DNMG150612 T515 Turning insert by Tungaloy — CVD‑coated cemented carbide, 55°

The DNMG150612 T515 is an ISO‑standard rhombic indexable insert designed for external and internal turning, optimised for economical machining of cast iron with a double‑sided chipbreaker and cylindrical mounting hole

• CVD‑coated cemented carbide grade T515
• ISO DNMG150612 rhombic insert, 55° angle
• Double‑sided chipbreaker for stable chips

Consistent chip control for cast iron turning

The CVD‑coated T515 grade is developed for efficient machining of cast iron, delivering stable chip formation and predictable cutting performance. The applied coating increases abrasive wear resistance while the substrate retains toughness, which together reduce tool consumption in serial production. For operations with interrupted cuts or variable stability, the double‑sided chipbreaker promotes repeatable chip segmentation and prevents long, stringy chips that would otherwise slow down downstream processes.

Secure clamping and ISO compatibility for predictable results

The rhombic DNMG form with a 55° approach angle and a cylindrical hole ensures precise positioning in compatible toolholders and steady cutting forces. The 0° clearance angle provides a neutral geometry suitable for a wide range of turning tasks, while the 6.35 mm thickness contributes to mechanical strength under heavier engagement. Compliance with ISO dimensions simplifies toolholder selection and reduces setup time, so process planners can rely on consistent assembly and repeatable part quality.

Improved productivity through economical indexable design

Being double‑sided and manufactured from cemented carbide, the insert reduces per‑edge cost by allowing re‑indexing and extending the usable life of each unit. The CVD coating improves wear resistance at elevated cutting speeds typical for cast iron, enabling higher throughput without sacrificing surface finish. The built combination of geometry and grade helps to lower overall tooling costs while maintaining stable machining performance in production environments.

Practical guidance for selection and use

This insert is intended for standard external and internal turning; selection of chipbreaker and grade should follow considerations of workpiece stability, cut interruptions and required cutting speed. The cutting system comprises the ISO insert, a matching external holder or boring bar, a shim/clamping set and replacement screws. Compatibility with a holder depends on insert form, clearance angle, tolerance class, fixation, size and thickness — verify these parameters when replacing or upgrading tooling to ensure optimal clamping and performance.

FAQ

What materials is this insert optimised for? The DNMG150612 T515 insert is optimised for machining cast iron; the T515 grade and chipbreaker promote stable chips and economic cutting in grey and nodular cast irons.

How is the insert mounted in the toolholder? The insert uses a cylindrical centre hole and standard clamping geometry for ISO DNMG holders; mounting requires the matching holder, a shim/clamping set and the appropriate screw.

Does the insert suit interrupted cuts? Yes, the T515 grade and robust 6.35 mm thickness provide resilience for operations with moderate interruptions; chipbreaker choice should match the specific stability and cutting conditions.

What benefits does the CVD coating provide? The CVD coating on T515 improves abrasive wear resistance at elevated cutting speeds, helping to extend edge life and maintain consistent surface finish during longer runs.

Can the insert be indexed to use multiple cutting edges? The insert features a double‑sided chipbreaker and ISO geometry allowing re‑indexing to fresh cutting edges, which lowers per‑edge tooling costs and supports continuous production.
