TNMG160412 T9235 — Indexable turning insert for turning (Tungaloy)

A TNMG160412 T9235 indexable insert designed for external and internal turning on steel, offering a CVD-coated carbide grade for interrupted and unstable cutting conditions.

• CVD-coated carbide grade T9235
• Suitable for steel and unstable cuts
• Triangle insert with 60° cutting geometry
• Double-sided design with cylindrical hole

Improved process reliability and longer tool life for interrupted turning

The insert provides a tough CVD-coated carbide formulation that reduces flank and crater wear in low cutting-speed, unstable conditions. With a 1.2 mm corner radius, the geometry strengthens the cutting edge, which translates into fewer unexpected indexings and extended tool life — a direct advantage for workshops handling interrupted cuts or variable stock. The combination of a robust grade and dedicated chipbreaker ensures consistent machining performance and reduced tooling costs per component.

Fast integration into ISO tool systems for operational efficiency

Designed as part of the ISO turning insert family, the component is compatible with matching external holders or boring bars according to form, relief angle, tolerance class, clamping and size. The triangular 60° design and double-sided construction provide multiple usable edges, lowering per-edge cost and simplifying inventory. The insert thickness of 4.76 mm and the cylindrical hole facilitate secure clamping, enabling repeatable seating and stable cutting — key factors for predictable cycle times and easier process planning.

Better surface quality and economical performance in steel machining

The double-sided chipbreaker geometry promotes controlled chip formation and evacuation, improving surface finish on external and internal turning operations while limiting built-up edge in difficult cuts. The T9235 grade is formulated for steel and excels in conditions with intermittent engagement, offering a balance of toughness and wear resistance. Fewer tool changes and reliable edge behaviour translate into measurable productivity gains and a more economical machining process over multiple workpieces.

FAQ

What materials is this insert intended for? The Tungaloy TNMG160412 T9235 insert is intended primarily for machining steel, where its tough CVD-coated carbide grade performs well under interrupted or unstable cutting conditions.

How many cutting edges are available per insert? With a triangular, double-sided design, the insert provides six usable cutting edges (three corners × two sides), which improves cost efficiency per edge.

What does the T9235 grade indicate? T9235 denotes a CVD-coated carbide grade optimised for toughness and wear resistance in steel turning, reducing edge chipping during interrupted cuts.

How is the insert secured in the holder? Compatibility and secure clamping are ensured by matching the insert form, relief angle, tolerance class, clamping method, size and thickness; the insert is used with a suitable external holder or boring bar and a clamp/screw system.

When is a 1.2 mm corner radius recommended? A 1.2 mm corner radius strengthens the cutting edge and is recommended for roughing and interrupted cuts where edge stability and resistance to chipping are priorities.
