DNMG 150404 T6215 — ISO rhombic turning insert (CVD-coated), Tungaloy

DNMG 150404 T6215 is an ISO-format rhombic insert designed for external and internal turning in ISO-compliant tool systems, optimised for stable machining of stainless steel

• CVD-coated carbide T6215
• Optimised for stainless steel turning
• Rhombic insert, 15 mm, 55° lead angle
• Double-sided geometry, cylindrical hole

Proven wear resistance for steady productivity

The CVD-coated cemented carbide grade T6215 delivers enhanced wear resistance and consistent edge life when machining stainless steel in stable or slightly interrupted cuts. The coating forms a hard, wear-resistant surface that reduces flank wear and prolongs tool life; this leads to fewer indexings and less downtime, improving overall process economy. The combination of coating and substrate ensures stable chip formation and repeatable results in series production.

Precise geometry for consistent engagement and accuracy

The rhombic shape with a 55° lead angle and 0° relief angle provides a predictable cutting direction and a low-profile seat in ISO holders, while the 0.4 mm corner radius balances edge strength with surface finish capability. The insert’s 4.76 mm thickness and standard 15 mm size ensure mechanical stability under typical turning parameters. These geometric attributes support dimensional control and help maintain surface quality during external and internal turning operations.

Practical system setup and application guidance

Compatibility with the toolholder depends on form, relief angle, tolerance class, fastening method, size and thickness; the insert is ISO-standardised for straightforward integration into existing holders or boring bars. The cylindrical hole and double-sided design permit economical reindexing and secure fastening. For best performance select a chipbreaker and grade matched to the workpiece, machining stability and feed range — the right chip control reduces heat and enhances tool life.

How to choose chipbreaker and cutting conditions

Select the double-sided chipbreaker according to material and process stability: a more aggressive chipformer for unstable conditions or a finer chipbreaker for superior surface finishes on stainless steel. Moderate cutting speeds and steady feeds help avoid built-up edge when working with corrosion-resistant alloys. For series production, pair the insert with a rigid holder, correct nose radius and stable clamping to make the most of the insert’s wear resistance and repeatable edge performance.

FAQ

What holders are compatible with this insert?
Compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; the DNMG 150404 T6215 is ISO-standard and fits holders and boring bars designed for DNMG indexes.

Which materials can be machined with this grade?
The T6215 grade on the DNMG 150404 is optimised for stainless steel and offers wear resistance suitable for stable to mildly interrupted turning operations.

How does the CVD coating benefit performance?
The CVD-coated cemented carbide substrate on the DNMG150404 T6215 provides a hard, wear-resistant surface that reduces flank wear, supports stable chip formation and extends edge life in serial turning.

Is the insert economical to use in production?
Yes; the double-sided geometry and reindexable design of the DNMG150404 T6215 reduce per-edge costs and help maintain consistent productivity and process economy.

What nose radius should be selected for surface finish?
The DNMG insert has a 0.4 mm corner radius; pairing this radius with appropriate feed and holder rigidity yields a good compromise between edge strength and surface finish.
