CNMG120416 T9225 CNMG ISO turning insert – CVD-coated cemented carbide, 80° rhombic, 1.6 mm radius · Tungaloy

The CNMG120416 T9225 is an ISO rhombic turning insert engineered for robust medium-to-heavy steel turning, offering toughness for variable engagement and light interruptions.

• ISO‑standard rhombic geometry 80°
• CVD-coated cemented carbide grade T9225
• 1.6 mm corner radius for strength
• Double‑sided chipbreaker with hole

Consistent cutting performance with a robust universal grade

The combination of a CVD-coated surface and T9225 grade provides a balance of hardness and toughness suited to medium-to-heavy steel work. This composition promotes stable chip control and extended edge life under changing engagement conditions. The CVD coating reduces flank wear at elevated temperatures while the cemented carbide substrate maintains mechanical strength, making the insert a cost-effective option for productive runs where occasional interruptions occur. The overall effect is fewer tool changes and improved process efficiency in serial turning tasks.

Quick integration into ISO tool systems and repeatable clamping

Designed to ISO geometry, the insert matches holders when shape, relief angle, tolerance class, attachment, size and thickness align. The 0° relief angle, cylindrical hole and rhombic form simplify positioning and indexing in standard holders, while the 12 mm size and 4.76 mm thickness ensure dimensional stability. A system approach — insert, compatible external holder or boring bar, shim/clamp set and replacement screws — supports rapid changeovers and repeatable setup. The result is reduced setup time and predictable tool behaviour across shifts.

Practical guidance for turning strategies and edge use

For external and internal turning, select the double‑sided chipbreaker and a matching grade to suit material, operation and machine rigidity. The 1.6 mm corner radius increases edge strength and resists chipping in interrupted cuts, while the 80° included angle provides versatility for a range of diameters and profiles. Where finish is critical, moderate feeds and cooled cutting help exploit the coating’s wear resistance; where heavy stock removal is required, prioritise rigidity and stable clamping to maintain repeatable cutting conditions. Clear specification of the chipbreaker and grade helps avoid trial-and-error and shortens process qualification times.

FAQ

What materials is this insert best suited to?
The CNMG120416 T9225 insert is specified for medium-to-heavy steel machining; the T9225 grade and CVD coating give toughness and wear resistance suitable for variable engagement conditions.

Can the insert handle interrupted cuts?
Yes. The combination of the 1.6 mm corner radius and the T9225 grade provides additional edge strength for light to moderate interruptions during turning.

How is the insert secured in the holder?
The insert uses a cylindrical hole and standard ISO clamping arrangements; compatibility depends on matching form, relief angle, tolerance, attachment and thickness with the chosen holder.

Is the chipbreaker reversible and indexable?
The insert is double-sided with a chipbreaker on both faces, enabling indexing to a fresh edge and extending overall tool life.

Which components complete the system for use on the lathe?
A proper system includes the ISO insert, a compatible external holder or boring bar, an underlay/shim or clamp set and replacement screws to ensure stable clamping and repeatable positioning.
