TNMG160412 T9225 TNMG turning insert — CVD-coated carbide, 1.2 mm radius | Tungaloy

A TNMG160412 T9225 turning insert engineered for medium-to-heavy steel turning, offering a triangular form with a cylindrical hole and a double-sided chipbreaker for reliable clamping and chip control.

• ISO‑standard triangular insert TNMG160412
• CVD-coated carbide grade T9225 for toughness
• 1.2 mm corner radius for robust edge life
• Double‑sided chipbreaker with cylindrical hole

Consistent cutting performance for demanding steel work

The CVD-coated cemented carbide construction delivers a balance of wear resistance and fracture toughness that suits mixed and interrupted cuts in steel. As a CVD-coated grade, the coating reduces abrasive wear at elevated temperatures while the substrate maintains the ability to resist chipping under variable engagement. This combination supports longer effective tool life and fewer insert changes, which contributes directly to improved process efficiency and lower downtime during production runs.

Designed for secure clamping and system compatibility

Manufactured to ISO dimensions, the insert is intended for integration into established turning systems; compatibility depends on form, 0° clearance angle, tolerance class, clamping method, size and thickness. The cylindrical hole and the triangular plate form simplify positioning and secure attachment in most TNMG-compatible holders. With a 16 mm inscribed circle and 4.76 mm plate thickness, the geometry ensures positional stability during external and internal turning operations, making the insert suitable for standard clamping sets, shims and retaining screws.

Edge geometry that improves stability and surface finish

The 1.2 mm corner radius increases the edge strength and reduces the tendency for edge failure when heavy cuts or slight interruptions occur. Combined with the double-sided chipbreaker, the geometry promotes controlled chip formation and evacuation, which reduces built-up edge and vibration. For semi-finishing and roughing passes, this arrangement enhances process reliability; for finishing, modest feed adjustments preserve surface quality while benefiting from the insert’s robust edge.

Practical application advice and process benefits

Select the double-sided chipbreaker and the T9225 grade when facing variable engagement or slightly interrupted cuts in steel; this yields a reliable compromise between productivity and reproducible tool life. Adjust cutting speeds to suit the CVD-coated substrate and prioritise stable clamping to exploit the insert’s strengths. The design supports both external and internal turning tasks and is particularly effective when paired with a rigid holder and appropriate coolant strategy to maintain thermal stability and chip flow.

FAQ

What steels is this insert suited for?
The TNMG160412 T9225 insert is optimised for medium-to-heavy steel turning, delivering a robust balance of wear resistance and toughness for varying engagement conditions.

How does the corner radius affect cutting?
A 1.2 mm corner radius on the TNMG160412 provides a stronger cutting edge, improving resistance to edge chipping and aiding stability during heavier passes.

Is this insert reversible or single‑edged?
This triangular insert is double-sided with a chipbreaker on both sides, allowing the plate to be indexed to fresh cutting edges as they wear.

Which holders are compatible with this ISO insert?
Compatibility is determined by the holder’s form, tolerance, frets/clearance and clamping arrangement; the ISO-standard dimensions of the TNMG160412 support use in most TNMG-compatible turning holders and boring bars.

What advantages does the T9225 grade provide?
The T9225 CVD-coated carbide grade offers a versatile, tough solution for steel machining, performing well under interrupted cuts and providing consistent tool life across a range of turning conditions.
