DNMG150412 150412 T515 indexable turning insert for turning by Tungaloy — CVD-coated carbide for cast iron

The DNMG150412 T515 is an ISO-standard rhombic indexable turning insert designed for economical external and internal turning of cast iron, offering a balance of cutting performance and process reliability

• CVD-coated carbide grade T515
• ISO DNMG rhombic shape, 55° included angle
• Double-sided chipbreaker for cast iron

Proven economy and consistency for cast-iron turning

The CVD-coated T515 carbide grade delivers a combination of wear resistance and cost efficiency that suits batch production and continuous turning operations. The CVD-coated surface improves edge life under interrupted cuts and higher temperatures, which translates into fewer index changes and better productivity. As an ISO DNMG insert, compatibility with standard external holders is ensured by the geometry and sizing, reducing setup complexity and enabling predictable cycle times on the shopfloor.

Versatile geometry that balances strength and surface finish

The rhombic DNMG shape with a 55° included angle provides a versatile cutting geometry for facing and turning operations. The 1.2 mm corner radius offers a compromise between a robust cutting edge and the capacity to achieve acceptable surface finishes; a larger radius supports heavier cuts while a smaller one favours finer finishes. The 0° rake promotes stable cutting when machining brittle materials, and the 4.76 mm plate thickness contributes to insert rigidity. The insert’s cylindrical hole and through-hole mounting provide secure clamping and accurate location in compatible tool-holders.

Practical system integration and handling benefits

As a double-sided indexable insert, the design increases usable cutting edges per insert, reducing tooling costs per component and simplifying inventory management. The insert forms part of an ISO-compliant system: matching external holders or boring bars, a suitable underlay/clamping set and replacement screws complete the assembly. Select a chipbreaker and the T515 grade according to workpiece stability and interrupt conditions to optimise both tool life and component quality. Compatibility is determined by form, clearance angle, tolerance class, fastening and plate thickness, ensuring predictable performance when integrated correctly.

Application guidance and operational advantages

For turning cast iron, the combination of T515 grade and the dual-sided chipbreaker is tailored to maintain a controlled chip flow and consistent surface quality across varying cutting depths. The robust carbide body supports higher cutting speeds compared with uncoated grades while the CVD coating helps maintain a sharp, wear-resistant edge. Where vibration or poor workholding is present, prioritise a more positive clamping arrangement and choose a chipbreaker geometry that matches the degree of interruption to preserve edge integrity and reduce part rework.

FAQ

What materials is this insert intended for?
The DNMG150412 T515 insert is optimised for machining cast iron; the T515 CVD-coated carbide grade is selected for efficient, economical performance on this material.

Will the insert fit standard ISO DNMG tool-holders?
Yes, the insert follows ISO DNMG dimensions (150412) and is compatible with standard external holders and boring bars that match form, clearance angle and plate thickness.

How does the double-sided chipbreaker affect costs?
A double-sided chipbreaker doubles the usable cutting edges per insert, lowering tooling cost per edge and simplifying inventory management while maintaining consistent chip control.

What does the 1.2 mm corner radius mean for operation?
A 1.2 mm corner radius balances edge strength and surface finish: it supports heavier cuts with improved edge life while still allowing acceptable surface quality in general turning.

Is the T515 grade suitable for interrupted cuts?
The T515 grade with a CVD coating is designed to handle interrupted cuts better than uncoated carbides, but the choice of chipbreaker and stable clamping remain important for best results.
