DCMT 11T308 T9215 — Tungaloy ISO rhombic turning insert for medium steel, CVD-coated carbide

A DCMT11T308 T9215 ISO rhombic turning insert engineered for external and internal turning of medium-strength steels, offering a balance of wear resistance and fracture safety in continuous to slightly interrupted cuts.

• CVD-coated carbide grade T9215
• Optimised for medium steel turning
• ISO rhombic insert, 11 mm size
• 0.8 mm corner radius, 7° clearance

Consistent cutting performance through CVD-coated carbide grade T9215

The T9215 grade combines a CVD-coated carbide substrate with a wear-resistant surface layer to extend tool life in demanding turning operations. CVD (chemical vapour deposition) coating forms a dense, adherent layer that reduces flank and crater wear, which translates to longer intervals between indexings and fewer unscheduled tool changes. For operations that require continuous high throughput or occasional slight interruptions, this composition provides a dependable mix of abrasion resistance and fracture toughness, helping to maintain cycle times and consistent dimensional results.

Secure clamping and standardised geometry reduce setup time

Built to the ISO rhombic profile with an 11 mm size and a 0.8 mm corner radius, the insert offers repeatable seating and clamping behaviour in compatible holders. The 7° clearance angle and a plate thickness of 3.97 mm ensure geometric stability under load, while the cylindrical hole with single-sided countersink (40°–60°) supports positive positioning and uniform clamp force. Because compatibility is determined by form, clearance angle, tolerance class, clamping method, size and thickness, using ISO-standard geometry simplifies tool procurement and reduces setup time across different machines and toolposts.

Practical system benefits for productivity and process stability

The one-sided chipbreaker and the grade’s design make the insert particularly suited to medium steel turning applications, delivering improved chip control and surface finish in many production contexts. The cutting system is straightforward: indexable insert, matching external holder or boring bar, underlay/clamp set and spare screws — a configuration that supports fast changeovers and consistent repeatability. By choosing a coated carbide solution with fracture resistance, shops gain both the productivity of extended cutting intervals and the process stability needed for reliable batch manufacturing.

FAQ

What materials is this insert designed for?
The DCMT11T308 T9215 insert is optimised for medium steel machining; the T9215 grade pairs CVD-coated carbide with fracture-resistant properties for reliable cutting performance.

How does the 0.8 mm corner radius affect machining results?
A 0.8 mm corner radius balances strength and finish: it improves edge robustness under load while maintaining a good surface finish in turning operations with the DCMT11T308 insert.

Is the insert compatible with standard ISO holders?
Yes, the ISO rhombic geometry (11T308) and the specified dimensions support compatibility with ISO-standard holders, provided the holder matches the form, clearance angle, tolerance class, clamping method, size and thickness.

What is the purpose of the cylindrical hole and countersink?
The cylindrical hole with a single-sided countersink (40°–60°) provides positive location and uniform clamp force, enhancing repeatable seating and reducing the risk of movement under cutting forces.

Which chip control features are included?
The insert features a one-sided chipbreaker tailored to medium steel turning, promoting controlled chip formation and improved surface quality during continuous to slightly interrupted cuts.
