CNMG120412 T9235 — ISO turning insert for turning, Tungaloy

A CNMG120412 T9235 indexable turning insert designed for robust performance in steel turning, optimised for interrupted cuts and unstable setups.

• CVD-coated cemented carbide T9235
• Optimised for interrupted cuts and unstable setups
• ISO CNMG120412 insert, rhombic 80° geometry
• 1.2 mm corner radius, 4.76 mm plate thickness

Maximised productivity with a tough CVD-coated grade

The combination of a CVD-coated surface and cemented carbide substrate delivers a durable edge that is particularly effective for steel turning at lower cutting speeds. This T9235 grade is formulated to resist wear while maintaining edge stability in harsher conditions, which translates into fewer indexings and longer tool life. The result is a measurable improvement in process economy through extended tool life and reduced tool-change frequency, supporting higher machine utilisation and predictable cycle times.

Consistent performance under interrupted and unstable conditions

A precisely shaped double-sided chipbreaker promotes stable chip formation even when the cut is discontinuous. The insert’s geometry reduces the risk of edge chipping and minimises vibration sensitivity, so finishing passes remain reliable despite less rigid setups. For operations where interruptions or part run-outs occur, this geometry helps to protect the cutting edge and maintain surface quality, reducing rework and supporting consistent production output.

Clear compatibility and straightforward mounting

Built to the ISO CNMG120412 format, the insert fits standard CNMG holders when the form, relief angle, tolerance class, fastening and thickness are matched. Key dimensions such as 4.76 mm plate thickness, 12 mm inscribed circle and 1.2 mm corner radius ensure predictable engagement with common toolholders. The rhombic plate form with a cylindrical hole supports secure clamping and repeatable positioning, simplifying inventory and holder selection across job changes.

How to choose the right grade and chipbreaker for the operation

Select the chipbreaker and grade according to workpiece material, machining stability and cutting strategy: the T9235 grade is suited for steels where toughness and edge security are prioritised over very high cutting speeds. For fine finishing or high-speed applications, consider a different coating or substrate tuned for those parameters.

FAQ

What materials is this insert best suited for?
The CNMG120412 T9235 insert from Tungaloy is formulated primarily for machining steel, offering toughness and edge security for interrupted cuts.

Can the insert be used on unstable machine setups?
Yes, the geometry and double-sided chipbreaker improve chip control and edge protection, making the insert suitable for less rigid conditions and interrupted cutting.

Which holder types are compatible with this insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening, size and thickness; the insert conforms to the ISO CNMG120412 standard and fits corresponding CNMG holders when these parameters match.

How does the 1.2 mm corner radius affect the machining result?
A 1.2 mm corner radius increases edge strength and reduces the tendency to chip, improving tool life and producing a robust surface finish on roughing passes.

Is this insert single- or double-sided?
The insert is double-sided, providing two usable cutting edges per index and offering economical usage in production environments.
