DNMG150408 T9215 indexable turning insert (ISO rhombic, 55°) — Tungaloy

The DNMG150408 T9215 is an ISO‑standard rhombic turning insert designed for medium‑grade steel machining, combining CVD‑coated carbide performance with a geometry optimised for productive, repeatable turning operations

• ISO‑standard rhombic insert, 55° geometry
• CVD‑coated carbide T9215 for mid‑steel
• 0.8 mm nose radius for consistent finish
• Double‑sided, cylindrical hole for secure clamping

Increased productivity through a wear‑resistant grade

The CVD‑coated T9215 grade delivers a balance of wear resistance and fracture toughness that favours sustained cutting speeds and higher material removal rates in medium‑hard steels. With fewer premature edge failures, the insert supports predictable tool life and reduced downtime, which translates into lower process costs per component. The coating technology reduces adhesion and abrasive wear; in practical terms this means longer intervals between indexings and a more stable production rhythm.

Geometry that improves surface quality and stability

A 55° lead angle in a rhombic form concentrates cutting forces favourably while the 0.8 mm nose radius helps produce a consistent surface finish with manageable cutting loads. The specified 0° clearance angle and the insert thickness ensure that seating and clamping stresses are controlled when the correct holder is selected. For operators, this geometry offers a compromise between form accuracy and edge strength, helpful when transitioning from finishing to light roughing without changing tool types.

System compatibility and cost efficiency in handling

Being an ISO insert, the component fits into standard turning tool systems when holder form, clearance angle, tolerance class, fixing method, size and thickness match. The double‑sided design and cylindrical hole permit secure clamping and two usable edges per index, improving cost efficiency per cutting edge. Select the appropriate chipbreaker and grade for the workpiece material and cutting condition; remember that the overall system includes the insert, a matching outside holder or boring bar, a support/ clamp kit and replacement screws to maintain process reliability.

FAQ

What materials is this insert suited for?
The T9215 grade is engineered primarily for medium‑grade steel machining; the DNMG150408 insert from Tungaloy offers the wear resistance and fracture toughness suitable for continuous to lightly interrupted cuts in such materials.

How does the insert geometry affect surface finish?
The rhombic 55° geometry combined with a 0.8 mm nose radius provides a good balance between cutting stability and surface quality, enabling consistent finishes without excessive cutting forces.

Is this insert reversible or single‑use per edge?
The insert is double‑sided and features a cylindrical hole for secure clamping, allowing indexing to a fresh edge and thus extending usable life per insert.

What determines compatibility with a toolholder?
Compatibility is determined by matching the insert form, clearance angle, tolerance class, fixing method, size and thickness to the holder; the DNMG150408 follows ISO dimensions, simplifying selection when holders are ISO‑compliant.

Can this insert handle interrupted cuts?
The T9215 grade is suitable for continuous to lightly interrupted cutting; for heavy interruptions, a different grade or geometry may be preferable to maximise edge life.
