DNMG 150616 T9225 Turning insert by Tungaloy — ISO rhombic insert, CVD‑coated carbide, 55° approach

DNMG150616 T9225 is an ISO‑standard rhombic turning insert engineered for medium to heavy steel turning, offering a robust universal grade for varying engagement conditions.

• CVD‑coated carbide grade T9225
• Universal for medium to heavy steel machining
• ISO rhombic DNMG geometry, 55° approach
• Double‑sided design with cylindrical hole

Consistent metal removal with a tough, CVD‑coated grade

The CVD‑coated carbide grade delivers a balance of wear resistance and toughness suited to medium to heavy steel turning. The coating reduces flank wear under elevated temperatures and preserves the cutting edge during intermittent cuts, so single‑edge life is extended and tool change frequency is lowered. This directly improves machine uptime and reduces process variability, making the grade a pragmatic choice where batch consistency matters.

Fit and handling that simplify tool changeover

Built to ISO dimensions, the rhombic insert fits common holders when form, clearance angle, tolerance class, fastening, size and thickness match. The standardised geometry ensures predictable seating and repeatable clamping forces, which limits misalignment and vibration. Using standard shims and clamps together with the insert and an appropriate external holder creates a compact system that is fast to index and re‑establishes cutting parameters with minimal setup time.

Geometry that benefits precision and economy

The rhombic shape with a 55° approach provides a compromise between strength and accessibility for shoulder, external and some internal turning operations. The double‑sided configuration effectively doubles usable edges, while the cylindrical hole secures positive locating and repeatability. With a plate thickness of 6.35 mm and a corner radius of 1.6 mm, this geometry supports stable cutting in heavier cuts while maintaining surface quality and dimensional control.

Process guidance for reliable productivity

Select a matching chipbreaker and cutting parameters to suit material variability and rigidity of the setup—this insert is intended for turning operations where intermittent engagement or changing cut depths require extra toughness. Where possible, favour rigid clamping and moderate feed to benefit from the grade’s wear resistance; the construction supports predictable edge life and reduced scrap rates. For complex applications, consider incremental testing of speeds and feeds to find the best balance between cycle time and tool life.
