DCMT070208 T9225 – ISO turning insert for medium‑to‑heavy steel, CVD‑coated (Tungaloy)

A DCMT070208 T9225 indexable insert designed for ISO‑standard turning applications, optimised for robust steel machining where varying engagement and slight interruptions require additional toughness

• CVD‑coated carbide grade T9225
• Universal grade for medium–heavy steel
• Rhombic ISO plate DCMT 07, 55° cutting angle
• Cylindrical hole with single‑side countersink

Optimised cutting performance for demanding steel turning

The combination of a CVD‑coated surface and a tough carbide substrate in grade T9225 provides a balance of wear resistance and fracture toughness that is particularly suitable for medium‑to‑heavy turning. The coating reduces flank and crater wear under elevated temperatures, while the substrate maintains edge stability during slight interruptions or variable engagement conditions. This results in more predictable tool life, fewer unscheduled indexings and improved process economics in batch or continuous production. The single‑sided chipbreaker promotes controlled chip formation, reducing the risk of chip entanglement and improving operator safety.

Straightforward compatibility and secure mounting for consistent set‑ups

ISO designation and the rhombic geometry make insert selection and holder matching straightforward: the plate form is a rhombic DCMT size 07 with a 55° cutting edge, which determines the tool path and approach angle. The insert features a cylindrical hole with one‑side countersink (40°–60°) for robust mechanical clamping; a backing pad, clamping set and correct screws complete the system. A relief angle of 7° and a plated thickness of 2.38 mm contribute to stable seating in the pocket and reduced vibration, while the 0.8 mm corner radius helps to balance edge strength with acceptable surface finish. These measurable parameters simplify tooling decisions and reduce set‑up time at the lathe.

Increased process reliability and application flexibility

When fitted into a correctly rated holder or boring bar, this insert supports both external and internal turning operations and adapts to a variety of steel grades and cutting conditions. The universal nature of grade T9225 means one stock keeping unit can cover multiple operations, lowering inventory complexity and speeding up job changeovers. Stable chip formation and consistent cutting forces lead to predictable surface quality and repeatable tolerances, which is particularly valuable in series production. For interrupted cuts or marginal rigidity, the insert’s fracture‑tough composition reduces the likelihood of edge chipping and unplanned downtime, supporting a more efficient machining cycle overall.
