TNMA 160420 T5105 — Indexable turning insert for cast iron, Tungaloy

A TNMA 160420 T5105 indexable turning insert designed for ISO‑standard external and internal turning, optimised for stable, high‑speed machining of cast iron under consistent conditions

• CVD‑coated carbide grade T5105
• Optimised for high‑speed cast iron turning
• ISO TNMA triangular 16 mm size
• 2 mm corner radius, 60° wedge angle

Consistent high‑speed performance for cast iron

The insert’s CVD‑coated carbide grade T5105 is formulated to withstand elevated cutting speeds while preserving edge integrity when machining cast iron. In practice this means fewer interruptions for tool changes and more predictable cycle times in series production. The coating helps reduce flank wear and maintains a stable cutting edge, which translates into consistent dimensional results and improved process reliability on finishing and medium‑roughing operations.

Precise geometry and secure clamping for repeatable results

With an ISO‑standard triangular form and a 2 mm corner radius, the geometry supports robust chip formation and allows controlled depth of cut for external and internal turning. The insert is 16 mm across, with a 4.76 mm thickness and a 60° included wedge angle; compatibility with holders is determined by form, clearance angle, tolerance class, clamping and thickness. The cylindrical hole ensures accurate seating and repeatable positioning when mounted in the correct TNMA‑capable holder.

Operational benefits: stability and predictable chip behaviour

Designed without an integrated chipbreaker, this grade performs best in stable setups where machine rigidity and correct toolholding are ensured. Under those conditions the T5105 grade promotes stable chip formation and easier chip evacuation, lowering the risk of built‑up edge and enabling longer intervals between inspections. The result is improved surface finish and a reduced likelihood of unscheduled downtime, supporting leaner production workflows.

System integration and practical workshop considerations

The cutting system comprises the ISO insert, a matching external holder or boring bar, an appropriate shim/clamp set and replacement screws. When selecting holders, attention to the insert’s 0° clearance angle and the tolerance class is essential for correct engagement. For enquiries about suitable holders, application windows or recommended cutting data for specific cast iron grades, Metav Werkzeuge provides application support and technical clarification to help integrate the insert into existing toolsets.
