TNMG160412 T9225 TNMG indexable turning insert, CVD-coated carbide, 60° triangle — Tungaloy

A TNMG160412 T9225 indexable insert designed for external and internal turning, offering a tough CVD-coated carbide grade suited to interrupted cuts and varying engagement conditions

• CVD-coated carbide for wear resistance
• Robust universal grade for medium to heavy steel
• Double-sided insert with 60° triangle form
• Cylindrical hole for secure fastening

Consistent cutting performance for medium to heavy steel

The insert is engineered to deliver stable cutting under fluctuating conditions typical of steel turning. The T9225 grade combines toughness and wear resistance, which reduces edge chipping during interrupted cuts and when machining mixed sections. As an indexable insert, it allows quick indexation and minimal downtime, supporting predictable cycle times and improved process reliability for series production and job-shop environments.

Durable coating and material for extended tool life

The CVD-coated surface on the carbide substrate improves wear resistance at elevated temperatures and secures cutting-edge integrity over longer runs. This coating is particularly valuable when switching between roughing and semi-finishing tasks, because it slows flank wear without sacrificing toughness. The result is fewer insert changes and more efficient use of machine time, especially when the cutting parameters or workpiece geometry require resilience rather than extreme hardness.

Secure clamping and straightforward compatibility with holders

Compatibility with toolholders is determined by form, clearance angle, tolerance class, clamping method, size and thickness. The triangular 60° geometry and the cylindrical hole provide secure engagement in standard external holders and boring bars, while the 4.76 mm thickness and defined tolerance enable consistent seating. This predictable fit reduces vibration and improves surface finish during both external turning and internal turning operations.

Geometry optimised for interrupted cuts and versatile use

The double-sided chipbreaker geometry and the corner radius 1.2 mm combine to balance edge strength and load distribution, making the insert suitable for roughing passes with variable chip loads. The triangular shape grants three indexed cutting edges per side, increasing usable life before disposal. For shops seeking a single, multi-purpose grade for a broad range of steel machining tasks, this geometry and the T9225 grade offer a practical compromise between productivity and robustness.

FAQ

What materials is this insert best suited for?
The Tungaloy TNMG160412 T9225 insert is optimised for machining steel and is a robust universal solution for medium to heavy steel turning.

Can the insert handle interrupted cuts?
Yes, the T9225 grade and the insert geometry are designed to absorb shock and resist edge chipping during light to moderate interruptions.

Which holders are compatible with this triangular insert?
Compatibility depends on form, clearance angle, tolerance class, clamping, size and thickness; the TNMG160412 fits standard ISO triangular holders with matching dimensions.

How does the CVD coating benefit machining?
The CVD-coated layer improves wear resistance at higher temperatures, extending edge life across mixed cutting conditions and reducing flank wear during longer cycles.

Is the insert double-sided and how does that affect cost-efficiency?
The insert is double-sided, providing multiple indexed edges and increasing usable life before replacement, which supports higher cost-efficiency in regular production.
