DCMT11T304 T5115 Turning Insert (ISO 11T304) – CVD-coated carbide, 0.4 mm radius | Tungaloy

DCMT11T304 is an ISO rhombic turning insert designed for general cast-iron turning with a single-sided chipbreaker and cylindrical hole for secure clamping

• CVD-coated carbide for extended tool life
• Universal grade optimised for cast iron machining
• 0.4 mm nose radius for fine finishing passes
• Cylindrical hole with single-side countersink for clamp fit

Boosted wear resistance and stable cutting performance

The CVD-coated carbide composition of this indexable insert delivers enhanced wear resistance while maintaining a robust cutting edge, characteristics that translate into longer tool life and fewer interruptions for tool changes. The T5115 grade is specified as a universal choice for cast iron, offering a reliable compromise between abrasion resistance and edge stability; this makes the insert particularly suitable where consistent surface quality and predictable tool wear are required. Explaining briefly: CVD (chemical vapour deposition) applies a hard coating layer that reduces flank wear and improves resistance to built-up edge, so customers unfamiliar with coatings can expect improved durability compared with uncoated grades.

Precise geometry for secure mounting and predictable results

Designed within the ISO rhombic form, the insert's dimensions and tolerances ensure compatibility with standard holders when the correct form, clearance angle, tolerance class, fastening method, size and thickness are observed. The cylindrical hole with a single-side countersink (40°–60°) facilitates stable clamping on most ISO-compliant toolholders, reducing the risk of movement under cutting loads. The 7° clearance angle and included 55° geometry support a balanced entry and effective chip flow, while the 3.97 mm thickness contributes to insert rigidity. Those looking to integrate the plate into existing tool setups will benefit from recognising that holder selection and correct clamp torque are decisive for repeatable performance.

Versatile use in external and internal turning, with practical machining advantages

The single-sided chipbreaker profile and 0.4 mm nose radius promote controlled chip formation and a fine surface finish during finishing or semi-finishing cuts, especially in cast-iron components. The indexable design reduces setup time and inventory complexity compared with brazed tools, enabling faster insert changes and lower overall machining downtime. For roughing, pairing the insert with a more robust chip control or a heavier nose radius is advisable; for finishing, this configuration excels at delivering consistent topography. The combination of ISO conformity and the universal T5115 grade supports versatile deployment across job-shop and production environments, improving process reliability and contributing to predictable cost-per-part metrics.

FAQ

Which materials is this insert best suited for?
The DCMT11T304 T5115 insert from Tungaloy is a universal grade optimised for cast iron applications; the CVD-coated carbide composition balances abrasion resistance and edge stability for consistent performance.

How does the T5115 grade influence tool life and surface quality?
T5115 provides a compromise between wear resistance and cutting-edge robustness; in practice the T5115 grade helps extend tool life while maintaining a predictable surface finish on cast-iron components.

What must be checked to ensure holder compatibility?
Compatibility depends on the holder matching the insert's form, clearance angle, tolerance class, fastening method, size and thickness; the DCMT rhombic shape and the cylindrical hole with countersink require an appropriate ISO-compliant clamping system.

Is the insert suitable for internal turning as well as external operations?
Yes, the indexable geometry and chip control allow use in both external and internal turning, provided the holder assembly offers sufficient rigidity and access for the required cutting parameters.

How is the insert secured in the toolholder?
The insert uses a cylindrical hole with a single-side countersink to sit on the support pad and be clamped with the appropriate screw and clamp assembly, ensuring stable positioning under load.
