DNMG150408 T9225 — ISO turning indexable insert by Tungaloy (CVD-coated carbide, rhombic 55°)

The DNMG150408 T9225 is an ISO-standard rhombic indexable insert designed for external and internal turning, offering a double-sided chipbreaker and a cylindrical hole for secure clamping.

• ISO-standard rhombic insert DNMG form
• CVD-coated carbide grade T9225
• Double-sided chipbreaker for efficiency
• 0.8 mm corner radius for robust edge

Consistent cutting performance for medium‑to‑heavy turning

The DNMG150408 T9225 insert combines a CVD-coated carbide substrate with a robust universal grade to deliver consistent performance in medium‑to‑heavy steel machining. The CVD coating increases wear resistance and maintains edge integrity under varying engagement conditions, while the substrate toughness reduces the risk of chipping during intermittent cuts. This balance of hardness and toughness supports longer tool life and stable surface finish, which in turn lowers downtime and replacement frequency.

Clear guidance on compatibility and installation

As an ISO-standard insert with a rhombic 55° form and a cylindrical hole, compatibility with the toolholder is determined by the insert form, relief angle, tolerance class, fastening method, size and thickness. The plate features a 0° relief angle and a double-sided chipbreaker, enabling two indexable edges per insert and straightforward indexing. Secure clamping is achieved via the cylindrical hole; selection of the correct clamp and backing pad ensures repeatable seating and correct cutting geometry, reducing assembly errors and improving repeatability on production runs.

Productivity, application advice and measurable benefits

With a 0.8 mm corner radius, the geometry offers a resilient cutting edge that copes well with interrupted cuts and variable engagement, while still delivering acceptable surface quality for many turning operations. The double-sided chipbreaker supports predictable chip control, which is especially beneficial when machining long or unstable workpieces. For shops focusing on cost-efficiency, the combination of two usable edges per insert and the T9225 grade’s adaptability to changing cutting conditions translates into fewer insert changes and improved process reliability. For special materials or highly specific feeds and speeds, consultation with Metav Werkzeuge’s technical advisers is recommended to optimise cutting data and holder selection.

FAQ

Which materials is this insert primarily intended for?
The DNMG150408 T9225 insert is primarily intended for steel machining, offering robust performance in medium‑to‑heavy turning applications.

How many cutting edges are available per insert and what is the chipbreaker type?
The insert features a double‑sided chipbreaker, providing two usable cutting edges per plate and consistent chip control for varied machining conditions.

What determines compatibility with a specific toolholder?
Compatibility is defined by insert form, relief angle, tolerance class, fastening method, size and thickness; the DNMG150408 form, 0° relief angle and cylindrical hole require a matching DNMG clamping arrangement and backing plate.

What advantages does the CVD coating bring for this grade?
The CVD-coated carbide composition of the T9225 grade improves wear resistance and edge stability, supporting longer intervals between indexing and more consistent surface quality under changing engagement.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius increases edge strength and stability, making the insert well suited to interrupted cuts and operations where robustness is preferred over the finest possible surface finish.
