CNMG 120412 T6215 turning insert — CVD-coated carbide for stainless steel | Tungaloy

CNMG 120412 T6215 is an ISO‑standard turning insert designed for reliable external and internal turning operations, optimised for stainless steel under stable to lightly interrupted cutting conditions.

• ISO-standard geometry for holder compatibility
• CVD-coated carbide for extended tool life
• Designed for stainless steel machining
• Double-sided chipbreaker with rhombic 80° form

Increased process security through robust coating and geometry

The CVD-coated carbide grade T6215 delivers a reliable barrier against abrasive and adhesive wear, which translates into longer edge life and more predictable tool changes in production environments. With an 80° rhombic geometry and a 1.2 mm nose radius, the insert provides a balance between strength and surface finish, making it suitable for medium-duty turning where component tolerances and repeatability are essential. The ISO-standard form simplifies toolholder selection, reducing setup time and lowering the risk of incompatibility during tool changes.

Predictable integration and mounting for efficient series production

Compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening, size and thickness; the indexable design and cylindrical hole allow secure clamping and straightforward indexing. The plate thickness of 4.76 mm and the inscribed circle of 12 mm are manufactured to ISO dimensions, enabling consistent clamping forces and reproducible results across batches. For production engineers and workshop managers, this predictability reduces scrap rates and supports stable cycle times on CNC lathes, contributing directly to improved throughput.

Controlled chip formation for improved surface quality and reduced rework

The double-sided chipbreaker is tailored for machining stainless steel and assists in producing short, manageable chips under the recommended cutting conditions. Stable chip control helps maintain tool life and reduces the likelihood of chip-related surface damage or machine stoppages, which benefits operators and downstream inspection processes. Where finishing quality is a priority, the combination of the T6215 grade and the insert geometry supports consistent surface integrity with fewer passes, saving time on secondary operations.

FAQ

Is this insert suitable for machining stainless materials?
Yes. The Tungaloy CNMG120412 T6215 insert is formulated for machining stainless steel under stable to lightly interrupted conditions, offering improved wear resistance and chip control.

What is the nose radius and how does it affect the cut?
The insert has a 1.2 mm nose radius, which balances edge strength and surface finish; a larger radius increases strength and stabilises cuts, while a smaller radius is used for finer detail.

How is the insert secured in the holder?
Clamping depends on ISO-standard form, clearance, tolerance class, fastening and thickness; the CNMG geometry with a cylindrical hole enables secure mounting and reliable repeatability when used with compatible holders.

Does the T6215 grade have a coating, and what benefits does it bring?
T6215 is a CVD-coated carbide grade; the coating provides thermal protection and wear resistance, extending tool life and maintaining cutting-edge geometry when machining stainless steel.

Can the insert be indexed to present fresh cutting edges?
Yes. The insert is double-sided with indexed cutting positions, allowing rotation to a new edge when required, which supports efficient tool utilisation.
