DPMT070202 T9225 — Tungaloy turning insert, rhombic 55° CVD-coated carbide

The DPMT070202 T9225 is an ISO-standard rhombic turning insert designed for external and internal turning operations, offering a universal grade optimised for interrupted and variable engagement conditions.

• ISO-standard rhombic insert, 55° diamond
• CVD-coated carbide grade T9225
• Robust for medium to heavy steel turning
• Cylindrical hole with 40°–60° countersink

Accurate cutting performance for consistent cycle times

The combination of a CVD-coated surface and the T9225 cutting grade provides a balance of wear resistance and toughness that reduces flank wear under varying engagement conditions. As an indexable insert, its coating limits adhesion and thermal degradation while the substrate maintains edge integrity during heavier cuts. This results in more predictable tool life and fewer unplanned tool changes, supporting continuous production and reduced machining variability.

Stable geometry and secure clamping for repeatable results

A 55° rhombic geometry paired with a corner radius 0.2 mm offers a compromise between edge strength and surface finish. The plate thickness 2.38 mm increases rigidity under radial loads, while the cylindrical hole with single-sided countersink (40°–60°) ensures positive seating and reliable clamping with compatible holders. Together these features decrease vibration and enable stable chip formation, which improves surface quality and dimensional repeatability on turned components.

Optimised for steel turning and flexible in application

The robust universal grade is intended primarily for steel machining in medium to heavy cuts and copes well with slightly interrupted cuts where additional toughness is required. The single-sided chipbreaker assists in controlled chip flow for many turning tasks, simplifying post-process handling. Compatibility with a holder is determined by form, clearance angle, tolerance class, fastening, size and thickness; Metav Werkzeuge can advise on matching holders and clamping sets for specific setups.

FAQ

What materials is the insert best suited for?
The Tungaloy DPMT070202 T9225 insert is optimised for medium to heavy steel turning, offering a universal balance of wear resistance and toughness suitable for variable engagement and slightly interrupted cuts.

How does the wpl geometry affect machining?
The 55° rhombic form combined with a 0.2 mm corner radius provides a compromise between edge strength and surface finish, enabling stable cutting forces and controlled chip formation during turning.

Is the insert compatible with all ISO holders?
Compatibility depends on holder form, clearance angle, tolerance class, fastening, size and thickness; the DPMT070202 conforms to ISO geometry but matching the specific holder design is required for correct seating and clamping.

What role does the T9225 coating play?
The T9225 CVD coating improves wear resistance and heat tolerance while the carbide substrate supplies toughness, making the grade reliable for longer tool life under demanding steel machining conditions.

Which feature improves clamping reliability?
The cylindrical hole with a single-sided countersink (40°–60°) is designed for secure seating and repeatable clamping, reducing the risk of movement under load and supporting consistent machining results.
