TNMG 160404 T515 Turning insert by Tungaloy — CVD-coated carbide for cast iron

The TNMG160404 T515 is an ISO-standard triangular turning insert designed for efficient external and internal turning of cast iron, offering stable chip control and reliable performance in interrupted and continuous cuts.

• TNMG triangular ISO turning insert T515
• CVD-coated carbide for cast iron machining
• 0.4 mm corner radius for controlled cutting
• Double-sided chipbreaker, cylindrical hole

Consistent chip control that boosts process stability

The insert’s CVD-coated carbide substrate and double-sided chipbreaker are engineered to promote consistent chip formation when machining cast iron, reducing the risk of workpiece damage and tool vibration. This technical combination results in improved surface finish and fewer unplanned tool changes, which contributes to higher overall productivity. The triangular geometry delivers multiple usable cutting edges, making the solution particularly economical for batch production and general turning tasks.

Precise geometry for reproducible results

With a defined 0.4 mm corner radius and 4.76 mm thickness, the insert provides predictable cutting behaviour under varying feed rates and depths of cut. The cylindrical hole and ISO form ensure compatibility with a wide range of ISO carriers and boring bars, simplifying tool inventory and set-up. These dimensional characteristics translate into reproducible part quality across shifts and operators, reducing scrap rates and setup verifications.

Application-focused design for everyday turning

Specified for turning operations, the insert’s triangular shape and 60° geometry enable efficient material removal in external and internal turning; the 0° clearance angle suits many standard toolholder designs. The grade is selected for economical machining of cast iron, balancing wear resistance and toughness for interrupted cuts and moderate cutting speeds. For workshops seeking predictable machining cycles, this insert offers a practical compromise between cost per edge and consistent tool life.

Integration and handling guidance for seamless use

The insert fits ISO-standard tool systems; selection of holder form, tolerance class and clamping method determines final compatibility. For best results, combine the insert with a rigid holder, appropriate clamping seat and correct screw torque. Where vibration or chatter is present, reducing overhang and selecting a more positive chipbreaker geometry will enhance stability. For specific process windows, Metav Werkzeuge can provide cutting data suggestions based on workpiece material and machine capability.

FAQ

What materials is this insert best suited for?
The TNMG160404 T515 is formulated for economical machining of cast iron, using a CVD-coated carbide grade to balance wear resistance and toughness in standard turning operations.

Is the insert compatible with standard ISO toolholders?
Yes. The TNMG160404 follows ISO geometry and fits ISO-compatible external holders and boring bars; holder form, clearance and clamping must match the insert’s dimensions.

How many cutting edges are available per insert?
The triangular shape provides multiple usable edges; the precise count depends on the insert orientation and whether both sides of the chipbreaker are employed.

What advantages does the CVD coating deliver?
The CVD-coated carbide offers improved wear resistance and thermal stability during cutting, which supports longer edge life and consistent performance when machining cast iron.

Can this insert handle interrupted cuts?
The T515 grade and robust chipbreaker design are suited to interrupted cutting conditions typical in turning, offering stable performance under moderate interruptions.

How should the insert be clamped?
Use a compatible ISO holder with appropriate clamping seat and torque; the cylindrical hole supports secure fastening and precise positioning in most standard clamping systems.
