DNMG 150404 T9215 — ISO turning insert (rhombic 55°) by Tungaloy

The DNMG150404 T9215 Tungaloy insert is an ISO‑standard rhombic turning insert engineered for external and internal turning in medium‑duty applications

• CVD-coated carbide grade T9215
• Optimised for medium Stahl machining
• Rhombic 55° geometry, 0° clearance
• Double-sided with cylindrical hole

Longer tool life through a wear-resistant coating

The CVD‑coated T9215 carbide combines high wear resistance with dependable fracture toughness, which results in extended tool life during continuous to slightly interrupted turning. The chemical vapour deposition layer provides a hard, wear‑resistant surface that reduces flank wear at elevated cutting speeds; this leads to fewer indexings, more stable process windows and a measurable improvement in productivity. For production environments seeking consistent throughput, the coated substrate sustains more aggressive cutting parameters without sacrificing component quality.

Stable geometry for consistent surface finish and accuracy

A rhombic 55° geometry and a 0.4 mm corner radius deliver repeatable cutting engagement and reliable part profile control, while the 0° clearance supports effective chip formation on typical turning cycles. The insert’s double‑sided design and the cylindrical hole enable secure mounting and cost‑efficient use of both cutting edges. The 4.76 mm plate thickness contributes to rigidity under load, helping to reduce vibration and produce a better surface finish with predictable dimensional results on turned features.

Designed for productive Stahl turning with balanced toughness

This grade was developed as a first choice for medium Stahl machining, combining high wear resistance with the mechanical strength to resist chipping under varying cutting conditions. The material pairing of coated carbide and the Tungaloy substrate encourages higher metal removal rates and stable tool life in series production. For shops transitioning from general‑purpose grades, the T9215 grade offers a balance between long life and secure edge integrity, allowing process engineers to increase cutting speeds or extend tool change intervals while maintaining part quality.

Clear guidance on selection and system compatibility

Compatibility with toolholders depends on form, relief angle, tolerance class, fastening method, size and thickness; the ISO system includes the insert, a matching external holder or boring bar, a support shim/clamping set and replacement screws. Select a chipbreaker that matches the workpiece material and the machining mode, and prefer a grade suited to continuous or slightly interrupted cuts for optimum results. Assistance with holder matching and process parameters is available from Metav Werkzeuge’s technical advisors, ensuring an efficient integration into existing turning centres.

FAQ

Which materials is this insert best suited for?
The DNMG150404 T9215 Tungaloy insert (SKU 6950961‑Tungaloy) is optimised for medium Stahl machining, offering a balance of wear resistance and toughness for common steels.

Can the insert be used for interrupted cuts?
Yes, the T9215 grade is suitable for continuous to slightly interrupted cuts; its fracture resistance helps maintain edge integrity under light interruptions.

How many cutting edges are available per insert?
The DNMG150404 is double‑sided, providing multiple indexable cutting edges and improving cost efficiency per edge on production runs.

What does the 0.4 mm corner radius affect in machining?
A 0.4 mm corner radius improves strength at the insert tip and helps achieve robust edge strength for roughing and medium finishing passes without excessive stress concentration.

Which holder features are required for secure clamping?
Secure compatibility is achieved when the holder matches the insert form, relief angle, tolerance class, fastening method, size and thickness; Metav Werkzeuge can advise on the correct holder selection.
