TNMG160412 T9225 Turning Insert (ISO) by Tungaloy — 60° triangle, CVD-coated

TNMG160412 T9225 is an ISO‑standard turning insert designed for external and internal turning operations where robustness and chip control under variable engagement are required.

• ISO‑standard triangular insert
• CVD‑coated carbide grade T9225
• 60° included angle, 1.2 mm radius
• Double‑sided chipbreaker with cylindrical hole

Consistent cutting performance for mixed steel conditions

The CVD‑coated carbide composition of this grade, marked T9225, is engineered as a robust universal solution for medium to heavy steel machining. The coating increases wear resistance while the substrate retains necessary toughness for mildly interrupted cuts. As a result, the insert delivers longer tool life and more consistent pass‑to‑pass dimensional stability, which supports higher utilisation rates on production lathes and reduces unscheduled tool changes.

Geometry and clamping designed for productivity

The triangular TNMG form with a 60° included angle and 1.2 mm corner radius provides a balance between strength and accessibility in shoulder and profile turning. The double‑sided chipbreaker and cylindrical hole enable secure clamping in compatible ISO holders and permit economical use of both cutting edges. A plate thickness of 4.76 mm and a plate size of 16 mm support stable cutting conditions and predictable cutting forces, contributing to repeatable surface quality.

Interchangeability and chip control for efficient processes

Being an ISO turning insert ensures interchangeability across standard holders; compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness. The integrated chipbreaker is suitable for a wide range of steel conditions; selecting the chipbreaker and grade according to workpiece stability further enhances chip control and minimises interruptions. The system approach—insert, appropriate external holder or boring bar, backing/clamping kit and spare screws—supports rapid replacement and reduces spindle downtime.

Practical application guidance for improved outcomes

Intended primarily for turning, the insert performs well in both external and internal operations when matched with the correct holder and cutting parameters. The universal nature of the T9225 grade makes it a good starting point where engagement conditions vary or where occasional interrupted cuts occur. Correct selection of feed, depth of cut and cutting speed according to material and machine rigidity will help achieve a better surface finish and reduced downtime, while leveraging the insert’s toughness and wear resistance.

FAQ

What materials is this insert best suited for?
The TNMG160412 T9225 insert is formulated for medium to heavy steel machining and performs reliably under variable engagement conditions, offering a balance of toughness and wear resistance.

Can the insert be used on both external and internal turning operations?
Yes, the ISO‑standard geometry and triangular shape allow the TNMG160412 to be used for external and many internal turning tasks when paired with a suitable holder and correct cutting parameters.

How does the double‑sided chipbreaker influence tool life?
The double‑sided chipbreaker on this Tungaloy insert provides improved chip control and allows economical use of both cutting edges, which typically extends effective tool life and reduces changeover frequency.

What does the 1.2 mm corner radius mean for the component finish?
A 1.2 mm corner radius offers a compromise between edge strength and surface interaction; it helps achieve stable cutting and a consistent surface finish, especially in medium‑depth passes.

Is the TNMG160412 compatible with standard ISO holders?
Yes, the insert follows ISO dimensions; compatibility depends on holder form, clearance, tolerance class, fastening type, size and thickness, so matching these parameters ensures correct fit and clamping security.
