CNMG 120408 T9235 Turning Insert — CVD-coated carbide, 0° clearance (Tungaloy)

The CNMG120408 T9235 is an ISO-standard turning insert designed for robust external and internal turning applications, optimised for machining steel where interrupted cuts or unstable setups demand a tough grade and reliable chip control.

• CVD-coated carbide grade T9235
• Optimised for steel turning
• Double-sided chipbreaker for interrupted cuts
• Rhombic 80° shape, 0° clearance

Consistent performance for challenging steel turning

The combination of a CVD coating and a tough carbide substrate in this turning grade provides a balanced resistance to wear and chipping. Specifically designed for steel at reduced cutting speeds and for operations with poor stability, the insert supports longer machining intervals and reduces unplanned tool changes. The robust edge behaviour produced by the coating and substrate pairing helps to maintain a predictable surface finish and cycle time, contributing directly to improved shop-floor productivity and cost efficiency.

Secure compatibility and correct clamping for predictable results

This insert follows ISO dimensions, so compatibility with holders is determined by form, relief angle, tolerance class, mounting method, size and thickness. The rhombic profile with an 80° included angle and a cylindrical hole requires a matching ISO external holder or boring bar, plus the correct support pad and clamping set. Verifying these parameters before assembly ensures repeatable clamping stiffness and avoids premature edge damage, making setup both safer and quicker for production runs.

Durability under interrupted cuts and unstable conditions

The T9235 designation denotes a tough, CVD-coated carbide optimised for interrupted cuts and less favourable setups. With a double-sided chipbreaker, the insert controls chip formation even when cut continuity varies, reducing the risk of built-up edge and spontaneous wear. This translates into steady part quality across batches and fewer tool indexings, a tangible benefit where repeatability and uptime are priorities.

Practical dimensions and workshop integration

Key dimensions such as the 12 mm size, 4.76 mm thickness and 0.8 mm corner radius make this insert suitable for a wide range of ISO holders and machining tasks. The 0° clearance and rhombic shape allow flexible approach angles for both external turning and light internal work. As part of a system, the insert is paired with an appropriate holder, support pad and replacement screws to form a stable tooling solution; matching the chipbreaker and grade to the workpiece material yields the best surface finish and tool life.

FAQ

Which materials is this insert optimised for? The Tungaloy CNMG120408 T9235 insert is optimised for machining steel, offering improved resistance to chipping and stable edge life in lower cutting speed applications.

How does the chipbreaker perform with interrupted cuts? The double-sided chipbreaker on this insert promotes controlled chip formation during interrupted cuts, helping to avoid built-up edge and to maintain consistent surface quality.

What must be checked for holder compatibility? Compatibility requires matching the ISO form, relief angle, tolerance class, mounting method, size and thickness; the CNMG120408 designation indicates the ISO geometry to be matched to the holder.

Can this insert be used for internal turning as well as external turning? Yes, the rhombic 80° geometry and 0° clearance make the insert suitable for both external turning and light internal applications when fitted in the proper ISO holder.

What are the key dimensional data to verify before ordering? Verify size (12 mm), thickness (4.76 mm), corner radius (0.8 mm), hole style (cylindrical) and included angle (80°) to ensure the insert matches the intended holder and application.
