CNMG 120412 T9225 CNMG120412 – Tungaloy turning insert, CVD-coated carbide, 80° rhombic

A CNMG120412 T9225 turning insert designed for external and internal turning in medium to heavy steel machining, offering robust universal performance and secure clamping via a cylindrical hole.

• CVD-coated carbide for extended life
• 80° rhombic geometry for stable cuts
• 1.2 mm corner radius for versatility
• Cylindrical hole for reliable mounting

Optimised cutting performance for variable turning conditions

The CVD-coated carbide grade T9225 is formulated as a robust universal grade for medium to heavy steel machining. This composition prioritises a balance of toughness and wear resistance, which is particularly useful where cutting conditions vary or where slightly interrupted cuts occur. The integrated double-sided chipbreaker promotes controlled chip formation, lowering the risk of built-up edge and improving process stability. For operators unfamiliar with coatings: CVD (chemical vapour deposition) adds a thin, hard layer that reduces abrasive wear and extends tool life under industrial cycle conditions.

Reliable geometry and secure clamping reduce downtime

The insert’s ISO rhombic geometry and 80° cutting angle give a predictable contact pattern with the workpiece, supporting consistent surface finish and tool engagement. The 1.2 mm corner radius widens the application window between finishing and semi-finishing tasks, while the cylindrical hole ensures secure seat and repeatable positioning in compatible holders. Compatibility with a toolholder depends on form, relief angle, tolerance class, fixation method, size and thickness; the insert’s dimensions (size 12, thickness 4.76 mm) conform to ISO standards for straightforward holder selection. The product designation CNMG120412 identifies the shape and nominal dimensions for machine setup and tool databases.

Economic advantages through fewer tool changes and predictable results

Selecting a universal grade such as T9225 can lower tooling complexity in mixed-production environments: one grade copes with a wide range of steel alloys and fluctuating cutting conditions, reducing inventory and set-up time. The controlled chipbreaking and CVD coating together contribute to longer effective cutting time, which supports higher component throughput and less frequent intervention. When paired with an appropriate holder and clamping kit, the insert promotes reproducible part quality and reduced cycle variability — a rational path to improved process economics in turning operations.

FAQ

What materials is this insert intended for?
The Tungaloy CNMG120412 T9225 insert is intended primarily for medium to heavy steel machining and is designed to handle changing engagement conditions.

How does the T9225 grade affect tool life?
The T9225 CVD-coated carbide offers enhanced wear resistance and toughness, extending effective cutting time under mixed and interrupted turning operations.

Is the insert reversible or single-sided?
The CNMG120412 insert is double-sided, providing two usable cutting edges per side and contributing to economical usage.

Which holder features are required for correct compatibility?
Correct compatibility depends on holder form, relief angle, tolerance class, fixation and matching size/thickness; the insert’s cylindrical hole and ISO rhombic shape require a matching clamping seat and screw arrangement.

Can this insert be used for finishing passes?
With its 1.2 mm corner radius and 80° geometry, the insert can be used for semi-finishing and certain finishing tasks, subject to cutting parameters and machine stability.
