert intended for?
The TNMG160404 T9215 indexable insert from Tungaloy is primarily specified for medium-carbon steel turning, where the T9215 grade provides a balance of wear resistance and toughness.

How does the insert’s geometry affect machining results?
The triangular 60° geometry and 0.4 mm corner radius promote stable cutting engagement and accurate finishing; the double‑sided design reduces tooling costs per edge for repetitive turning tasks.

Is the TNMG160404 compatible with standard ISO toolholders?
Yes. The insert conforms to ISO dimensions and is compatible with holders that match the insert form, relief angle, tolerance class, fixing style, size and thickness.

Can this insert handle interrupted cuts?
The T9215 grade is intended for continuous to slightly interrupted cutting; for heavily interrupted cuts, review holder rigidity and cutting parameters or consider alternative grades.

What is the best way to replace and index the insert?
Use the appropriate ISO holder with the matching seat and fastening system; the cylindrical hole and standard tolerances enable repeatable clamping and quick indexing to the next edge.
