DPMT 070208 T9225 – ISO rhombic turning insert by Tungaloy, CVD‑coated carbide

DPMT 070208 T9225 is an ISO‑standard rhombic turning insert optimised for medium‑to‑heavy steel turning and variable engagement conditions

• Rhombic ISO insert DPMT 070208
• CVD-coated carbide grade T9225
• Single-sided chipbreaker for steel
• 11° clearance, 0.8 mm corner radius

Consistent cutting performance for variable turning conditions

The CVD‑coated carbide grade T9225 is formulated as a robust universal grade for medium‑to‑heavy steel turning, providing increased toughness where interrupted cuts or changing engagement occur. The coating improves wear resistance without sacrificing fracture toughness, which means longer service intervals and fewer unexpected tool changes. By combining the grade with a well‑designed single‑sided chipbreaker, the insert aids in predictable chip formation and evacuation, reducing the risk of workpiece damage and helping to maintain cycle times in recurring production runs.

Geometry and clamping features that support repeatable results

Engineered as a rhombic insert with a 0.8 mm corner radius and 11° clearance, the geometry balances strength at the cutting edge with accessibility for finishing passes. The insert is ISO‑standard, so compatibility with suitable external holders or boring bars is determined by form, clearance, tolerance class, fastening style, size and thickness — all standardised elements that permit straightforward tool selection. The cylindrical hole with a single‑side countersink (40°–60°) ensures secure clamping and correct seat orientation, which contributes to repeatable positioning and stable machining, especially on heavier sections or when tool overhang is unavoidable.

Practical handling and machining efficiency in daily use

With a plate thickness of 2.38 mm and the proven Tungaloy grade, the insert combines strength with ease of indexation. The single‑sided chipbreaker simplifies tool setup and is adaptable to both external and internal turning applications. The modest corner radius promotes edge resilience while allowing productive cutting parameters; this helps to lower tooling costs per part and improves process stability. For workshops aiming to balance productivity with predictable tool life, the insert offers a durable solution that reduces downtime and supports consistent surface finishes on steel components.

FAQ

Which holder types are compatible with this insert?
Compatibility depends on holder form, clearance, tolerance class, fastening and insert size; the DPMT 070208 T9225 is ISO‑standard and fits holders designed for DPMT‑type rhombic inserts of size 07.

What materials is the insert suitable for?
The T9225 grade is a universal, robust carbide suited for medium‑to‑heavy machining of steel; it performs well under varying engagement and slightly interrupted cuts.

Why does the insert have a countersunk hole?
The cylindrical hole with a single‑side countersink (40°–60°) provides secure, repeatable clamping and correct seating in indexable toolholders, enhancing stability during turning with the DPMT 070208 T9225 insert.

Can the insert be used for internal turning?
Yes; the insert’s rhombic form and chip control features make it suitable for both external and internal turning applications when paired with the appropriate boring bar or holder.
