DCMT 11T308 T9215 — turning insert by Tungaloy (CVD‑coated carbide, rhombic 11 mm)

DCMT11T308 T9215 Tungaloy insert is an ISO‑standard rhombic turning insert designed for external and internal turning operations in medium‑steel machining.

• DCMT11T308 rhombic insert, 11 mm
• CVD‑coated carbide grade T9215
• 0.8 mm corner radius, single‑sided chipbreaker
• Cylindrical hole with 40°–60° countersink

Consistent productivity for medium‑steel turning

The combination of a CVD‑coated surface and a wear‑resistant carbide substrate (grade T9215) provides a robust solution for continuous to slightly interrupted cuts in medium‑hard steels. The coating increases resistance to abrasive wear while the substrate preserves fracture toughness, which together reduce insert change frequency and help maintain consistent cycle times. For workshops focused on throughput and repeatability, this choice supports higher machining rates without compromising edge life.

Precise fit and standardised compatibility

Compatibility with toolholders is determined by ISO form, the relief or free angle (7°), tolerance class, mounting design, size and thickness. The rhombic shape and the ISO designation ensure interchangeability across standard holders when the correct shape and clamping features are matched. Using an insert that conforms to established ISO profiles simplifies inventory and reduces setup time, while a proper fit keeps cutting geometry stable and repeatable for predictable surface finish and dimensional accuracy.

Improved chip control and edge security

The single‑sided chipbreaker and the modest corner radius (0.8 mm) balance chip formation and edge strength, which is especially valuable when machining long bars or components requiring continuous operation. Controlled chip flow lowers the risk of re‑cutting and reduces the need for complex chip management systems. The insert’s design supports safe evacuation of chips and reliable edge behaviour under steady cutting conditions, helping to protect both the workpiece and the cutting edge against unexpected forces.

System approach and practical handling

A complete cutting system comprises the insert, a matching holder or boring bar, an appropriate shim or clamp set, and replacement fixing screws; selecting the correct chipbreaker and grade according to workpiece material and machine stability is essential. The insert’s 11 mm size and 3.97 mm thickness allow straightforward accommodation in standard clamping systems that accept rhombic ISO plates. For workshops planning process layouts, choosing matching holders and clamping parts reduces vibrations and extends insert life, enabling a more economic production flow.

FAQ

What materials is this insert best suited for?
The DCMT11T308 T9215 Tungaloy insert is optimised for medium‑steel machining, combining CVD coating and a tough carbide substrate to deliver wear resistance and reliable edge life in continuous to slightly interrupted cuts.

How is compatibility with a holder ensured?
Compatibility depends on ISO form, relief angle, tolerance class, mounting type, size and thickness; verifying these parameters ensures the insert seats correctly and performs as designed.

What chip control does this insert provide?
The single‑sided chipbreaker promotes controlled chip formation and evacuation, reducing re‑cutting and supporting safer, more predictable turning operations.

Can this insert cope with interrupted cuts?
The T9215 grade offers good fracture resistance and is suitable for continuous to slightly interrupted cutting; for heavy interruptions, a different geometry or a more robust grade may be advisable.
