DNMG150408 T9225 DNMG — ISO turning insert (CVD‑coated carbide, 0.8 mm radius) by Tungaloy

The DNMG150408 T9225 is an ISO‑indexable turning insert designed for external and internal turning, engineered to provide reliable chip control and toughness for interrupted cuts in medium to heavy steel machining.

• CVD‑coated cemented carbide grade T9225
• Robust for medium to heavy steel machining
• Double‑sided insert with cylindrical hole
• 0.8 mm corner radius for versatile profiling

Consistent productivity through a proven grade and coating

The combination of a CVD‑coated surface on a cemented carbide substrate ensures a predictable balance between wear resistance and toughness. This grade is formulated as a robust universal grade, intended for medium to heavy steel applications where engagement conditions vary or cuts are intermittently broken. The beneficial outcome is extended tool life and fewer unexpected insert changes, which supports stable production runs and predictable machining costs.

Geometry engineered for repeatable part quality

A 0.8 mm corner radius and the classic 55° lead angle of the rhombic DNMG form promote smooth entry and stable cutting forces, resulting in improved surface finish and dimensional stability. The double‑sided design doubles the available cutting edges, lowering cost per edge and simplifying inventory. The cylindrical hole and standard ISO form ensure secure clamping when the correct holder, shim and fastening are used, minimising vibration and maintaining repeatable results across batches.

Grade characteristics that cope with interrupted and variable cuts

The T9225 composition combines a wear‑resistant coating with a substrate tuned for impact resistance. This makes it particularly suitable for applications with slight interruptions or variable engagement depths, where pure hard grades would risk chipping. The insert therefore supports efficient metal removal while reducing the likelihood of edge fracture, helping to keep cycle times stable and finishing operations predictable.

Practical compatibility and system considerations for rapid setup

Compatibility with toolholders depends on the insert form, clearance angle, tolerance class, fastening style, size and thickness; attention to these factors ensures correct seating and optimal performance. The complete system typically comprises the ISO insert, a matching external holder or boring bar, a shim/clamping set and replacement screws. For workshops aiming to streamline tooling, this insert integrates readily into standard ISO systems and supports straightforward stocking and re‑indexing practices.

FAQ

What machining tasks is this insert best suited for?
The DNMG150408 T9225 insert is designed for turning operations, especially medium to heavy steel machining and interrupted cuts where the T9225 grade offers a balance of wear resistance and toughness.

Is the insert indexable on both sides?
Yes, the DNMG150408 T9225 is double‑sided, providing multiple usable edges to reduce tooling cost per edge and simplify inventory management.

Which holder features must be checked for correct compatibility?
Compatibility requires matching the insert form, clearance angle, tolerance class, fastening type, overall size and thickness to the holder and clamping components used with the DNMG150408 T9225.

Can this grade handle high cutting speeds?
The T9225 grade is optimised for robust, variable cutting conditions rather than extreme high‑speed finishing; it performs reliably in medium to heavy steel turning with occasional interruptions.

How does the 0.8 mm corner radius affect part quality?
A 0.8 mm radius provides a balance between edge strength and profile definition, improving surface finish and dimensional stability while resisting edge chipping during variable engagement.
