DNMA 150612 T5115 ISO turning insert for external and internal turning, Tungaloy

The DNMA 150612 T5115 is an ISO-indexable turning insert designed for precision external and internal turning, optimised for machining cast iron with a balanced combination of wear resistance and cutting-edge stability.

• CVD-coated carbide grade T5115
• ISO DNMA 55° rhombic insert form
• Designed for cast iron machining

Consistent performance on cast iron with CVD-coated carbide

The CVD-coated carbide grade T5115 provides a balanced combination of wear resistance and edge stability that suits a wide range of cast iron applications. This universal grade reduces the need for multiple special-purpose grades, enabling longer tool life under typical finishing and medium-duty roughing conditions. The coating improves thermal and abrasive resistance, which helps to maintain a predictable surface finish and lowers the frequency of index changes. For manufacturers seeking reliable productivity on cast parts, the material and coating synergy supports steady cycle times and fewer unplanned interruptions.

Secure seating and stable clamping for predictable tool life

Built to ISO form standards, the rhombic DNMA geometry with a 55° approach angle and a 1.2 mm corner radius combines rigidity with accessible cutting-edge strength. Compatibility with toolholders depends on insert geometry, clearance angle (0°), tolerance class, attachment method and plate thickness; this insert features a cylindrical central hole for positive location. The 6.35 mm plate thickness and standardised size simplify holder selection and deliver improved resistance to bending and chatter in rigid setups. As a result, the cutting edge remains stable under load, supporting reproducible part quality and extending the service interval of the turning system.

Practical applications and process recommendations for turning

The insert is intended for both external and internal turning where cast iron is the primary workpiece material. As this grade is supplied without a chipbreaker, selection of cutting parameters should match machine stiffness and workpiece clamping conditions; a stable setup and tailored feed rates will enable the best performance. When encountering interrupted cuts or heavy radial depths, favour lower cutting forces and check toolholder rigidity. Coolant use and correct insert orientation further support thermal control and chip evacuation, helping to preserve edge condition and part surface integrity.

Production benefits: inventory simplification and efficient changeover

Using an ISO-standard insert such as this one reduces tooling variety on the shop floor and simplifies inventory management. The standardised form and the universal T5115 grade mean fewer SKUs to stock while still covering a broad range of cast iron tasks. Quick indexability and simple replacement procedures cut downtime during tool changes, contributing to smoother production flow and predictable throughput. For operations aiming to balance cost efficiency with process reliability, the combination of a proven carbide grade and ISO conformity delivers measurable operational advantages.

FAQ

What materials is this insert best suited for? The DNMA 150612 T5115 insert is optimised for machining cast iron; the CVD-coated T5115 grade balances wear resistance and edge stability for that material group.

Does the insert fit standard DNMA toolholders? Yes. The insert follows ISO DNMA geometry and is compatible with holders that match the specified form, 55° angle, thickness (6.35 mm) and central cylindrical hole.

Is there a chipbreaker included with this grade? This specific insert is supplied without a chipbreaker, so chip control depends on cutting parameters, workpiece material and the chosen holder or downstream chip management.

How does the 1.2 mm corner radius affect operation? A 1.2 mm corner radius increases edge strength and gives a more robust cutting edge for improved resistance to edge chipping, making it suitable for stable finishing and medium cutting conditions.

Can this insert be used for internal turning operations? Yes. The ISO DNMA form and rhombic geometry allow use in suitable internal turning holders provided the machine setup offers the required rigidity and access.
