DNMG150404 T9225 – ISO rhombic turning insert, CVD-coated carbide, 55° by Tungaloy

A DNMG150404 T9225 indexable insert designed for external and internal turning across a wide range of steel machining tasks, offering a balanced combination of toughness and wear resistance.

• CVD-coated carbide for robust steel machining
• Universal T9225 grade for medium to heavy cuts
• Rhombic DNMG geometry with 55° cutting angle
• Double-sided chipbreaker and central cylindrical hole

Consistent performance for medium to heavy steel turning

The CVD-coated carbide substrate and universal T9225 grade provide a stable cutting edge for variable machining conditions, especially where interrupted cuts or fluctuating engagement depths occur. This combination favours long tool life under demanding conditions while maintaining cutting security; the result is fewer insert changes and a smoother production flow. The double-sided chipbreaker contributes to improved chip control and reduces the risk of built-up edge, which improves surface finish and repeatability in serial turning operations.

ISO compatibility that speeds up setup and reduces uncertainty

Designed to the ISO designation 150404, this rhombic format simplifies toolholder selection and bench planning. Compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness; specifying the DNMG family ensures a predictable fit in appropriately rated external holders or boring bars. For shops standardising on ISO tooling, the predictable geometry reduces set-up time and minimises the risk of incorrect clamping—both practical savings in production environments.

Geometry engineered for strength and edge life

A 55° cutting geometry combined with a 0.4 mm corner radius and a plate thickness of 4.76 mm balances edge robustness with acceptable cutting forces. The rhombic shape and the central cylindrical hole support secure clamping, enabling consistent repeatability and the option of flipping the insert for continued use. These geometric choices help to distribute cutting stresses, increase wear resistance and maintain dimensional stability when turning shafts, shoulders or bore profiles.

Application guidance and selection tips for reliable results

Suitable primarily for steel machining in medium to heavy operations, the insert performs well when paired with a matching chipbreaker and an appropriate coolant strategy. For interrupted or unstable cuts, select a more tenacious grade and a chipbreaker designed for heavy chip loads; for finishing, combine the insert with a finer clearance and optimised cutting parameters. The ISO-format insert integrates into standard tool systems; ensure holder compatibility by confirming clearance angles and tolerance classes before mounting to secure consistent performance.

FAQ

What materials is this insert suitable for? This insert is designed for steel machining; the T9225 CVD-coated carbide grade is intended for medium to heavy turning work in steel.

Can the insert be used on internal and external turning operations? Yes, the DNMG geometry and the rhombic format support both external and internal turning applications when mounted in a suitable holder.

How does the 0.4 mm corner radius affect cutting? A 0.4 mm radius increases edge strength and improves resistance to chipping, making it suitable for heavier cuts while maintaining reasonable surface quality.

Is the insert reversible or double-sided? The insert features a double-sided chipbreaker and a central cylindrical hole, allowing it to be indexed for extended use and stable clamping.

Which item number should be referenced when ordering? Reference article number 6780870 or Manufacturer SKU TUN6780870 when specifying this Tungaloy DNMG150404 T9225 turning insert.
