TNMG160408 T505 TNMG – Indexable turning insert for Turning (Tungaloy)

The TNMG160408 T505 is an ISO-standard triangular indexable turning insert designed for efficient external and internal turning of cast iron, featuring a CVD-coated carbide grade optimised for economical, high-stability machining.

• CVD-coated carbide grade T505 for cast iron
• Triangular ISO insert, size 16 mm, 0.8 mm radius
• Double-sided chipbreaker for stable chip control
• Cylindrical hole, 4.76 mm plate thickness

Faster, more economical cast-iron turning through optimised grade and geometry

The combination of a CVD-coated carbide matrix and the T505 grade delivers a cost-effective balance between tool life and cutting speed for grey and nodular cast iron applications. The insert’s double-sided chipbreaker is engineered to support consistent chip formation and evacuation, reducing interruptions and enabling longer continuous cuts. With a 0.8 mm corner radius, the component provides improved edge strength compared with very small radii while still permitting fine profile work. These technical choices translate into measurable productivity gains on the shop floor: fewer tool changes, reduced downtime and more consistent cycle times.

Consistent clamping, reproducible results and simple holder compatibility

As an ISO 160408 designation, the triangular insert follows standard dimensions and tolerances that simplify selection of a matching turning holder. The triangular form and the presence of a cylindrical hole allow secure mounting and repeatable positioning; the plate thickness of 4.76 mm and the specified relief angle of 0° are key parameters when checking holder compatibility. Where holders vary by form, clearance angle or tolerance class, the insert’s standardised geometry makes verification straightforward and supports predictable repeatability in serial production. The precise specification aids process engineers in calculating cutting parameters and establishing stable feeds and speeds.

System thinking: how the insert fits your workflow and what to consider

This insert is intended to be used as part of a complete system: the indexable insert, a compatible external holder or boring bar, an appropriate clamp or shim and the correct screw. For reliable performance, choose the chipbreaker style and the T505 grade according to workpiece stability, interrupted cuts and required cutting speed. The insert is especially suited to cast-iron turning where a balance of wear resistance and economical tool life is required. For complex or high-volume applications, technical consultation can help tailor holder selection, cutting data and tool-change intervals to the production environment. If additional technical information is required, Metav Werkzeuge provides support by email and phone to verify fit and suitability.

FAQ

What materials is this insert suitable for?
The TNMG160408 T505 insert is specified for machining cast iron, with the CVD-coated T505 grade optimised for economic performance on these materials.

How is the insert mounted in a holder?
Mounting uses the insert’s cylindrical hole together with the matching clamp or shim in a compatible ISO turning holder; the ISO 160408 designation helps ensure correct fit.

What advantages does the T505 grade provide?
The T505 CVD-coated carbide grade is chosen for a balance of wear resistance and economy, supporting efficient machining of cast iron while maintaining acceptable tool life.

How does the chipbreaker affect production?
The double-sided chipbreaker promotes controlled chip formation and evacuation, which stabilises cutting conditions and reduces the risk of downtime caused by poor chip control.

How many indexable corners are available with a triangular insert?
The triangular design provides multiple indexable corners; the ISO-standard form of the TNMG160408 allows straightforward indexing to restore a fresh cutting edge.
