CNMG190612 T9205 — ISO turning indexable insert for turning by Tungaloy

CNMG190612 T9205 indexable insert engineered for productive steel turning in ISO systems, offering a CVD coating for wear resistance and a rhombic 80° geometry for versatile external and internal operations

• ISO rhombic CNMG insert, 80° geometry
• CVD-coated carbide grade T9205
• Double-sided chipbreaker, cylindrical hole
• Thickness 6.35 mm, corner radius 1.2 mm

Higher productivity through a wear‑resistant grade

The insert employs a CVD-coated cemented carbide grade T9205 developed for productive turning of Stahl. This coating enhances wear resistance at elevated cutting speeds, which translates into longer tool life and fewer interruptions for insert changes. For process planners and machinists, the tangible result is reduced cycle times and a more predictable replacement interval, supporting continuous production runs under stable clamping and machine conditions.

Precise geometry for secure clamping and consistent cuts

The CNMG190612 follows ISO dimensions with a rhombic outline and an 80° included angle, combined with a cylindrical hole and a 0° relief angle to match standard holders. The plate thickness of 6.35 mm and corner radius 1.2 mm deliver mechanical stability in the cut and consistent edge strength. Because compatibility is defined by form, relief angle, tolerance class, fastening, size and thickness, this insert fits reliably into ISO toolholder systems, enabling straightforward indexing and repeatable positioning for both external and internal turning.

Controlled chip formation for improved surface quality

Equipped with a double-sided chipbreaker, the design actively shapes chips to prevent long, stringy swarf and to assist evacuation in confined toolrooms. Effective chip control reduces the risk of re-cutting and promotes a superior surface finish, particularly when machining Stahl under steady feed and depth‑of‑cut regimes. Selecting the matching chipbreaker and grade to suit workpiece material and setup stability ensures the process delivers the intended productivity and part quality.

System advice and recommended use

This indexable insert is intended for use in an ISO‑based system comprising an appropriate holder or boring bar, a backing pad/clamp set and replacement screws. It is optimised for external and internal turning of Stahl where the setup is rigid and cutting speeds are comparatively high; the combination of grade and geometry performs best under those stable conditions. For integration into existing tooling arrays, verify holder form, free angle and clamp compatibility to benefit from the insert’s full performance potential.
