DNMG150412 T9215 Turning Insert – CVD-coated carbide, 55° rhombic (Tungaloy)

The DNMG150412 T9215 is an ISO-standard indexable turning insert designed for external and internal turning, offering a balance of wear resistance and fracture toughness for productive medium-steel machining.

• CVD-coated carbide grade T9215
• 55° rhombic shape with 1.2 mm corner radius
• Double-sided design with cylindrical hole
• 4.76 mm plate thickness for stable clamping

Consistent productivity for medium-steel turning

The CVD-coated carbide composition of this insert, grade T9215, is engineered to deliver high productivity in continuous to slightly interrupted cuts. The coating improves abrasion resistance and heat tolerance, which translates into longer tool life and fewer indexings. Specified as an ISO-standard indexable plate, the insert supports stable machining cycles and reliable chip control under typical workshop conditions, reducing unplanned downtime and improving throughput.

Geometry that ensures stable cutting and surface quality

The 55° rhombic form combined with a 1.2 mm corner radius provides a compromise between strength and finish quality: the smaller nose radius supports a better surface on light finishing passes, while the robust geometry resists edge chipping during heavier cuts. The rhombic outline and double-sided construction mean economical use of the insert, while the cylindrical hole and 4.76 mm plate thickness ensure repeatable clamping and vibration damping in the toolholder, improving dimensional consistency across production runs.

System compatibility and practical assembly guidance

As an ISO-conforming plate, compatibility with the holder depends on the insert form, clearance angle, tolerance class, fastening method, size and thickness. The recommended system comprises the insert, a matching external holder or boring bar, a shim or clamping set, and replacement screws. Selecting the correct chipbreaker and grade for the workpiece material and machining stability is essential; for medium steels the T9215 grade typically balances wear resistance and fracture safety to support continuous production.

Operational benefits and economical machining

Using this indexable plate reduces overall tooling costs by extending time between replacements and by enabling predictable performance across batches. The carbide substrate with CVD-coated surface supports consistent edge life and steady chip formation, which simplifies downstream operations such as part cleaning and inspection. For shops targeting low variation and repeatability, the technical specifications of the insert contribute to fewer process interruptions and improved part quality.
