TNMG220408 T6215 Turning Insert – CVD-coated carbide, 0.8 mm nose radius | Tungaloy

The TNMG220408 T6215 is an ISO-standard triangular indexable insert designed for external and internal turning of stainless steels under stable to lightly interrupted cutting conditions

• CVD-coated carbide for long tool life
• Optimised for stainless steel turning
• Double-sided chipbreaker for stable chips
• Triangular 22 mm plate, 0.8 mm radius

Long-lasting performance for stainless steel turning

The CVD-coated carbide grade T6215 delivers wear resistance and consistent edge stability in demanding stainless steel applications. With the 60° included angle and a 0.8 mm nose radius, the insert balances cutting-edge strength and surface finish, reducing the need for frequent index changes. This results in fewer interruptions and predictable tool life, which supports higher machine uptime and a steadier production flow.

Straightforward ISO compatibility and safe clamping

Produced to ISO dimensions, the insert is compatible with ISO holders where form, relief angle, tolerance class, fastening and size match. The insert is supplied with a cylindrical hole and a standard clamping interface, so secure mounting and repeatable seating are ensured. Using ISO-compliant cartridges or boring bars simplifies stock management and lowers the risk of fitting errors, allowing faster changeovers and reliable repeatability.

Better surface quality with controlled chip formation

The double-sided chipbreaker is engineered for consistent chip control during both external and internal turning, improving process stability and surface integrity. Combined with a 4.76 mm plate thickness and the 22 mm triangular format, the geometry increases rigidity at the cutting edge, reducing chatter and improving finish. The result is a predictable part quality with less rework and fewer downstream corrections.

Practical selection and productivity benefits

Selecting the correct chipbreaker and T6215 grade for the material and machining stability yields measurable productivity gains: longer tool life, fewer tool changes and lower scrap rates. The insert’s reversible design effectively doubles indexable time per component, offering economical use in batch and continuous production. For trials or variable feeds, the insert supports a broad range of cutting parameters when matched to the appropriate holder and cutting data.

FAQ

What materials is this insert best suited for? The TNMG220408 T6215 insert is designed primarily for machining stainless steel under stable to slightly interrupted cutting conditions, taking advantage of the T6215 CVD-coated carbide for wear resistance.

Is the insert reversible and how many cutting edges are available? Yes, the triangular geometry with a double-sided chipbreaker makes the insert indexable and reversible, providing multiple usable cutting edges to extend effective tool life.

Which holders are compatible with this ISO-format insert? Compatibility depends on ISO form, relief angle, tolerance class, fastening method, size and thickness; the TNMG220408 is made to ISO dimensions and fits standard ISO turning holders and boring bars when those parameters match.

What are the key dimensions to check before ordering? Confirm the 0.8 mm nose radius, 60° included angle, 22 mm plate size and 4.76 mm thickness to ensure correct fit and expected cutting performance.
