TNMG 220412 T9235 — Turning insert, CVD-coated carbide, for turning (Tungaloy)

TNMG 220412 T9235 is an ISO-compliant indexable turning insert designed for external and internal turning where stability is limited and cuts are interrupted

• CVD-coated carbide grade T9235
• Optimised for steel and interrupted cuts
• Double-sided chipbreaker, triangle shape
• Compatible with ISO holders, 60° geometry

Consistent edge life under rough conditions

The CVD-coated T9235 grade is formulated for toughness rather than maximum speed, which makes this insert particularly suitable for steel when operating at reduced cutting speeds or where vibration and interrupted cuts occur. The coating enhances wear resistance while the substrate provides fracture toughness, resulting in longer effective tool life and fewer unscheduled insert changes. This combination reduces machine downtime and supports a steadier production flow without sacrificing component integrity.

Geometry and dimensions that simplify clamping and setup

A 60° triangular geometry with a 1.2 mm corner radius and a 4.76 mm plate thickness delivers a reliable balance of strength and cutting accessibility. The insert is double-sided, allowing re-indexing to a fresh edge and extending usage per insert. The 0° relief angle and a cylindrical hole ensure compatibility with standard ISO holders; compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness. These features permit straightforward toolholder selection and repeatable set-ups, which in turn improve process stability and reduce set-up time.

Practical guidance for productive turning operations

Intended for turning applications, the insert serves both external and internal operations when paired with a suitable outer holder or boring bar, a correct shim/clamp set and replacement screws. The double-sided chipbreaker supports controlled chip formation in unstable conditions, provided the cutting data is adapted to the grade’s recommendation for lower cutting speeds. Selecting the appropriate chipbreaker and grade according to workpiece material and machine rigidity results in improved surface finish and more predictable tool life, supporting efficient batch production and shorter regrinding or replacement cycles.

FAQ

What materials is this insert suitable for?
The Tungaloy TNMG 220412 T9235 insert is optimised for machining steel; the T9235 grade gives improved toughness for interrupted cuts and unstable conditions.

Is the grade T9235 suitable for high cutting speeds?
No, the T9235 grade is designed for lower cutting speeds where toughness and resistance to chipping are prioritised over maximum speed.

How many edges are available per insert and how is it indexed?
The insert is double-sided and triangular, providing multiple indexable cutting edges; turning the insert to a fresh edge restores cutting performance.

Which holder details must be checked for compatibility?
Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness; matching the ISO specifications ensures proper clamping and repeatable set-up.

What is the manufacturer SKU and article number for ordering?
Manufacturer SKU: TUN6785897; Article number: 6785897; these identifiers refer to the TNMG220412 T9235 turning insert from Tungaloy.
