DNMG150404 T6215 ISO indexable turning insert, CVD‑coated carbide, for turning — Tungaloy

DNMG150404 T6215 is an ISO‑standard rhombic indexable insert for external and internal turning, designed for machining rostfreier Stahl using a wear‑resistant CVD‑coated carbide grade under stable to lightly interrupted conditions.

• CVD‑coated carbide for high wear resistance
• Optimised for machining rostfreier Stahl
• Rhombic 55° geometry, 0.4 mm nose radius
• Cylindrical‑hole design, 4.76 mm thickness

Engineered for productivity and predictable tool life

The DNMG150404 T6215 insert pairs a CVD coating with a robust carbide substrate to extend edge life during demanding turning operations. This combination reduces flank wear and maintains a stable cutting edge over longer periods, which in turn lowers tool change frequency and increases machine uptime. The balanced geometry supports efficient chip evacuation and contributes to consistent surface quality, so process stability and throughput are improved without sacrificing component finish.

Interchangeability and secure clamping for simple integration

Compliance with ISO dimensions means the insert fits common holders and boring bars when form, clearance angle, tolerance class, attachment method, size and thickness match. The cylindrical‑hole fastening style and a plate thickness of 4.76 mm provide secure clamping and torsional stability in the pocket. Where replacement screws or shims are required, the insert integrates into standard system assemblies, allowing quick swaps and predictable seating for serial production.

Performance advantages when machining rostfreier Stahl

The T6215 grade is designed for rostfreier Stahl, offering wear resistance under stable to lightly interrupted conditions. The double‑sided chipbreaker supports controlled chip formation, assisting coolant flow and reducing the risk of built‑up edge. The 0.4 mm nose radius presents a compromise between strength and surface finish: it supports higher feed rates with adequate robustness while still enabling a fine finish when required by the workpiece specification.

Selecting the right insert geometry and chipbreaker

Choosing an insert involves matching the 55° rhombic geometry and nose radius to the part tolerance and clamping rigidity. A larger nose radius improves component integrity but increases cutting forces; the 0.4 mm radius here is a versatile option for many medium‑precision turning tasks. For less stable set‑ups or heavily interrupted cuts, opting for a more protective geometry or different grade is recommended. The double‑sided chipbreaker simplifies inventory management by providing two usable edges per index.

FAQ

What materials is this insert designed for?
The Tungaloy DNMG150404 T6215 insert is formulated for machining rostfreier Stahl and performs best under stable to lightly interrupted cutting conditions.

How does the 0.4 mm nose radius affect machining?
A 0.4 mm nose radius on the DNMG150404 balances edge strength and surface finish, allowing moderate feeds while maintaining dimensional stability.

Is the insert reversible and how many cutting edges are available?
The DNMG150404 T6215 is double‑sided with two usable cutting edges per index, supporting efficient re‑indexing and economical tool usage.

What clamping style does the insert use?
This insert features a cylindrical‑hole clamping design for secure mounting in compatible ISO holders and boring bars.

Can this insert be used with interrupted cuts?
Yes; the T6215 grade is intended for stable to lightly interrupted conditions. For heavy interruptions, consider a more robust grade or geometry.
