DNMG150408 T9215 indexable turning insert — 55° rhombic, CVD‑coated carbide by Tungaloy

DNMG150408 T9215 is an ISO‑standard rhombic indexable insert designed for external and internal turning in medium‑grade steels, combining abrasion resistance with reliable toughness.

• ISO rhombic insert DNMG150408 T9215
• CVD‑coated carbide for high wear resistance
• 55° lead angle, 0° clearance angle
• 0.8 mm corner radius, double‑sided chipbreaker
• Compatible with ISO turning holders (with hole)

High productivity for medium‑steel turning through robust grade and coating

The CVD‑coated carbide composition of this grade T9215 is specified for mid‑range steel machining, where a balance of wear resistance and fracture toughness is essential. Its microstructure and coating are selected to withstand continuous to lightly interrupted cuts, so material removal rates can be increased without a proportional loss in tool life. By combining a dependable coating system with a mechanically sound carbide substrate, the insert supports stable process performance and predictable tool‑change intervals.

Geometry that stabilises cut and improves surface quality

The rhombic form with a 55° lead angle and 0° clearance angle provides a compact cutting geometry that reduces radial cutting forces while enabling access in profiling and general turning operations. The 0.8 mm corner radius contributes to improved edge strength and consistent surface finish when finishing or semi‑finishing. As a double‑sided component with a central cylindrical hole, the plate can be indexed to use both cutting edges, extending service life and lowering per‑part tooling costs. The 4.76 mm plate thickness and 15 mm nominal size ensure compatibility with standard ISO holders designed for this format.

System compatibility and practical selection advice for reliable machining

Compatibility with a given holder is determined by form, free angle, tolerance class, fastening method, size and thickness; the ISO conformity of this insert simplifies selection for existing tool systems. The indexable insert is supplied as part of a system that includes a suitable external holder or boring bar, underlay/shim and clamping screws — correct assembly and clamp torque are decisive for repeatable results. Choose the double‑sided chipbreaker and grade pairing that matches the workpiece material and stability of the set‑up to unlock the best combination of productivity and component quality.

FAQ

What materials is this insert suited for? The DNMG150408 T9215 insert is optimised for medium‑grade steel machining; the T9215 grade was designed to combine wear resistance with fracture toughness for productive steel turning.

Can the insert be indexed to use multiple cutting edges? Yes, the insert is double‑sided and can be indexed to present fresh cutting edges; the rhombic form and central cylindrical hole enable secure clamping and edge rotation.

Which holder types are compatible with this plate? Compatibility is determined by ISO form, size, thickness and fastening; the DNMG150408 format fits standard ISO turning holders specified for DNMG‑style inserts.

How does the 0.8 mm corner radius affect finish and strength? A 0.8 mm corner radius increases edge strength for interrupted cuts and supports a consistent surface finish during finishing and semi‑finishing passes.

Is the T9215 grade suitable for light interruptions and higher cutting speeds? The T9215 grade, with its CVD coating and carbide substrate, is intended for continuous to lightly interrupted cuts and supports higher productivity in medium‑steel applications.
