DCMT11T304 T9215 Tungaloy – ISO turning indexable insert for turning

DCMT11T304 T9215 is a rhombic ISO turning insert designed for medium steel machining, offering high productivity in continuous to lightly interrupted cuts

• CVD-coated carbide grade T9215
• For medium steel, high wear resistance
• Rhombic 55° insert with 7° relief
• Cylindrical hole with 40°–60° countersink

High productivity through robust grade and coating

The combination of a CVD-coating and the T9215 carbide grade delivers a balance of wear resistance and fracture toughness that supports higher machining rates while maintaining consistent edge life. This ISO-normed insert is intended for turning operations on medium steel and performs well in continuous and lightly interrupted cuts. The specification of a coated carbide substrate means the component is optimised for productive series machining where consistent performance and predictable tool life reduce process interruptions and rework.

Geometry that improves accessibility and surface finish

The rhombic 55° shape with a 7° relief provides stable cutting geometry for external profiles and internal diameters where approach angles and access are decisive. A 0.4 mm corner radius moderates cutting forces and helps deliver a controlled surface finish without sacrificing strength at the cutting edge. The plate thickness of 3.97 mm and 11 mm size offer a secure seating in matching holders; the central cylindrical hole with a single-sided countersink (40°–60°) ensures positive clamping and repeatable positioning in standard clamping systems.

Practical benefits from chip control and application range

Equipped with a single-sided chipbreaker, this insert aids chip formation and evacuation when machining steels, reducing the risk of chip-related interruptions and improving productivity. The CVD layer enhances abrasion resistance while preserving core toughness, making the grade suitable as a first choice for medium steel workpieces where a balance between tool life and productivity is required. Selecting the correct chipbreaker and grade depending on workpiece material and machine stability yields tangible cycle-time savings in routine production.

System compatibility and recommended setup

The insert forms part of a system: an ISO turning plate paired with a matching external holder or boring bar, a shim/clamping set and replacement screws. Compatibility depends on insert form, relief angle, tolerance class, fastening, size and thickness, so holders must be chosen accordingly. For best results, match the T9215 grade and the single-sided chipbreaker to the material and the stability of the setup. For users unfamiliar with holder matching, providing holder geometry, tolerance class and clamping style to technical advisors will expedite selection and reduce trial adjustments.

FAQ

What materials is this insert suitable for?
The DCMT11T304 insert in T9215 grade is optimised for medium steel machining and offers high wear resistance suitable for continuous to slightly interrupted cuts.

How does the 55° geometry affect machining?
A 55° rhombic approach provides improved access to shoulders and contouring operations; the geometry balances cutting forces and enables good surface finish performance.

What does the T9215 grade mean in practice?
T9215 is a CVD-coated carbide grade that combines abrasion resistance with sufficient toughness, making it a first choice for productive steel turning where both wear life and breakage resistance are required.

Is the insert compatible with standard ISO holders?
Compatibility requires matching form, relief angle, tolerance class, fastening, size and thickness; when these parameters align, the insert fits standard ISO holders and boring bars.

What is the purpose of the cylindrical hole with countersink?
The central cylindrical hole with a one-sided countersink (40°–60°) ensures secure, repeatable clamping and correct seat in compatible clamping systems
