SNMG120404 T6215 — ISO turning insert, CVD‑coated carbide, 0.4 mm radius | Tungaloy

A SNMG120404 T6215 indexable insert engineered for ISO‑standard external and internal turning, designed to maintain process stability when machining stainless steels under stable to lightly interrupted cutting conditions.

• ISO‑standard square insert, 12 mm
• CVD‑coated carbide grade T6215
• Designed for stainless steel turning
• Double‑sided with 0.4 mm corner radius

High wear resistance for stainless steel machining

The grade and coating combination deliver a clear advantage when machining stainless steel: CVD‑coated carbide with the T6215 grade provides enhanced wear resistance and thermal stability compared with uncoated grades. This reduces flank wear during longer cycles and helps maintain consistent dimensional tolerances. The coating’s resistance to built‑up edge formation supports stable cutting at moderate feeds and speeds, which in turn contributes to predictable tool life and fewer unscheduled tool changes.

ISO compatibility and simple holder matching

Supplied in the familiar ISO configuration, the insert is compatible with established holders when form, clearance angle, tolerance class, fastening method, size and thickness are matched. The square shape and the presence of a cylindrical hole allow secure clamping in many standard external holders and boring bars, simplifying tool inventory. Using an ISO‑compliant insert streamlines holder selection and reduces setup time, improving machine uptime and repeatability across batches.

Geometry tuned for surface quality and stability

The geometry of the insert, including the corner radius 0.4 mm and the double‑sided chipbreaker, is tuned for a balance between finish and edge strength. The relatively small radius supports good surface finish on light finishing passes while still providing enough edge strength for short interruptions. The double‑sided design extends service life by enabling rotation to a fresh cutting edge, and the 4.76 mm thickness contributes to rigidity at the clamping point, reducing vibration and enhancing dimensional control.

Practical benefits for production and process reliability

Specified for external and internal turning operations, the insert supports productive machining where consistent results and low variation are priorities. The reversible nature and ISO format lower per‑part tooling costs when compared to fully brazed solutions, and the Tungaloy grade selection promotes stable chip formation in common stainless‑steel alloys. For customers seeking application guidance or verification of holder compatibility, technical consultation can ensure the chipbreaker and grade match the workpiece, feed and machining strategy to optimise output and part quality.

FAQ

Which materials is this insert intended for?
The SNMG120404 T6215 insert from Tungaloy is specified for machining stainless steel under stable to lightly interrupted conditions and performs well where good wear resistance is required.

Is the insert indexable and reversible?
Yes, the square SNMG design is double‑sided, allowing rotation to a fresh cutting edge to extend usable life and reduce tooling costs.

What size and thickness does the insert have?
The insert measures 12 mm with a thickness of 4.76 mm and a corner radius of 0.4 mm, suitable for a wide range of ISO holders.

Does the insert require a specific holder type?
Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; the SNMG120404 fits standard ISO holders that accept square inserts with a cylindrical hole.

What advantages does the T6215 grade provide?
The T6215 grade is a CVD‑coated carbide that offers improved wear resistance and stable chip formation when turning stainless steel, supporting consistent surface quality and longer tool life.
