TNMG 160412 T9215 – TNMG turning insert by Tungaloy, CVD-coated carbide

TNMG160412 is an ISO‑standard indexable turning insert designed for medium‑steel machining with a robust CVD coating for extended tool life.

• CVD-coated carbide grade T9215
• Optimised for medium steel machining
• Double-sided triangular insert
• Cylindrical-hole, ISO-compatible design

High wear resistance for productive medium-steel turning

The combination of CVD-coated carbide and the T9215 grade provides a measured balance between wear resistance and fracture toughness, making the insert especially suitable for continuous to lightly interrupted turning of medium steel. The CVD layer increases surface hardness and heat resistance, which reduces flank wear and helps maintain consistent cutting geometry over longer tool life. As a result, cycle times can be shortened and tool-change frequency reduced, supporting higher throughput on repetitive turning operations.

Geometry and compatibility for predictable tool life

A double-sided, triangular geometry delivers two usable cutting edges per side, improving insert utilisation and lowering tooling cost per part. The 1.2 mm corner radius offers enhanced edge strength for general turning tasks while balancing surface finish—larger radii increase edge life, smaller radii improve detail and finish. The insert features a cylindrical hole and ISO‑conforming form, with compatibility to holders determined by form, relief angle, tolerance class, fastening, size and thickness. The 0° relief angle and 60° geometry ensure predictable contact and force distribution for stable machining.

Application guidance for consistent, process-safe results

Designed for external and internal turning, the insert performs best when matched with a suitable chipbreaker and the correct cutting data for the chosen workpiece and machine stability. For medium‑steel components produced under stable cutting conditions, the grade’s blend of wear and fracture resistance supports higher material removal rates and consistent surface quality. Where interrupted cuts or unstable setups occur, selecting an appropriate chip control variant and moderating feed rates preserves edge integrity and avoids premature edge chipping, thereby safeguarding process reliability and repeatability.

FAQ

What materials is this insert suited for?
The TNMG160412 T9215 insert is optimised for medium steel machining; the CVD-coated carbide grade offers a balance of wear resistance and toughness for productive turning.

How does the insert’s geometry affect performance?
A triangular, double-sided form offers multiple cutting edges and economical use, while a 1.2 mm corner radius increases edge strength and helps prevent premature chipping under moderate cutting loads.

What determines compatibility with an indexable holder?
Compatibility is defined by form, relief angle, tolerance class, fastening type, plate size and thickness; holders must match the ISO geometry and fastening method for secure clamping.

Is the T9215 grade suitable for interrupted cuts?
T9215 combines wear resistance with fracture safety and is suitable for continuous to lightly interrupted cuts; for severe interruptions, select a chipbreaker and cutting data adjusted to the application.

What is the article and manufacturer identification for ordering?
The insert is listed as article number 6772337 (SKU 6772337-Tungaloy), manufacturer SKU TUN6772337, supplied by Tungaloy.
