TNMG220408 T6215 Turning Insert (TNMG) — Tungaloy, CVD‑coated carbide, 60°

TNMG220408 T6215 Tungaloy turning insert for ISO‑standard turning applications, designed primarily for machining stainless steels in stable to lightly interrupted cutting conditions

• CVD‑coated carbide T6215, wear resistant
• Double‑sided chipbreaker for consistent chips
• ISO triangular insert, 60° included angle
• Cylindrical hole for secure clamping

Consistent performance for stainless‑steel turning

The T6215 grade is a CVD‑coated carbide developed to offer wear resistance and predictable abrasion behaviour when machining stainless steels. Thanks to the combination of a robust coating and the substrate properties, the cutting edge retains geometry longer in continuous and slightly interrupted cuts, which reduces flank wear and extends productive cutting time. The triangular TNMG form and the 60° included angle provide a stable cutting geometry for external and internal turning, while the double‑sided chipbreaker promotes repeatable chip control. This results in fewer tool changes and improved process stability on lathes and turning centres.

Geometry and holder compatibility explained

The insert follows ISO form and tolerances, so compatibility with external holders or boring bars depends on matching the form, relief angle (0°), tolerance class, clamping arrangement, size (22 mm) and thickness (4.76 mm). The central cylindrical hole and the standard footprint allow straightforward replacement in established clamping systems; however, correct seat fit and the specified tolerance class remain decisive for runout and repeatability. The corner radius of 0.8 mm balances strength and surface finish, making the geometry suitable for general finishing and light roughing when paired with the correct feeds and speeds.

Practical selection and machining advice

For best results, pair the insert with a compatible ISO‑standard holder and choose cutting parameters that reflect the grade characteristics: moderate cutting speeds, stable tool overhangs and controlled depth of cut reduce the risk of work hardening and thermal softening when machining stainless steels. The double‑sided chipbreaker helps maintain consistent chip form across a range of feeds; select the chipbreaker variant that matches material condition and rigidity of the setup. Spare clamping screws and an appropriate backing plate complete the system, enabling quick index changes and reduced machine downtime.
