CNMA 120416 T9205 — CNMA turning insert for steel, 80° rhombic, 1.6 mm radius (Tungaloy)

CNMA 120416 T9205 is an ISO-format rhombic indexable insert engineered for external and internal turning of steel under stable, higher-speed machining conditions.

• ISO rhombic CNMA 120416 geometry, 80° approach angle
• CVD-coated T9205 grade for wear resistance
• 1.6 mm corner radius for robust cutting edge
• Central cylindrical hole for secure clamping

Longer tool life through advanced coating technology

The insert uses a CVD-coated carbide grade T9205, which provides a durable, wear-resistant layer optimised for turning steel at elevated speeds. The coating reduces flank wear and helps maintain dimensional accuracy over longer tool cycles, which in turn improves process economy and lowers tool-change frequency. For production-focused workshops, this means fewer interruptions and a more predictable tool-life curve — a clear advantage where consistent part quality and uptime are priorities.

Geometry and clamping that improve stability and accuracy

The rhombic CNMA form with an 80° approach angle and a 1.6 mm corner radius offers a balance between versatility and edge strength. The insert’s central cylindrical hole enables positive clamping in compatible holders, while the specified relief angle of 0° ensures the correct clearance for conventional turning setups. Compatibility with a holder depends on shape, clearance angle, tolerance class, fastening method, size and thickness; selecting a matching seat and screw ensures repeatable positioning and maximises cutting stability for both external and internal operations.

Process-focused benefits for productive turning

Designed for productive machining under stable conditions, the grade performs well where consistent chip formation and edge integrity are required. The absence of an integrated chipbreaker indicates the insert is best paired with a holder or cutting strategy that manages chip flow according to the workpiece material and cutting parameters. In practical terms, the insert is particularly suitable for medium to high cutting speeds on steel components where surface finish and tool life are key performance indicators.

FAQ

What materials is this insert suited for?
The CNMA 120416 T9205 turning insert is specified for productive machining of steel under stable conditions; its CVD-coated T9205 grade provides wear resistance tailored to such applications.

How does the insert secure in the holder?
Clamping depends on form, clearance angle, tolerance class, fastening, size and thickness; the central cylindrical hole on this insert allows secure location and clamping when paired with a compatible CNMA seat and screw.

Is there a chipbreaker on this grade?
This variant is supplied without a chipbreaker, so chip control should be managed via cutting parameters or by using a holder equipped with a suitable chip-control top.

What are the critical dimensions to check before ordering?
Key dimensions are ISO designation CNMA120416, size 12 mm, thickness 4.76 mm, corner radius 1.6 mm and an 80° approach angle — verify holder compatibility against these values.

Can this insert be used for internal as well as external turning?
Yes; the insert is suitable for both external and internal turning provided the machining conditions are stable and the correct holder geometry is selected.

What performance benefits does the T9205 grade deliver?
The T9205 grade offers enhanced wear resistance and stable chip formation for higher cutting speeds on steel, supporting longer tool life and consistent surface quality.
