DCMT11T308 11T308 T5115 Indexable Turning Insert – Tungaloy (Turning)

A DCMT11T308 indexable turning insert engineered for external and internal turning, optimised for cast-iron applications and ISO-holder compatibility.

• CVD-coated carbide grade T5115
• ISO rhombic insert DCMT 11T308
• 0.8 mm nose radius for precise turning
• Single-sided chipbreaker with countersunk hole

Consistent, productive performance for cast-iron turning

The DCMT11T308 is specified as a universal grade for cast iron, combining a CVD-coated surface with a wear-resistant carbide substrate to extend tool life and reduce downtime. This balanced grade offers a compromise between flank-wear resistance and edge stability, which translates into predictable tool life and less frequent tool changes. The result is improved machine utilisation and a smoother production flow when machining cast components where repeatable results are critical.

Designed for precise geometry and ISO compatibility

Compatibility is defined by form, relief angle, tolerance class, fastening, size and thickness; this insert follows ISO standards for rhombic turning plates. The plate geometry features a rhombic shape with an included angle of 55°, a 0.8 mm nose radius and a relief angle of 7°, all of which support controlled cutting forces and reliable engagement in both external and internal turning operations. These measurable parameters simplify holder selection and ensure repeatable set-up across different machines and fixtures.

Enhanced chip control and edge stability for safer cycles

The single-sided chipbreaker is matched to the T5115 grade and the insert geometry to promote consistent chip formation and evacuation when turning cast iron. Efficient chip control reduces rework and tool interference, while a CVD coating improves thermal stability at elevated cutting speeds. Together, these features lower the risk of edge chipping and allow for more stable cycles, which is especially beneficial in batch production and automated turning environments.

Practical integration and handling in the workshop

The insert is supplied with a cylindrical hole plus single-side countersink (40°–60°) for secure fastening to suitable holders or boring bars. Plate thickness is 3.97 mm and the designation complies with the ISO series of indexable turning plates, aiding inventory management and replacement procedures. When selecting a holder, match form, clearance angles and tolerance class to maintain clamping reliability. If uncertainty remains about holder compatibility or cutting parameters, technical consultation can help adapt cutting data to the machining centre and material batch.
