RNMG 120400 T9235 61 Wendeplatten - Tungaloy

The combination of a CVD-coated carbide T9235 grade with the RNMG geometry and chipbreaker 61 ensures reliable performance in interrupted cuts and unstable conditions; order the inserts via Metav Werkzeuge or consult their technical advisors for application-specific recommendations.

RNMG 120400 T9235 RNMG120400-61 — Tungaloy turning insert with CVD-coated carbide and chipbreaker 61

The RNMG120400-61 insert is an ISO-standardised turning grade designed for steel machining under interrupted or unstable cutting conditions.

• CVD-coated grade T9235 for steel
• ISO RNMG geometry (round, 12 mm)
• 0° clearance angle for specific cutting profiles
• Cylindrical hole for secure clamping

Greater reliability when machining interrupted cuts

The CVD coating combined with the T9235 carbide grade is formulated to resist chipping and premature wear when machining steel at moderate cutting speeds. In practice, this means improved edge stability in interrupted cuts and when workpiece support is less than ideal. The chipbreaker 61, matched to the RNMG shape, helps control chip formation and evacuation, which reduces the risk of rework and supports a steadier production rhythm.

Fast, repeatable insert changes and secure clamping

The insert’s round, 12 mm format with a cylindrical hole and defined tolerance class enables reliable seating in ISO-compatible holders. Because compatibility is determined by form, clearance angle, tolerance class, fixing style, size and thickness, the insert integrates easily into established tool systems when the correct clamping components are used. The system approach — insert, holder, shim and clamping set — lowers changeover time and increases positional repeatability, contributing to shorter downtimes and more predictable machining cycles.

Predictable results and selection guidance for turning operations

ISO standardisation ensures interchangeability across comparable tool systems and simplifies logistics for batch production. The 0° clearance angle and the T9235’s toughness make this grade particularly suited to steel when lower cutting speeds are chosen or when intermittent cutting is unavoidable. For best results, match the chipbreaker and grade to the material, workpiece support and machine stability; this balanced selection maximises tool life and surface quality while keeping operating costs under control. For complex tasks, consult technical specifications or Metav Werkzeuge’s advisors to select the optimal chipformer and process parameters.

FAQ

Which materials is this insert best suited for?
The RNMG120400-61 in T9235 grade is optimised for machining steel, particularly where interrupted cuts or unstable conditions require a tougher grade and reliable edge behaviour.

How is the insert secured in the holder?
The insert uses a cylindrical hole and is intended for ISO-compatible holders; correct clamping components (shim, clamping set and screws) ensure secure and repeatable seating.

What is the purpose of chipbreaker 61?
Chipbreaker 61 is engineered to manage chip formation for the RNMG geometry, improving evacuation and reducing the chance of built-up edge during steel turning.

Is this insert coated and how does the coating help?
Yes — the insert features a CVD coating that enhances wear resistance and helps maintain edge integrity in interrupted cutting and at moderate cutting speeds.
