CNMG 190612 T9235 indexable turning insert — Tungaloy, CVD-coated carbide, 80° rhombic

CNMG190612 T9235 Tungaloy insert designed for general turning applications, optimised for steel machining under interrupted or less stable cutting conditions

• ISO-compliant rhombic shape 80°
• CVD-coated carbide grade T9235
• 1.2 mm corner radius for robust cuts
• Double-sided insert with cylindrical hole

Consistent cutting under interrupted and unstable conditions

The CVD-coated carbide grade T9235 is formulated as a tough grade for machining steel at moderate to lower cutting speeds and where interruptions or vibration are expected. This combination of substrate and coating provides enhanced edge strength and wear resistance while retaining fracture toughness; the result is a more predictable tool life in demanding turning operations. With the appropriate chipbreaker chosen for the workpiece and process stability, material removal can be maintained without frequent insert changes, improving productivity and reducing unplanned stoppages.

Secure geometry and straightforward holder compatibility

The insert follows ISO indexing standards and its compatibility with a holder is determined by form, clearance angle, tolerance class, fastening, size and thickness. The 80° rhombic outline, 6.35 mm plate thickness and the presence of a cylindrical hole support secure clamping and repeatable seating in standard external holders or boring bars. Dimensional consistency is critical for repeatable results; therefore the insert is supplied to the specified ISO geometry so that clamping forces are applied uniformly and cutting edge position remains stable during operation.

Economical handling and application flexibility

As a double-sided indexable insert, this grade offers twice the number of usable cutting edges before disposal, which lowers tooling costs per part in many turning tasks. The 1.2 mm corner radius increases the edge strength and is suited to more robust cuts or light roughing passes where edge chipping is a concern. Selection of the correct chipbreaker and matching the insert grade to the application — for example prioritising toughness for interrupted cuts — leads to fewer tool changes and better overall process economy.

Practical assembly and process recommendations for stable production

The tool system is composed of the ISO insert together with a matching external holder or boring bar, an appropriate underlay / clamp set and replacement fixing screws. For best results, the insert grade T9235 should be paired with a chipbreaker and cutting parameters that reflect the workpiece material and machine rigidity; if the setup is unstable, reducing cutting speed and increasing feed within the insert’s permitted range can prevent premature wear. The insert designation is CNMG190612 and it is intended for turning; compatibility checks with the chosen holder are recommended to ensure correct seating and repeatable performance.

FAQ

What materials is this insert designed for? This insert is optimised for machining steel; the CVD-coated T9235 grade provides toughness suited to lower cutting speeds and interrupted cuts encountered when turning steel components.

How is the insert secured in the holder? The indexable insert is clamped via its cylindrical hole and seating geometry; compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness, so matching the insert to a compatible holder is essential.

Is the insert reversible and how many cutting edges are available? The insert is double-sided, providing two usable cutting edges per face where applicable; proper indexing doubles the usable life compared with single-sided alternatives.

What benefits does the 1.2 mm corner radius bring? A 1.2 mm corner radius increases edge robustness, reducing the risk of chipping in interrupted or unstable cuts and enabling more consistent surface finishes under heavier engagement.

How should the chipbreaker and grade be selected for a specific operation? Select the chipbreaker and T9235 grade according to workpiece material, desired surface finish and machine stability; for unstable setups, prefer tougher grades and chipbreakers designed for interrupted cutting.
