DCMT 11T308 T9215 Turning Insert — rhombic 11, CVD-coated by Tungaloy

The DCMT11T308 is a rhombic ISO indexable insert designed for external and internal turning in medium-steel applications, offering high wear resistance and stable cutting performance.

• CVD-coated carbide for medium steel
• Rhombic geometry, size 11 for versatility
• 7° relief angle for secure cutting
• Cylindrical hole with 40°–60° countersink

Higher productivity through wear-resistant grade and coating

The CVD-coated T9215 grade combines high wear resistance with fracture toughness, making it a cost-effective choice for continuous to slightly interrupted turning in medium steel. The CVD-coated carbide surface reduces flank and crater wear, enabling longer tool life and more consistent component tolerances under sustained cycles. For production planners this translates into fewer indexings per batch and improved machining uptime, while operators benefit from predictable performance at raised cutting speeds. Technical terms such as CVD (chemical vapour deposition) refer to a thin, uniform coating layer that enhances hardness and temperature resistance during cutting.

Stable cutting geometry that improves surface finish

The rhombic insert form with an included angle of 55°, a 0.8 mm corner radius and a one-sided chipbreaker delivers controlled chip formation and reduced vibration. The 7° relief angle ensures the cutting edge disengages cleanly, lowering rubbing and heat generation at the flank face. Together these features help achieve a reliable surface finish and dimensional stability, especially when turning long or slender components. The cylindrical hole with a single-sided countersink (40°–60°) provides consistent clamping and repeatable seating in ISO-compatible toolholders, which supports reproducible results in series production.

ISO compatibility and system advantages for workshop efficiency

As an ISO standard turning insert, this item integrates into established systems: the insert, an appropriate external holder or boring bar, a shim/clamp kit and replacement screws form the complete tooling assembly. Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness, so stock management is simplified when holders are matched to ISO plates. The clear specification of thickness (3.97 mm) and size (11) aids ordering and inventory control. Using standardised inserts reduces tooling changeover time and supports consistent process chains on multi-shift production lines.

FAQ

What materials is this grade optimised for? The T9215 grade on the DCMT11T308 is optimised for medium steel, offering a balance of wear resistance and toughness suited to productive turning operations.

Can the insert be used for interrupted cuts? Yes — the insert is suited to continuous and light interrupted cuts; for severe interruptions a heavier-duty grade or geometry should be considered.

Which toolholders fit this insert? ISO-standard turning holders that match the rhombic form, relief angle, tolerance class, fastening and size will be compatible with this insert.

How does the hole and countersink affect clamping? The cylindrical hole with a one-sided 40°–60° countersink provides secure seating and reliable clamping when used with the correct screw, shim and clamp arrangement.
