DNMG150404 T6215 DNMG — CVD-coated carbide insert for turning by Tungaloy

The DNMG150404 T6215 is an ISO rhombic turning insert designed for robust stainless‑steel turning under stable to slightly interrupted conditions

• ISO rhombic insert, 55° cutting geometry
• CVD‑coated carbide grade T6215 for wear resistance
• Double‑sided chipbreaker for consistent chips
• Cylindrical‑hole mounting with 0° clearance angle

Durable coating and material for extended tool life

The CVD‑coated carbide T6215 grade is formulated to resist abrasive wear common when machining stainless steels, delivering longer tool life under steady cutting conditions. A CVD (chemical vapour deposition) coating forms a hard outer layer that reduces adhesive wear and helps prevent built‑up edge, which in turn maintains surface quality and reduces the need for frequent tool changes. For production environments where predictable performance and fewer interruptions are priorities, the coated cemented carbide substrate offers a measurable improvement in stand‑time compared with uncoated grades.

Precise ISO geometry for predictable compatibility and secure clamping

The insert follows the ISO DNMG150404 specification so compatibility with suitable external holders depends on the rhombic form, 55° approach angle, 0° clearance angle, tolerance class, fastening method and plate thickness. The 15 mm inscribed circle and 4.76 mm thickness make the insert compatible with standard DNMG holders; the cylindrical hole enables secure clamping and fast index changes. Explaining these parameters helps in selecting the correct holder: the angle and shape determine cutting edge engagement, the thickness and hole style influence how firmly the insert is retained, and the tolerance class ensures repeatable positioning for consistent part geometry.

Improved chip control and process stability for stainless steels

A double‑sided chipbreaker combined with the T6215 grade optimises chip formation when turning stainless steels, which are prone to work‑hardening and long, stringy chips. The chipbreaker design produces short, manageable chips that evacuate reliably, reducing the risk of surface damage or interruptions. In practical terms, this means higher effective cutting times and lower cycle variability, translating into a clearer cost‑benefit in batch production. When process stability and consistent surface finish are priorities, the interplay of geometry and coating provides the core rational advantage.

Practical selection and handling for workshop efficiency

Choose the insert geometry and chipbreaker variant that match material, depth of cut and machine rigidity; for slightly interrupted cuts or where edge strength is essential, the T6215 grade is a robust choice. The 0.4 mm corner radius offers a compromise between edge strength and fine finish—smaller radii yield sharper edges for fine finishing, larger radii increase edge life. Indexing the double‑sided insert reduces tooling inventory and minimises downtime. If further guidance is required on holder matching, cutting parameters or multi‑pass strategies, Metav Werkzeuge can advise on optimal setups for specific stainless‑steel grades.

FAQ

Is this insert suitable for machining stainless steels?
Yes. The DNMG150404 in grade T6215 is specifically intended for turning stainless steels, offering wear resistance and stable performance in continuous to slightly interrupted cuts.

How is compatibility with a toolholder determined?
Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; the DNMG150404 follows ISO dimensions so matching a DNMG‑capable external holder with a cylindrical‑hole clamp and the correct tolerance class ensures secure fitting.

What does the double‑sided chipbreaker mean for production?
A double‑sided chipbreaker allows indexing both sides to form controlled, short chips, improving evacuation, reducing surface damage risk and increasing process stability in serial production.

Which geometry characteristics affect surface finish and edge life?
The 55° cutting approach, 0.4 mm corner radius and the CVD coating are key: the radius balances finish and edge strength, while the coating reduces adhesive wear, together improving repeatable surface quality.

Can the insert be indexed and how often?
The DNMG150404 design with a double‑sided chipbreaker is indexable; when one cutting edge wears, the insert can be rotated or reversed according to the holder design to present a fresh edge, maximising usable edges per insert.
