DNMG 150404 T5115 indexable insert for turning by Tungaloy — CVD-coated carbide, 55° rhombic geometry

DNMG150404 T5115 is an ISO-designation indexable insert intended for external and internal turning, optimised for cast iron machining and compatible with standard ISO toolholders

• CVD-coated carbide grade T5115
• Rhombic 55° geometry, 0.4 mm corner radius
• Double-sided chipbreaker, cylindrical hole

Increased efficiency when machining cast iron components

The CVD-coated carbide formulation of this insert delivers a balanced combination of wear resistance and edge stability, making it well suited to a broad range of grey and nodular cast iron applications. The T5115 grade is designed as a universal choice for cast iron, offering predictable tool life and consistent surface quality under typical turning conditions. The chemical vapour deposition (CVD) layer provides a hard, thermally stable barrier that reduces flank wear; in practice this translates to fewer indexings and lower tooling costs per component while maintaining dimensional accuracy.

Precise geometry for repeatable finishes and secure clamping

A 55° rhombic geometry with a 0.4 mm corner radius gives a compromise between strength and edge definition, supporting fine form work as well as medium machining passes. The insert is produced as a double-sided component with a cylindrical hole for positive location in standard clamping systems, enabling rapid and repeatable tool changes. The zero-degree relief angle promotes consistent contact conditions and stable cutting forces, which benefits cycle-time predictability and reduces the need for excessive machine adjustments. Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness — all in accordance with ISO norms.

System approach and selection guidance for productive turning

An efficient turning setup relies on the insert, a matched external holder or boring bar, a shim/clamping set and spare screws for uninterrupted operation. The indexable insert fits into this system and is intended to be paired with a holder selected for rigidity and support; the appropriate chipbreaker and grade should be chosen based on workpiece material, machining strategy and machine-tool stability. For less experienced planners, selecting a double-sided chipbreaker helps maintain chip control during interrupted cuts, while the universal T5115 grade provides a pragmatic starting point for many cast iron turning tasks. When a higher edge stability or extended life is required, consider consultation on alternative grades or coatings tailored to the process.

FAQ

What materials is this insert suitable for?
The DNMG150404 T5115 indexable insert is formulated primarily for cast iron machining; the T5115 grade offers a broad material coverage with an emphasis on wear resistance and edge stability in grey and nodular cast iron.

How does the CVD coating affect tool life?
The CVD-coated carbide surface on the DNMG150404 reduces flank wear and improves thermal resistance, which typically results in longer service intervals and more consistent surface finish when compared with uncoated grades under similar cutting conditions.

How is the insert mounted and indexed?
The insert uses a cylindrical hole and fits standard ISO-compatible clamping systems; as a double-sided component it can be indexed to present a fresh cutting edge, reducing downtime and tooling cost per part.

Is the geometry suitable for finishing passes?
The 55° rhombic geometry with a 0.4 mm corner radius provides a balanced option for finishing and medium cuts, offering both edge strength and the ability to achieve precise surface quality on turned components.

Which components are required for a complete tooling system?
A complete system comprises the indexable insert itself plus a compatible external holder or boring bar, a shim or clamping set and replacement screws; these elements ensure correct seating, rigidity and repeatable positioning for the insert.
