DCMT 11T304 T9225 indexable insert for turning by Tungaloy — rhombic, 7° clearance

The DCMT11T304 T9225 is an ISO‑standard indexable turning insert engineered for reliable performance in medium to heavy steel machining, offering a balanced mix of toughness and wear resistance.

• ISO‑standard indexable insert for turning
• CVD‑coated carbide grade T9225 for steel
• Rhombic insert, 55° included angle
• 0.4 mm nose radius and 7° clearance

Consistent cutting performance under variable conditions

The insert delivers stable results in applications where cutting conditions change or interruptions occur. Its CVD‑coated carbide substrate and the T9225 grade combine to provide improved edge stability and resistance to abrasive wear, which translates into longer tool life and fewer insert changes. For workshops seeking predictable cycle times, the geometry and coating reduce thermal degradation and maintain cutting edge integrity, helping to sustain throughput and reduce unplanned downtime.

Geometry and clamping: why compatibility matters for productivity

Designed to ISO dimensions, the rhombic shape with a 55° included angle and a 7° clearance ensures compatibility with a wide range of external holders and boring bars. Correct matching of form, clearance angle, tolerance class, fastening and thickness is critical: it secures the insert, optimises chip flow and prevents deflection during heavy cuts. The cylindrical hole with a single‑side countersink (40°–60°) ensures positive seating and repeatable clamping, contributing directly to dimensional accuracy in serial turning operations.

Material and chip control explained in plain terms

The grade is a CVD‑coated carbide, a coating process that deposits a thin, hard layer to resist abrasion and thermal effects. T9225 is formulated as a universal, tough grade suitable for varied steel types, offering a compromise between wear resistance and fracture toughness. The single‑sided chipbreaker supports discrete chip formation, which is particularly beneficial in interrupted cuts and variable engagement depths, reducing the risk of built‑up edge and easing chip evacuation from the work area.

Practical advantages for workshop planning and tool management

With a nominal size of 11 mm, a thickness of 3.97 mm and a 0.4 mm nose radius, this insert suits finishing and medium roughing passes where a small nose radius improves surface finish while retaining strength. The ISO standardisation simplifies inventory management and ensures interchangeability across compatible holders, supporting lean tooling strategies. When combined with a suitable holder and clamping set, the insert contributes to stable part quality and repeatable cycle times.
