TNMG 160404 T9225 triangular indexable insert for Turning by Tungaloy – CVD-coated carbide, 0.4 mm radius

The TNMG160404 T9225 is an ISO-standard triangular indexable insert designed for external and internal turning applications, offering a robust universal grade for medium to heavy steel machining.

• CVD-coated carbide grade T9225
• Robust universal grade for medium–heavy steel
• Triangular shape with 0.4 mm corner radius
• Double-sided chipbreaker, central cylindrical hole

Maximise machining stability and tool life with a tough, coated grade

The CVD-coated T9225 carbide grade combines wear resistance with increased toughness to meet varying engagement conditions and lightly interrupted cuts. As a robust universal solution, the grade is formulated to maintain edge stability under load, reducing flank wear and extending usable life. The combination of coating and substrate results in consistent performance across a broad range of steels, which translates into fewer insert changes and improved process reliability when turning demanding batches.

ISO compatibility reduces setup uncertainty and saves time

Manufactured to ISO dimensions and tolerances, this triangular insert ensures predictable fit and secure clamping in compatible holders. The triangular geometry with a central cylindrical hole and a thickness of 4.76 mm provides reliable seat location and repeatability; the 60° included angle and 0° clearance angle fit standard holder families. Clear specification of form, rake angle and tolerance class supports quick selection of a matching external holder or boring bar, lowering setup times and minimizing unexpected tool changes.

Improved chip control and surface quality in steel turning

The double-sided chipbreaker is engineered to deliver controlled chip formation during a wide range of turning conditions, helping to avoid entangling or long stringy chips. Predictable chip flow decreases the risk of workpiece damage and optimises coolant access, which often leads to a superior surface finish and reduced secondary operations. For operators less familiar with chipbreaker design, this means more consistent parts and fewer interruptions for chip handling or manual intervention.

Practical application guidance for reliable results

Choose the chipbreaker and grade to match the workpiece material, type of cut and the machine–workpiece–toolset stability. The insert is particularly appropriate where interrupted cuts or variable engagement demand extra toughness rather than the highest possible hardness. When combined with a correctly specified holder and clamping set, the system—ISO insert, holder, shim and clamp—delivers repeatable performance and simplifies inventory management across turning operations. For bespoke process recommendations, detailed specifications are available on request.

FAQ

What materials is this insert best suited for?
The Tungaloy TNMG160404 T9225 insert is intended primarily for medium to heavy steel machining where a combination of wear resistance and toughness is required.

Is the insert reversible or indexable?
This triangular indexable insert is double-sided, allowing rotation to a fresh cutting edge and offering economical use of the insert body.

What are the key dimensions to check when selecting a holder?
Verify the insert size (16 mm inscribed circle), thickness (4.76 mm), hole style (cylindrical) and the ISO designation TNMG160404 to ensure correct fit and clamping with the chosen holder.

How does the chipbreaker affect machining performance?
The double-sided chipbreaker improves chip control across a range of feeds and depths of cut, which supports stable cutting, reduced rework and better surface finish during turning operations.

Can this insert handle interrupted cuts?
Yes, the T9225 grade offers increased toughness and is suitable for conditions with light interruptions or variable engagement that require a robust edge.
