DCMT 11T304 T9215 indexable turning insert by Tungaloy — CVD-coated carbide, 55° rhombic

The DCMT 11T304 T9215 is an ISO-standard rhombic indexable insert designed for external and internal turning, offering wear-resistant performance for medium steel applications.

• CVD-coated carbide grade T9215
• Optimised for medium steel machining
• 55° rhombic insert with 0.4 mm nose radius
• Cylindrical hole with 40°–60° countersink

Increased productivity through wear-resistant coating and grade

The combination of a CVD-coated surface and the T9215 carbide grade delivers elevated wear resistance while retaining good fracture toughness, which supports longer cutting intervals in serial production. For turning of medium-grade steels the insert performs well under continuous to light interrupted cuts, enabling more consistent cycle times and reduced index changes. The coating protects the substrate at elevated temperatures and reduces built-up edge formation, translating into steadier surface finishes and fewer unplanned tool changes.

Secure seating and geometry that improves process stability

The 55° rhombic geometry and 0.4 mm nose radius balance strength and finishing capability: the angle reduces radial cutting forces for stable external turning, while the modest radius maintains edge resilience for general purpose operations. The 7° relief angle ensures the insert clears the workpiece to prevent rubbing, and the standard ISO form guarantees interchangeability with compatible holders. A cylindrical hole with a 40°–60° countersink provides reliable clamping and repeatable seating, simplifying index changes and maintaining concentricity in demanding setups.

Practical selection and handling for consistent results

With a plate thickness of 3.97 mm, the insert offers sufficient stiffness for robust cuts while remaining easy to index when required. The single-sided chipbreaker supports controlled chip formation for many turning tasks; select the chipbreaker and cutting data according to material, setup rigidity and feed to get the best balance between tool life and surface quality. Compatibility depends on holder form, free angle, tolerance class, fastening and size, so confirmation of the matching holder and clamping hardware is recommended to ensure optimal performance and safe operation.

FAQ

What materials is this insert best suited for?
The insert is optimised for medium steel applications; the Tungaloy DCMT 11T304 T9215 grade and CVD-coated carbide construction provide wear resistance suitable for standard and alloy steels.

How does the 55° geometry affect cutting performance?
A 55° rhombic geometry reduces radial cutting forces and improves stability in turning operations, making the insert appropriate for general-purpose external and internal turning with a good balance between strength and finish.

What does the 0.4 mm nose radius mean for surface finish and strength?
A 0.4 mm nose radius offers a compromise between robustness and surface quality: it resists premature chipping while allowing acceptable surface finishes at typical turning feeds.

Is the insert compatible with standard ISO holders?
The insert follows ISO conventions; compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness—confirm these parameters to ensure correct seating for the DCMT 11T304 T9215.

What is the purpose of the cylindrical hole with countersink?
The cylindrical hole with a single-sided countersink (40°–60°) provides reliable clamp engagement and repeatable positional accuracy when used with the correct clamping set and screw configuration for ISO indexable systems.
