TNMG220416 T5115 TNMG turning insert for turning, Tungaloy

A TNMG220416 T5115 triangular ISO insert designed for reliable external and internal turning of cast iron components with a universal CVD-coated carbide grade.

• TNMG geometry with 60° cutting angle
• CVD-coated carbide grade T5115
• Universal for cast iron machining
• Double-sided chipbreaker, cylindrical hole

Consistent productivity for cast iron turning

The combination of T5115 and a CVD-coated carbide substrate delivers a balanced mix of wear resistance and cutting-edge stability, optimised for cast iron. The 1.6 mm corner radius increases edge strength, reducing the frequency of edge chipping under interrupted cuts and contributing to longer uninterrupted production runs. Where runout and chatter are concerns, the 60° insert geometry offers predictable engagement and a favourable force direction, improving tool life and part consistency.

ISO compatibility for rapid integration into tool systems

Supplied as an ISO-standard triangular insert, the part fits compatible external holders or boring bars; compatibility is determined by shape, relief angle, tolerance class, clamping method, size and thickness. The TNMG220416 form, 0° relief and a 4.76 mm thickness ensure a solid connection in the pocket, while the cylindrical hole and matching clamping set provide secure fixation for heavy cuts. This standardisation enables fast changeover and simplified inventory management in mixed-machine environments.

Practical handling and cost-efficient reuse

The insert is double-sided with a chipbreaker designed for general-purpose cast-iron work, offering multiple indexed cutting edges for economical use. The triangular shape and durable substrate mean each insert can be re-indexed, lowering cost per edge compared with brazed cutters. The moderate plate size (22 mm) and robust plate thickness support higher feeds without compromising stability, making the solution suitable for both finishing and semi-finishing passes where surface quality and productivity matter.

Choosing the right combination for reliable results

Select the chipbreaker and grade in line with material condition and machining stability: the universal T5115 grade is formulated for broad cast iron coverage, balancing edge toughness and wear resistance. For best outcomes, match feed and depth of cut to machine stiffness and workpiece setup, and consider the insert’s geometry when specifying holders. If parameter selection or process validation is required, technical guidance and cutting data are available to ensure repeatable results and minimal downtime.

FAQ

What materials is this insert suited for?
The TNMG220416 T5115 insert is a CVD-coated carbide grade formulated as a universal grade for cast iron machining, providing a balance of wear resistance and edge stability.

How is the insert mounted in a tool system?
The insert fits ISO-standard pockets and is secured via its cylindrical hole with the appropriate backing pad, clamp set and screw in compatible external holders or boring bars.

How many times can the insert be indexed?
The double-sided triangular design provides multiple indexed cutting edges, enabling several reuses before disposal, which reduces cost per usable edge.

What is the benefit of the 1.6 mm corner radius?
A 1.6 mm corner radius increases edge strength for interrupted or heavy cuts and contributes to a more robust cutting edge with improved surface results on cast iron.

Is this insert compatible with ISO tooling systems?
Yes, the insert is part of an ISO insert series and is designed for compatibility with holders and clamping systems that accept the TNMG220416 form.
