CNMG 120404 T9235 ISO turning insert for turning — Tungaloy

The CNMG120404 T9235 is an ISO rhombic turning insert designed for external and internal turning, offering a tough grade for steel under lower cutting speeds and interrupted cuts.

• CVD-coated carbide grade T9235
• Designed for unstable cutting conditions
• Double-sided chipbreaker for chip control
• ISO rhombic insert with cylindrical hole

Consistent chip control and durable cutting edge

The CNMG120404 T9235 combines a CVD‑coated surface with a carbide substrate to extend edge life and resist flank wear in demanding applications. The double‑sided chipbreaker is engineered to deliver predictable chip formation, reducing the risk of built‑up edge and improving surface finish when turning steels. This results in fewer tool changes and more reliable cycle times on batch and single‑piece production, making the component a cost‑effective choice where process stability is a priority.

Suited to unstable and interrupted machining

The T9235 grade is formulated as a tough grade for steel, explicitly intended for lower cutting speeds and situations with strong interruptions or variable clamping. Under these conditions, the insert’s geometry and coating combination help absorb shock and avoid premature chipping, which supports longer tool life and consistent part quality. For shops facing frequent chatter or interrupted cuts, this insert offers a pragmatic balance between wear resistance and fracture toughness.

ISO compatibility and secure mounting for quick tool changes

As an ISO‑standard indexable plate, compatibility with a toolholder depends on form, clearance, tolerance class, fastening and thickness; the rhombic shape, 80° cutting angle and 0° clearance must be matched to the selected holder. The insert features a cylindrical hole for positive clamping and a 0.4 mm corner radius, while the plate thickness of 4.76 mm and size 12 mm conform to ISO limits for this designation. Verifying these dimensions against the holder drawing ensures repeatable seating and optimised cutting conditions.

Practical advantages for workshop productivity

In production environments the insert’s ISO form and standard screw hole support fast stock rotation and predictable logistics. The combination of CVD‑coated protection and a robust chipbreaker reduces downtime from edge failures and improves first‑pass yields, which enhances throughput without sacrificing part quality. Operators gain confidence from consistent chip evacuation and the insert’s capacity to withstand interrupted cuts, while engineers benefit from clear specification data for process planning.

FAQ

Which materials is this insert intended for?
The CNMG120404 T9235 insert from Tungaloy is primarily specified for machining steel, especially where interrupted cuts or unstable conditions occur; refer to SKU TUN6785910 when enquiring about process limits.

How is holder compatibility determined?
Compatibility depends on insert form, clearance, tolerance class, fastening type, size and thickness; the CNMG120404 has a rhombic form, 80° angle and a cylindrical hole, so match these dimensions to the chosen holder and clamping set.

What benefits does the CVD coating provide?
A CVD‑coated surface on the carbide substrate improves wear resistance and maintains edge integrity under thermal and abrasive loads, contributing to longer tool life in turning operations on steel.

Can the insert be indexed for multiple edges?
Yes, the double-sided design allows indexing to a fresh cutting edge, offering economical use of the plate and reduced frequency of replacements.

What is the corner radius and why does it matter?
The corner radius is 0.4 mm, which balances edge strength and surface finish; a larger radius improves edge robustness, while a smaller radius favours finer surface quality.
