TNMG 160412 T9235 Wendeplatten - Tungaloy

Take advantage of the combination of CVD-coated carbide T9235, a 60° triangular geometry and a robust 1.2 mm corner radius to maintain productive turning under interrupted or unstable cutting conditions; order the insert via Metav Werkzeuge or consult our experts for application guidance.

TNMG 160412 T9235 — turning indexable insert, CVD-coated carbide (Tungaloy)

TNMG160412 T9235 is an ISO triangular indexable insert for turning, engineered for steel applications and optimised for interrupted and unstable cuts.

• CVD-coated carbide grade T9235
• Triangular ISO insert, 60° geometry
• 1.2 mm corner radius for robust cuts
• Double-sided insert with cylindrical hole

Predictable performance in demanding steel turning

The CVD-coated carbide composition (grade T9235) delivers a balance of toughness and wear resistance that is particularly suited to steel machining at moderate cutting speeds. The coating improves thermal stability and reduces flank wear, which helps to extend tool life under fluctuating conditions. As a result, shops can maintain consistent cycle times and reduce unscheduled tool changes, supporting a more efficient production flow without sacrificing component quality.

Geometry and system compatibility that simplify processes

A 60° triangular geometry with a 1.2 mm radius provides robust edge strength and adaptability for both external and internal turning. Compatibility with ISO holders is determined by form, clearance angle, tolerance class, fastening, size and thickness; the insert sits in a system that typically includes a matching external holder or boring bar, a shim/clamp set and spare screws. Clear geometry and standardised interfaces reduce setup complexity and enable quick indexing, which supports higher machine utilisation and predictable changeover times.

Resilience for interrupted cuts and unstable conditions

The insert's combination of a tough carbide substrate and a protective CVD coating is designed to withstand mechanical shock and variable chip formation. The double-sided chipbreaker improves chip control across a range of cutting parameters, lowering the incidence of built-up edge and enhancing surface finish consistency. This construction is particularly beneficial when processing parts with interruptions, shoulders or variable rigidity, where tool fracture risk is elevated.

Practical selection guidance for workshop use

When selecting an insert grade and chipbreaker, match the T9235 toughness to lower cutting speeds and applications with instability or interrupted cutting; select a firmer grade if the process allows higher speeds. The triangular, indexable insert design offers two usable cutting edges per side and easy re-indexing; ensure holder compatibility by checking form, thickness (4.76 mm) and fastening method. Where surface finish or dimensional tolerance is critical, combine the insert with a stabilised clamping system and suitable machining parameters to exploit the insert’s wear characteristics.

FAQ

What materials is this insert best suited for?
The TNMG160412 T9235 insert is formulated for machining steel; the CVD-coated T9235 grade provides toughness for interrupted cuts and less stable machining conditions.

How does the T9235 coating affect performance?
The CVD coating on the insert helps to reduce flank wear and improves thermal stability, which increases reliable cutting life in steel turning applications.

Is the insert reversible and how many cutting edges are available?
The triangular TNMG insert is double-sided and indexable, offering multiple usable edges per insert to reduce tooling costs and downtime.

Which parts are needed to assemble a complete turning system?
A complete system includes the ISO insert, a compatible external holder or boring bar, a shim/clamp set and replacement screws; correct matching is determined by form, clearance angle, tolerance class, fastening, size and thickness.
