DCMT11T304 T9225 Tungaloy — ISO rhombic turning insert for medium-to-heavy steel machining

A DCMT11T304 Tungaloy insert designed for ISO-standard external and internal turning, combining universal toughness with straightforward toolholder compatibility.

• ISO rhombic 55° geometry
• CVD-coated carbide grade T9225
• 0.4 mm corner radius for robustness
• Cylindrical hole + countersink (40°–60°)

Reliable geometry and straightforward compatibility for production use

The ISO-standard shape and rhombic 55° geometry offer a balance between accessibility and cutting stability, especially where fluctuating engagement occurs. The specified 7° relief angle and standard tolerances determine compatibility with a wide range of external holders and boring bars; this reduces setup time and simplifies inventory management. Integration is achieved through form, size and thickness conformity, ensuring consistent seating and repeatable tool life.

Durable grade and coating for heavier steel operations

The grade T9225 is a CVD-coated carbide formulated as a robust universal option for medium-to-heavy steel turning. Its composition prioritises toughness to withstand light interruptions and variable chip loads while the coating improves wear resistance and thermal stability. The single-sided chipbreaker manages swarf formation for many turning tasks, and the 0.4 mm corner radius contributes to a resilient cutting edge without excessive load on the tool. The insert’s 3.97 mm thickness and central cylindrical hole + countersink deliver secure clamping and stable performance during demanding cuts.

Practical selection advice to maintain process security

For predictable results, pair this indexable insert with a matched holder and appropriate clamping set; the hole style and size influence screw choice and seating. Selection of chipbreaker and grade should reflect workpiece rigidity and feed strategy: when interrupted cuts, variable engagement or higher depths of cut are expected, the universal toughness of this grade supports process reliability. The design reduces the need for frequent tool changes, aiding continuous production and lowering downtime risk.
