DNMG 150404 T9215 – ISO turning insert for medium steel, Tungaloy

The DNMG150404 T9215 is an ISO-standard rhombic turning insert engineered for external and internal turning operations, offering a balance of wear resistance and fracture toughness for continuous to lightly interrupted cuts.

• Tungaloy CVD-coated carbide T9215
• High wear resistance and fracture toughness
• Double-sided chipbreaker, rhombic insert
• 0.4 mm corner radius, 55° cutting angle

Consistent productivity for medium steel turning

The CVD-coated carbide grade T9215 is formulated to deliver high wear resistance while retaining sufficient toughness for demanding production runs. In practice, this means fewer index changes and longer tool life under continuous cutting conditions, which translates directly into improved machine uptime. The cutting material is optimised for medium-strength steels and performs reliably under slightly interrupted cuts, enabling higher feed rates and sustained throughput without compromising edge integrity. This technical pairing supports predictable tool-change intervals and more stable process planning on the shop floor.

Geometry that ensures repeatable part quality

The rhombic DNMG shape with a 55° cutting angle and 0.4 mm corner radius combines accessibility for external and internal contours with a cutting-edge geometry that helps produce consistent surface finishes. The insert is manufactured to ISO-standard dimensions and features a cylindrical centre hole for secure clamping. Compatibility with a holder depends on the insert form, relief angle, tolerance class, clamping method, size and thickness; these parameters are decisive for repeatable positioning and concentricity. Explained simply, matching the insert to a correctly rated external holder or boring bar reduces vibration and supports tighter dimensional control on turned components.

System-level efficiency and practical selection guidance

Operational efficiency is achieved by considering the full tooling system: indexable insert, compatible external holder or boring bar, underlay/clamp set and replacement screws. The double-sided chipbreaker increases usable edges per insert and helps control chip form, easing evacuation and reducing the risk of re-cutting. For applications with limited rigidity choose a chipbreaker and grade that favour smoother chip flow; for stable setups the T9215 grade enables more aggressive cutting parameters. Advice on selecting the appropriate chipbreaker and matching the insert to machine dynamics supports predictable cycle times and fewer interruptions for rework or tool changes, improving overall process economy.
