DNMG150404 T6215 — Turning indexable insert by Tungaloy (CVD‑coated carbide, 0° clearance)

DNMG150404 T6215 is a compact ISO‑format turning insert for external and internal turning operations, optimised for stainless steels under stable to lightly interrupted cutting conditions.

• ISO DNMG150404 format for standard holders
• CVD‑coated carbide grade T6215 for stainless steel
• 0.4 mm nose radius for precise profile control
• Double‑sided chipbreaker, cylindrical‑hole design

High‑performance grade for stainless steel turning

The CVD‑coated carbide grade T6215 is engineered for wear resistance and reliable life when machining stainless steels, offering a balanced combination of toughness and hardness. The chemical vapour deposition (CVD) coating enhances resistance to abrasive wear and built‑up edge formation; this translates into longer tool life and more consistent component surfaces. For production environments where repeatability and predictable reconditioning intervals matter, the coated grade reduces downtime and supports steady output rates while maintaining dimensional stability.

Precision geometry for accurate profiles and repeatable results

The rhombic geometry in the ISO DNMG150404 outline, together with a 55° major cutting angle and 0° clearance, produces a predictable cutting direction and positive chip flow for many turning tasks. The 0.4 mm nose radius delivers tight profile control for finishing passes and reliable corner strength during roughing, while the double‑sided chipbreaker assists in managing small chips and surface integrity. The insert thickness of 4.76 mm and the 15 mm nominal size ensure compatible seating in standard DNMG holders; compatibility to the respective holder is determined by form, clearance angle, tolerance class, fastening, size and thickness.

Process reliability and application guidance

Designed for external and internal turning, the insert performs best in stable to lightly interrupted cuts; the T6215 grade accepts moderate cutting forces while preserving edge integrity. Selection of the chipbreaker style should match the workpiece stability, feed and depth of cut to control chip shape and evacuation. The system approach — insert, appropriate outside holder or boring bar, backing shim/clamp set and replacement screws — ensures secure clamping and repeatable indexability. When machining less stable setups, consider a coarser chipbreaker or modified cutting parameters to avoid vibration and to extend insert life.

Economic advantages and order references

Standardised ISO fitment enables fast insert changes and straightforward stocking across multiple machines, supporting efficient tool management and lower inventory complexity. Consistent edge behaviour from the coated grade helps achieve repeatable surface finishes and reduces the frequency of re‑grinding or replacement. Relevant identifiers for procurement are manufacturer article number 6875524 and SKU TUN6875524, which facilitate quick checks against master data and ensure the correct original Tungaloy item is supplied.

FAQ

Which materials is this insert designed for?
The DNMG150404 T6215 insert is formulated primarily for machining stainless steels; the T6215 grade and CVD coating focus on wear resistance and controlled chip formation when turning rostfreier Stahl under stable to lightly interrupted conditions.

What is the meaning of the ISO designation DNMG150404?
The ISO DNMG150404 code describes the rhombic insert shape, the 15 mm size and the 0.4 mm nose radius; these standard dimensions ensure interchangeability with holders that accept the DNMG format.

Is the insert reversible and how many cutting edges are available per insert?
The insert is double‑sided with a chipbreaker on each cutting edge, allowing indexable reversal to extend usable life and maintain consistent cutting geometry throughout multiple indexings.

Which holders are compatible with this insert?
Compatibility depends on holder form, clearance, tolerance class, fastening, size and thickness; use holders designed for the ISO DNMG150404 format and check that the 4.76 mm thickness and cylindrical hole type match the clamping system.

How should the chipbreaker be chosen for different turning tasks?
Select the chipbreaker based on workpiece material, rigidity of the setup and desired surface finish; the double‑sided chipbreaker on this insert suits a broad range of conditions, but more aggressive chip control may be required for unstable set‑ups or heavy interrupted cuts.
