CNMG120412 T9235 — Turning insert (ISO 120412), CVD-coated carbide, 1.2 mm radius — Tungaloy

CNMG120412 T9235 is an ISO‑standard rhombic turning insert engineered for external and internal turning of steel; the CVD‑coated carbide grade is optimised for interrupted cuts and unstable machining conditions

• CVD-coated carbide grade T9235 for steel machining
• ISO‑standard CNMG120412 geometry, rhombic form
• 1.2 mm corner radius for robust edge strength
• Double-sided chipbreaker with cylindrical hole

Consistent cutting performance under unstable conditions

The CVD‑coated T9235 carbide formulation delivers a balance of toughness and wear resistance that is particularly effective for machining steel at moderate cutting speeds or where interrupted cuts occur. The combination of the coated substrate and the rhombic geometry helps maintain a stable cutting edge, reducing the frequency of edge failures and unplanned tool changes. This stability translates directly into improved process predictability, longer tool life and reduced overall production costs in batch and mixed‑batch turning operations.

Straightforward integration with ISO holders and secure clamping

Built to ISO dimensions, the insert’s compatibility with holders depends on geometry, relief angle, tolerance class, fixation and thickness. The rhombic shape with a 0° relief angle, 4.76 mm plate thickness and a cylindrical hole ensure secure locating and fastening in standard CNMG‑capable external holders or boring bars. The double‑sided design allows two indexed cutting edges per face, offering efficient use of the insert and straightforward reindexing. For workshops adopting ISO‑based tool systems, this geometry simplifies tool inventory and reduces downtime when swapping or reseating inserts.

Productivity benefits and recommended applications

This insert is designed for turning applications where robustness is required: external and internal turning of steel components, interrupted cuts and less‑stable setups. The double‑sided chipbreaker aids chip control across varying depths of cut, while the 1.2 mm corner radius supports stronger edge integrity and improved surface finish in roughing passes. Selecting the correct chipbreaker and grade for the workpiece material and machine stability is advised to maximise cutting performance and tool life; the specification here directs users to a grade optimised for durable, reliable machining rather than only maximum speed.

FAQ

What materials is this insert designed for?
The insert is intended primarily for machining steel; the T9235 CVD‑coated carbide grade is formulated for tougher steel applications and interrupted cuts.

How does the double-sided chipbreaker affect performance?
A double‑sided chipbreaker provides two usable cutting edges per face and improves chip control across a range of depths of cut, enhancing productivity and reducing manual chip handling.

Which holder features must match the insert for correct fitment?
Compatibility requires matching the insert form, relief angle, tolerance class, fixation method, size and thickness; the ISO‑standard geometry simplifies selection for ISO‑capable holders.

Is the clearance angle fixed for this geometry?
This insert is specified with a 0° relief; holders and setups must account for this when defining cutting parameters and tool alignment.

How many edges are available before reindexing or replacement?
The double‑sided construction provides multiple usable edges through indexing; actual edge count depends on usage and wear, but the design aims to maximise usable cutting life.
