TNMG160412 T9225 Turning Insert — CVD‑coated carbide, 60° triangular (Tungaloy)

A TNMG160412 T9225 triangular turning insert designed for medium‑to‑heavy steel machining, compatible with ISO toolholder systems and featuring a double‑sided chipbreaker.

• TNMG160412 geometry, 60° triangular insert
• CVD‑coated carbide grade T9225 for steel
• 1.2 mm corner radius for stable cutting
• Double‑sided chipbreaker, cylindrical hole

Consistent productivity through CVD coating and carbide core

The CVD‑coating combined with a carbide substrate delivers improved wear resistance and edge life, which translates into fewer indexings and longer tool cycles. For industrial turning applications this means a measurable reduction in downtime and more predictable production output. The coating chemistry enhances heat resistance under higher cutting speeds, while the substrate maintains toughness under interrupted or variable cutting conditions, providing a balance between durability and fracture resistance.

Geometry tailored for surface quality and chip control

The 60° triangular form with a 1.2 mm corner radius and a double‑sided chipbreaker is configured to promote stable cutting and controlled swarf formation during external and internal turning. The rounded corner reduces peak loads at entry, lowering the risk of edge chipping, while the chipbreaker shapes chips to aid evacuation and protect the cutting edge. The result is a more consistent surface finish and reduced machine stoppages for chip clearing, particularly beneficial when machining medium‑to‑heavy steel under variable engagement conditions.

ISO compatibility for straightforward toolroom integration

As an ISO‑standardised insert, the TNMG160412 T9225 fits into existing ISO toolholder ecosystems; compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness. Typical system components include the insert, a matching external holder or boring bar, a shim/clamping set and replacement screws, enabling quick replacement and minimal setup time. Selecting the correct chipbreaker and grade according to workpiece material and cutting strategy ensures process stability and cost‑effective machining across batch sizes.

FAQ

Is this insert suitable for turning steel?
Yes. The TNMG160412 T9225 insert is a robust universal grade intended for medium‑to‑heavy steel machining, offering good wear resistance and toughness.

What does the T9225 grade indicate?
T9225 denotes a CVD‑coated carbide grade engineered for stable performance in steel machining, combining heat resistance with enough toughness for variable cutting conditions.

How is the insert secured in the toolholder?
The insert features a cylindrical hole and is clamped in ISO‑compatible external holders or boring bars; a shim/clamp set and replacement screws complete the system.

Which cutting geometry benefits does the 1.2 mm radius provide?
A 1.2 mm corner radius reduces load peaks at engagement, improves edge strength for interrupted cuts and supports a consistent surface finish with fewer chippings.

Can the chipbreaker handle interrupted cuts?
Yes. The double‑sided chipbreaker is designed to control chip formation and evacuation, improving process reliability during interrupted or variable cutting.
