DCMT 11T304 T6215 — Indexable turning insert for turning applications, Tungaloy

A DCMT 11T304 T6215 indexable insert developed for stable to slightly interrupted turning of stainless steels, offering wear resistance and dependable performance in ISO‑based tool systems.

• CVD-coated carbide grade T6215 for stainless steel
• Rhombic 55° geometry with 0.4 mm corner radius
• Single-sided chipbreaker for reliable chip control
• ISO-compatible with cylindrical hole and countersink

Consistent wear resistance for demanding stainless‑steel turning

The DCMT11T304 insert pairs a CVD-coated surface with a robust carbide substrate to increase run‑time under repetitive cutting and reduce flank wear. The T6215 grade is engineered for the specific demands of stainless steels, where workhardening and abrasive constituents can shorten tool life; the coating enhances thermal stability and abrasion resistance, which in practical terms means fewer interruptions for insert changes and more predictable batch throughput. Explaining briefly: CVD (chemical vapour deposition) applies a hard, adherent layer that protects the carbide substrate from heat and abrasive wear during continuous or lightly interrupted cuts.

Geometry and dimensions that improve surface finish and accessibility

The rhombic 55° geometry with a 0.4 mm corner radius and a 7° clearance provides a balanced combination of strength and accessibility for external and internal turning. A smaller corner radius offers finer edge definition for better surface finish, while the 55° approach angle helps distribute cutting forces evenly, reducing vibration on slender setups. The insert thickness of 3.97 mm and size 11 give mechanical stability in heavier engagement, and the ISO‑standard form ensures predictable seating and repeatability when paired with compatible toolholders.

Controlled chip formation and straightforward integration into tool systems

A single-sided chipbreaker gives reliable chip control, particularly in the medium feed and speed ranges typical for stainless steels, where chip form can otherwise be problematic. The insert features a cylindrical hole with a single-sided countersink (40°–60°) to secure fixation and torque transmission in conventional clamping systems. As part of an ISO‑based system, the insert integrates with matching outside holders, clamping sets and replacement screws, simplifying spare‑part management. If uncertain whether this insert matches a specific holder or application, Metav Werkzeuge can provide technical advice and compatibility checks by e‑mail or phone.

FAQ

What materials is this insert suitable for?
The DCMT11T304 T6215 insert is designed primarily for machining stainless steels, delivering improved wear resistance and process stability when used under the recommended cutting conditions.

What is the corner radius and how does it affect surface finish?
The insert has a 0.4 mm corner radius; this 0.4 mm corner radius helps achieve a finer surface finish while balancing cutting edge strength for general turning tasks.

Which toolholders are compatible with this insert?
The insert conforms to ISO indexable insert standards and, thanks to its form and the cylindrical hole with countersink, fits ISO‑compatible external holders and boring bars when the holder geometry and tolerance class match the insert specifications.

How does the T6215 grade perform in interrupted cuts?
The T6215 CVD‑coated carbide offers robust performance in stable to slightly interrupted conditions; the coating and substrate combination reduces flank and crater wear, extending useful life in such applications.

How does the chipbreaker help in production?
The single-sided chipbreaker shapes chips to improve evacuation and reduce re-cutting, which lowers the risk of workpiece damage and decreases machine downtime for chip clearing.
