TNMG160412 T9235 TNMG turning insert for Drehen – Tungaloy

TNMG160412 T9235 is an ISO-format triangular turning insert designed for external and internal turning operations in demanding steel applications.

• CVD-coated carbide grade T9235 for steel
• ISO TNMG160412 triangular insert, 60° geometry
• 1.2 mm corner radius for robust edge strength
• Double-sided insert with cylindrical hole for stability

Consistent cutting performance for unstable conditions

The insert delivers consistent cutting performance in applications where vibration or interrupted cuts occur. The CVD-coated surface improves edge resistance while the carbide substrate provides toughness under shock loads. As a result, quieter toolpaths and reduced edge chipping can be expected when the correct feed and speed parameters are selected. By selecting the appropriate chipbreaker and grade for the workpiece, production uptime is supported and tool-change frequency is lowered, which contributes to more predictable cycle times and lower overall machining cost.

System compatibility and secure clamping for predictable results

Compatibility is governed by insert form, relief angle, tolerance class, clamping method, size and thickness. The ISO TNMG format with 60° geometry and a cylindrical hole facilitates secure fastening in standard clamping systems, ensuring repeatable positioning and axial stability. The triangular shape and double-sided design provide multiple usable edges, improving tool economy. When paired with a suitable ISO external holder or boring bar, the insert supports robust set-ups even in less rigid conditions, translating to improved dimensional consistency on turned components.

Optimised grade and chip control for steel turning

The T9235 grade is a tough, CVD-coated carbide developed for steels at reduced cutting speeds and for applications with intermittent engagement. Its composition prioritises edge strength and wear resistance rather than maximum cutting speed, making it suitable for mixed batch work and components with variable clamping. The doppelseitig chipbreaker style (double-sided) assists in chip control across a range of feeds, reducing re-cutting of chips and helping to maintain surface finish without aggressive cutting parameters.

Practical advantages at the machine and shopfloor level

A 1.2 mm corner radius offers a balance between edge strength and achievable surface finish, while the 4.76 mm thickness and 16 mm size support stable contact with the holder under typical turning loads. The insert’s design simplifies inventory management: a single ISO TNMG insert can be used across multiple holders that accept the format, reducing tooling variants. For complex or high-value components, Metav Werkzeuge can provide application guidance and recommend matching holders, screws and backing pads to optimise life and process reliability.

FAQ

What materials is this insert suitable for?
The TNMG160412 T9235 insert is optimised for machining steel; the tough T9235 grade and CVD-coated carbide substrate give improved resistance in interrupted cuts and less rigid set-ups.

How is compatibility with holders determined?
Compatibility depends on insert form, relief angle, tolerance class, clamping method, size and thickness; the ISO TNMG format and cylindrical hole facilitate use with standard external holders and boring bars.

What is the corner radius and why does it matter?
This insert has a 1.2 mm corner radius, which enhances edge strength and reduces the risk of chipping while still allowing a good surface finish in typical turning operations.

Is the insert coated and how does that help?
Yes, the insert uses a CVD coating on a carbide substrate; the coating improves wear resistance and edge life, especially under lower cutting speeds and interrupted machining.

How many cutting edges are usable on this insert?
As a triangular, double-sided insert, the TNMG160412 provides multiple usable edges, enabling efficient rotation and reuse to extend overall tool life.
