TNMG220408 T9215 – ISO turning indexable insert for external and internal turning (Tungaloy)

TNMG220408 T9215 is an ISO‑standard triangular turning insert designed for general turning applications, offering robust wear resistance and optimised chip control for medium steel machining.

• CVD-coated carbide T9215 for medium steel
• ISO‑standard TNMG 220408 triangular insert
• 0.8 mm nose radius for precise profiles
• Double‑sided geometry with cylindrical hole

Consistent productivity through a wear‑resistant coating

The insert combines a CVD‑coated carbide substrate with the T9215 grade to deliver high wear resistance and good fracture resistance in continuous to lightly interrupted cuts. The CVD coating forms a thin, hard layer that reduces flank wear and increases component lives; this means fewer index changes and a lower cost per part during medium steel turning. The result is reliable, repeatable performance under production conditions.

Accurate profiles and improved surface finish

A 0.8 mm nose radius on a 60° triangular geometry provides the balance between profile definition and surface quality. A larger nose radius smooths the cutting action and reduces vibration, which improves finish without compromising dimensional control. The corner radius and geometry make the insert suitable for both finishing passes and light profiling, translating technical dimensions into tangible surface benefits.

Straightforward system compatibility for quicker setup

The insert conforms to ISO dimensions, so compatibility with holders is determined by form, relief angle, tolerance class, clamping method, size and thickness. Matching an ISO‑compliant external holder or boring bar ensures correct seating and clamping force. Understanding these interface criteria reduces setup time and enhances tool life by preventing misalignment or improper clamping that can cause premature wear or edge failure.

Efficient chip control and economical use

The double‑sided chipbreaker geometry together with a cylindrical locating hole enables controlled chip formation and secure fastening. Being indexable on both sides halves the effective tooling cost per cutting edge, while the designed chip control aids evacuation in continuous cuts. This combination supports higher material removal rates and contributes to a more efficient machining cycle with fewer interruptions.

FAQ

What materials is this insert best suited for?
The Tungaloy TNMG220408 T9215 insert is optimised for medium steel machining; the T9215 grade combines wear resistance and toughness for productive steel turning.

What does the T9215 designation mean for performance?
T9215 denotes a CVD‑coated carbide grade designed to balance high wear resistance with good fracture toughness, making the insert suitable for continuous to lightly interrupted cuts.

How does the 0.8 mm nose radius affect machining results?
A 0.8 mm nose radius improves surface finish and reduces vibration during turning, helping to achieve accurate profiles while maintaining an acceptable tool life.

Is the insert compatible with standard ISO holders?
Yes; the insert matches ISO dimensions, but compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness. Correct holder selection ensures proper seating and performance.

Can the insert be indexed to use multiple cutting edges?
The triangular, double‑sided design allows indexing of multiple cutting edges, effectively reducing cost per edge and increasing uptime between tool changes.
