DNMG 150412 T9215 Wendeplatten - Tungaloy

Take advantage of the CVD-coated carbide (T9215) for high wear resistance, the 55° rhombic geometry for stable cutting forces and the 1.2 mm corner radius for durable edge life in medium-steel turning; order the DNMG150412 T9215 insert directly via Metav Werkzeuge or ask our consultants for compatibility and application advice.

DNMG150412 T9215 indexable turning insert — CVD-coated carbide, 55° rhombic, 1.2 mm radius (Tungaloy)

The DNMG150412 T9215 is an ISO-format indexable insert engineered for turning applications, offering a balance of wear resistance and fracture toughness suited to medium-steel external and internal turning.

• CVD-coated carbide grade T9215
• Rhombic 55° geometry
• 1.2 mm corner radius
• Double-sided with cylindrical hole

Productive turning for medium steel with predictable tool life

This insert is built around a CVD-coated carbide substrate that combines surface hardness with a resilient substrate to resist both abrasive wear and edge chipping. As a result, machining cycles in medium steel become more consistent, reducing unplanned tool changes and improving uptime. The T9215 grade is formulated to support continuous to mildly interrupted cutting, so throughput is maintained while component tolerances remain stable. By choosing a coated carbide insert rather than a coated high-speed option, the process benefits from a favourable balance of wear resistance and fracture toughness, which is especially relevant for production environments where repeatability matters.

Secure clamping and ISO compatibility for straightforward integration

Compatibility with toolholders depends on geometric factors such as form, clearance angle and thickness; the ISO designation ensures the insert fits holders sized for DNMG150412 geometry. The 55° rhombic shape delivers a controllable cutting direction and good access in shoulder and profile work, while the cylindrical hole enables positive seating and repeatable clamping. Specifying this ISO insert simplifies tool provisioning because it adheres to established standards; maintenance teams can verify holder fit by checking form, free angle, tolerance class, fastening method, size and thickness before mounting. This clarity shortens setup time and reduces the risk of mismatch in the workshop.

Durable edge life and consistent surface finish for serial production

The combination of geometry and coating leads to extended effective cutting life: a 1.2 mm corner radius spreads cutting loads and improves edge stability, which helps to maintain surface finish over longer tool life. The double-sided design provides two usable cutting edges per index, enhancing cost-efficiency and making replacements quicker on the shop floor. For machinists requiring predictable batch quality, the insert’s design supports repeatable surface integrity and dimensional control, reducing rework and supporting higher first-pass yield in serial production.

FAQ

What materials is this insert best suited for?
The DNMG150412 T9215 insert is optimised for medium steel machining; the T9215 CVD-coated carbide combines wear resistance and toughness for continuous to lightly interrupted cuts.

How does the 55° rhombic geometry affect cutting performance?
A 55° rhombic geometry provides good access for profiling and shoulder cuts while controlling cutting forces, which helps to improve stability and surface finish when using the DNMG150412 insert.

Can the insert be used with any DNMG holder?
The ISO designation DNMG150412 ensures broad compatibility, but seating depends on holder form, free angle, tolerance class and fastening; verify these parameters against the holder before fitting.

What are the practical benefits of the double-sided design?
Double-sided construction doubles the available cutting edges, improving cost efficiency and shortening downtime by allowing a quick index change when one edge is worn.

Is the T9215 coating suitable for interrupted cuts?
The T9215 CVD-coated carbide is formulated for high productivity in continuous to mildly interrupted cutting; heavy interruptions may require a different grade or geometry.
