DPMT070202 T9225 indexable turning insert for medium-to-heavy steel — Tungaloy

A DPMT070202 T9225 indexable turning insert in ISO‑standard rhombic 07 form, designed for reliable external and internal turning under variable engagement and light interruptions.

• CVD-coated cemented carbide grade T9225
• For medium-to-heavy steel turning
• Rhombic 07 form, 11° clearance
• 0.2 mm corner radius with cylindrical hole

Increased process reliability through tougher grade and coating

The combination of a CVD-coated finish on a cemented carbide substrate and the T9225 grade is engineered for consistent performance where contact conditions vary. The coating reduces flank wear and extends edge life, while the tougher substrate offers improved resistance in interrupted cuts and heavier engagement, making the insert suitable for medium-to-heavy steel machining. This balance of wear protection and toughness results in fewer indexings and less tool-change downtime, improving net productivity on batch and single‑piece flows.

Geometry and holder compatibility that simplify integration

The rhombic 07 shape with an 11° clearance and 0.2 mm corner radius provides a versatile cutting geometry that is compatible with a wide range of ISO holders. Compatibility is determined by the insert form, clearance angle, tolerance class, fastening method, size and thickness; these factors should be matched to the toolholder and machining task. The insert is supplied with a cylindrical hole and one-sided countersink (40°–60°) for secure clamping. Clear identification of these features ensures the correct seating and repeatable positioning in external holders or boring bars.

Practical advantages for workshop decision‑making

Using this ISO insert reduces setup complexity and supports predictable component quality. The single‑sided chipbreaker is optimised for common steel grades and helps control chip flow in turning operations, lowering the risk of entanglement and improving surface finish. For operations seeking economic longevity, the T9225 grade delivers a reliable compromise between wear resistance and edge toughness, thereby lowering the frequency of insert changes and contributing to a steadier overall machining cost per part.

FAQ

What materials is this insert best suited for? This insert is specified for medium-to-heavy steel machining; the T9225 grade and CVD-coated surface are tuned to deliver toughness and wear resistance in steel turning.

How does the chipbreaker influence performance? The single-sided chipbreaker on the insert promotes controlled chip formation in turning operations, improving surface finish and reducing risk of chip-related disturbances during cutting.

How to ensure compatibility with a toolholder? Compatibility depends on insert form, clearance angle, tolerance class, fastening, size and thickness; match these parameters to the holder specifications to ensure correct seating and secure clamping of the insert.

Is the coating beneficial for interrupted cuts? Yes—the CVD-coated layer combined with the tougher substrate reduces edge breakage and improves resilience during light interruptions or variable engagement, extending usable edge life.
