CNMG120408 T9235 turning insert for turning by Tungaloy

CNMG120408 T9235 is an ISO rhombic turning insert designed for external and internal turning of steel, optimised for interrupted cuts and unstable machining conditions

• CVD-coated T9235 for steel performance
• Rhombic CNMG geometry with 80° angle
• Double-sided chipbreaker for reliable chips
• Cylindrical-hole design for secure clamping

Consistent chip control for productive turning

The combination of a CVD-coated T9235 carbide grade with a double-sided chipbreaker provides controlled chip formation even when conditions fluctuate. This optimised pairing reduces the risk of built-up edge and contributes to a more consistent surface finish on steel, particularly at lower cutting speeds or where cuts are interrupted. The chipbreaker design focuses on reproducible chip separation, which helps to maintain cycle times and reduce secondary finishing work, delivering measurable productivity improvements on turning operations.

Robust geometry that enhances edge stability

The rhombic CNMG geometry, with an 80° approach and a 0.8 mm corner radius, offers a balance between edge strength and versatility. Combined with a plate thickness of 4.76 mm, the insert provides rigidity that supports stable cutting behaviour under moderate forces. Made from high-quality carbide, the grade and geometry are selected to resist chipping during interrupted feeds and to extend the usable life of the cutting edge, which translates into fewer tool changes and improved machine uptime.

Straightforward integration with existing toolholders

This insert conforms to ISO-standard dimensions for CNMG-type plates; compatibility with a holder is determined by form, relief angle, tolerance class, clamping method, size and thickness. The cylindrical hole and standard mounting features ensure a secure, repeatable fit in compatible external holders or boring bars. The specified 0° relief angle and the plate’s overall geometry make it suitable for a wide range of standard turning fixtures, simplifying inventory and holder selection for workshops that run mixed turning operations.

Practical guidance for application and longevity

The T9235 grade is formulated to perform well in steel turning at conservative cutting speeds and where stability is compromised. For best results, select the chipbreaker and grade that match the workpiece material and machining dynamics. Monitor the cutting edge for signs of wear or chipping and replace the insert before deterioration affects component tolerances or surface quality. Regularly check clamping torque on the holder and ensure the mating surfaces are clean to maintain the secure seating that the cylindrical-hole design provides; these simple measures protect tool investment and support consistent part quality.

FAQ

What materials is this insert intended for?
The CNMG120408 T9235 insert from Tungaloy (SKU 6785802-Tungaloy) is optimised for machining steel, with the CVD-coated T9235 grade offering improved resistance in interrupted cuts and unstable conditions.

How is holder compatibility ensured?
Compatibility depends on the insert form, relief angle, tolerance class, clamping method, size and thickness; the CNMG120408 designation follows ISO standards, and the cylindrical hole aids safe clamping in compatible holders.

What advantages does the T9235 grade provide?
Tungaloy’s T9235 grade is a CVD-coated carbide designed for tougher conditions at lower cutting speeds, offering stable chip formation and longer edge life under interrupted or unstable cutting.

Is the insert reversible or single-use per edge?
The plate features a double-sided chipbreaker, allowing use of the alternate cutting edges when one side reaches wear limits; actual edge count and rotation depend on the chosen geometry and machining strategy.

Which features help when machining interrupted cuts?
The combination of a rhombic CNMG geometry, a robust 0.8 mm corner radius and the T9235 coating supports resistance to chipping and promotes consistent chip control during interrupted turning sequences.
