TNMG110412 T9215 TNMG ISO turning insert for Drehen by Tungaloy

TNMG110412 T9215 is an ISO‑standard indexable insert for turning applications, specified for medium‑steel machining with a CVD coating and a geometry designed for continuous to lightly interrupted cuts.

• CVD-coated carbide grade T9215
• Triangular 60° geometry, 1.2 mm radius
• Double-sided chipbreaker for stable cutting
• With cylindrical hole for secure clamping

Productive medium‑steel turning with optimised wear resistance

This indexable insert is engineered for productive turning of medium‑grade steels. The CVD coating on the carbide substrate provides a high resistance to abrasive wear while the substrate toughness supports fracture resistance during longer runs. As a result, the insert delivers a reliable tool life under steady production conditions and helps to maintain consistent component quality. The combination of coating and substrate is particularly suited to continuous machining and short interruptions, offering a measurable improvement in process stability.

ISO compatibility and how to match the correct holder

The insert belongs to the ISO insert series, so compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness. The triangular TNMG form with a 60° cutting angle and a cylindrical hole requires a matching ISO‑type outside holder or boring bar plus the correct backing/clamp set and replacement screws. Checking these parameters minimises setup time and reduces the risk of incorrect seating. For retrofit or new tool assemblies, the specification ensures predictable fitment and straightforward interchangeability across standard toolholders.

Geometry and chip control for stable, repeatable results

With a 1.2 mm corner radius and a double‑sided chipbreaker, the insert balances strength and chip control to produce consistent surface finishes and dimensional stability. The triangular shape allows indexability to use both cutting edges, improving economy per insert. In practice, the result is fewer insert changes and longer uninterrupted production cycles, which supports higher overall throughput. For applications where moderate interruptions occur, the insert’s toughness reduces the risk of edge chipping and unplanned stoppages.
