DCMT 11T304 T6215 turning insert for stainless steel — Tungaloy

A DCMT11T304 T6215 turning insert designed for ISO-standard external and internal turning of stainless steels under stable to mildly interrupted conditions

• CVD-coated carbide for high wear resistance
• Rhombic DCMT shape with 55° cutting angle
• 0.4 mm corner radius for fine profiling
• Cylindrical hole with single-sided countersink

Durable cutting performance for stainless steels

The CVD-coated carbide grade T6215 delivers wear resistance optimised for the demands of machining stainless steel, extending tool life and reducing changeover frequency. The coating acts as a thermal and abrasive barrier, which keeps the cutting edge stable under continuous and slightly interrupted cuts. This stability translates directly into fewer tool interventions and more consistent production runs, supporting efficient cycle times and predictable component quality.

Secure mounting and ISO compatibility for flexible setups

Built to the ISO specification, the rhombic DCMT form ensures reliable compatibility with a wide range of external holders and boring bars; compatibility depends on the insert’s form, relief angle, tolerance class, clamping method, size and thickness. The 55° cutting angle and 7° relief are engineered to balance cutting force and accessibility in confined geometries, while the cylindrical hole with a single-sided countersink (40°–60°) provides positive seating and repeatable clamping. This results in stable machining across different toolholders and setups.

Precision results with minimal finishing

A 0.4 mm corner radius offers a compromise between strength and surface quality: small enough for accurate profiling and fine-detail work, yet large enough to protect the cutting edge during moderated depths of cut. The plate thickness of 3.97 mm contributes to rigidity and vibration damping, and the one-sided chipbreaker aids controlled chip formation on turning operations. Together these attributes support improved surface finish and dimensional consistency, reducing downstream rework and inspection time.

FAQ

What materials is this insert suitable for?
The Tungaloy DCMT11T304 T6215 insert is formulated for machining stainless steels and performs well in both external and internal turning operations where stable or mildly interrupted cutting occurs.

How does the T6215 grade affect tool life?
Grade T6215 with its CVD-coated carbide offers enhanced wear resistance and thermal protection, which typically extends tool life and maintains edge integrity under continuous stainless steel machining.

Is the insert compatible with standard ISO holders?
Yes, the rhombic DCMT11T304 form is ISO-standard; compatibility depends on holder form, relief angle, tolerance class, clamping method, size and thickness for secure and repeatable mounting.

What is the purpose of the 0.4 mm corner radius?
A 0.4 mm corner radius provides a balance of cutting-edge strength and the ability to produce finer surface finishes, making it suitable for profiling and finishing where controlled chip flow is required.

How does the hole and countersink design benefit clamping?
The cylindrical hole with a single-sided countersink (40°–60°) offers positive seating and consistent clamping torque, improving repeatability and reducing insert movement during heavier passes.

Can this insert be used for interrupted cuts?
Yes, the insert grade and geometry are intended for stable to slightly interrupted cutting conditions; for heavily interrupted applications, consult process parameters and Metav Werkzeuge for suitability.
