TNMG 220408 T6215 — indexable turning insert, CVD‑coated carbide, for turning

TNMG220408 T6215 is an ISO‑format indexable turning insert designed for stable to lightly interrupted turning operations in stainless steels.

• CVD‑coated carbide grade T6215
• Optimised for stainless steels
• 60° triangular geometry for versatile turning
• 0.8 mm corner radius for robust edge strength

Consistent performance for stainless steel turning

The CVD‑coated carbide in grade T6215 provides a balance of wear resistance and edge stability tailored to stainless steels under stable or lightly interrupted conditions. The coating reduces adhesive wear and improves thermal resistance, which translates into longer edge life and fewer insert changes. For production environments, this means more predictable tool behaviour and reduced downtime, supporting continuous machining and better overall process economy.

Design that simplifies holder compatibility and setup

The insert follows ISO dimensions and a triangular form with a 60° cutting angle and a 0° relief, so compatibility with holders is defined by form, relief angle, tolerance class, clamping method, size and thickness. The indexable insert is supplied with a central cylindrical hole and is double‑sided, enabling economical indexing. These standardised features allow the insert to be integrated into existing toolholders with minimal adjustment, ensuring straightforward setup and repeatable geometry in series production.

Edge geometry and chip control for predictable results

A 0.8 mm corner radius gives a compromise between flank strength and surface finish, reducing the risk of chipping when machining tough stainless alloys. The double‑sided chipbreaker assists consistent chip formation and evacuation in common turning feeds, lowering the likelihood of built‑up edge and improving surface integrity. Selecting the correct chipbreaker and grade for material and stability leads to higher process reliability and fewer rejected parts.

Practical benefits for workshop efficiency

Using a standardised ISO insert such as TNMG220408 reduces inventory complexity and speeds tooling decisions. The combination of CVD coating, robust substrate and triangular geometry delivers a practical compromise between tool life and machining flexibility — ideal for job shops and production lines seeking repeatable results. Clear specification of thickness (4.76 mm), inscribed circle (22 mm) and hole style simplifies procurement and storage planning.

FAQ

What materials is this insert suitable for?
The TNMG220408 T6215 insert is specified for machining stainless steels, with the CVD coating and carbide substrate chosen to resist adhesive and high‑temperature wear.

How does the chipbreaker affect machining?
The double‑sided chipbreaker on the TNMG220408 promotes controlled chip formation and evacuation, improving surface quality and reducing the risk of built‑up edge when turning stainless steel.

Can the insert be used in interrupted cuts?
The T6215 grade is optimised for stable to lightly interrupted turning; heavily interrupted cuts may require a different grade or geometry for improved edge security.

What dimensions are critical for holder selection?
Holder compatibility is determined by the insert’s form, relief angle (0°), tolerance class, clamping method, inscribed circle (22 mm) and thickness (4.76 mm), so these values should match the holder specifications.

How many edges are available before replacement?
The triangular, double‑sided design provides multiple indexable cutting edges, enabling several repositions before the insert requires replacement, supporting cost‑effective tooling cycles.
