TNMA 160412 T5105 — ISO turning insert (triangle, 60°) by Tungaloy

The TNMA160412 T5105 is an ISO triangular turning insert designed for high-speed external and internal turning applications, optimised for cast iron machining.

• CVD-coated carbide grade T5105
• Triangular ISO insert, 60° cutting angle
• Corner radius 1.2 mm for robust edges
• Suitable for high-speed cast iron turning

Maximise throughput with a wear-resistant cutting grade

The combination of CVD-coated carbide and the T5105 grade targets continuous high-speed machining, offering a balance between wear resistance and edge stability. The coating reduces abrasive wear during long cuts on cast iron, while the substrate maintains toughness under steady cutting conditions. This results in fewer tool changes and more predictable tool life, which supports higher machine uptime and better throughput in serial production. The insert’s design aims to maintain form accuracy and surface finish even when machining at elevated cutting speeds.

Seamless integration into ISO tooling systems

As an ISO-standard triangular insert, the part integrates with common external holders and boring bars when the holder’s form, clearance angle and tolerance class match the insert dimensions. The 0° clearance angle and the cylindrical hole require matching clamping systems and torque settings to ensure repeatable seating. The insert’s triangular geometry with a 60° cutting angle provides three indexed edges, increasing economy per insert and simplifying inventory management. System components typically include a suitable outer holder or boring bar, a shim/clamp set and replacement screws.

Process stability and edge strength for consistent results

A 1.2 mm corner radius delivers a robust cutting edge that tolerates interruptions and slight variations in feed without premature chipping, which is beneficial for medium to heavy finishing passes. The absence of a dedicated chipbreaker in this specification means the focus is on uninterrupted chip flow under stable conditions; pairing the insert with appropriate feeds and coolant strategies reduces built-up edge and improves workpiece quality. For shops seeking repeatability and low-variation surface finishes, this insert supports consistent cycle times and predictable regrinding or replacement intervals.

FAQ

What materials is this insert designed for?
The insert is specified for high-speed machining of cast iron, using the CVD-coated T5105 grade to resist abrasive wear under stable cutting conditions.

How many cutting edges are available per insert?
The triangular plate form provides three indexed edges; the TNMA160412 geometry allows rotation to fresh edges to extend tool life.

Is a chipbreaker included with this insert?
This specification lists no chipbreaker; the insert is intended for applications where uninterrupted chip flow and stable machining are present.

What holder characteristics are required for correct seating?
Correct compatibility depends on matching holder form, clearance angle, tolerance class, fastening method, size and thickness; ensure the clamping system suits a 0° clearance-angle, triangular ISO insert.

Can the insert be used for internal turning?
Yes, the insert is suitable for both external and internal turning operations, provided that the toolholder and setup maintain required rigidity and clearance.
