DNMG 150412 T515 for turning — Tungaloy DNMG150412 T515 insert

A DNMG150412 T515 Tungaloy insert for ISO-standard external and internal turning, optimised for economical machining of cast iron with a rhombic 55° geometry.

• ISO rhombic 55° insert, cylindrical hole
• CVD-coated carbide grade T515
• Double-sided chipbreaker for cast iron
• 1.2 mm corner radius, 4.76 mm thickness

Consistent chip control for cast-iron turning

The combination of a CVD-coated carbide grade T515 and a double-sided chipbreaker delivers controlled chip formation and stable cutting across interrupted and continuous cuts in cast iron. The rhombic 55° geometry provides a reliable approach angle for a wide range of turning tasks, while the 1.2 mm corner radius helps maintain edge strength where robustness is required. This configuration supports repeatable surface quality and reduces the frequency of edge changes, contributing to predictable cycle times and lower per-part tooling costs.

ISO compatibility and secure clamping for fast tool changes

Built to the ISO dimensions of the DNMG family, the insert matches standard holders when the form, relief angle, tolerance class, fixing method, size and thickness align. The cylindrical hole facilitates positive clamping with many outside holders and boring bars, simplifying tool setup and replacement. Clear conformity to ISO standards allows workshops to keep spare holders and pads interchangeable, minimising downtime and streamlining inventory management.

Economic productivity through modern substrate and coating

The Tungaloy specification uses a carbide substrate with a T515 coating designed for economical machining of cast iron: improved wear resistance and consistent edge stability extend usable life while keeping running costs competitive. Being double-sided offers two indexed cutting edges per insert, doubling the serviceable edges compared with single-sided types and improving overall cost-efficiency. The carbide construction ensures robustness when machining heavier sections or when encountering minor interruptions.

Practical guidance for best results

Intended for both external and internal turning, this insert performs best when the chipbreaker and grade selection match machine stability and the nature of the cut. For unstable set-ups or fine finishing, a lighter approach and reduced depth of cut preserve surface quality; for interrupted cuts or heavier machining, the 4.76 mm thickness and robust geometry deliver the required edge support. Keep tooling and clamping interfaces clean and within tolerance to ensure the ISO compliance translates to secure seating and consistent cutting performance.
