TNMG 220408 T5115 TNMG turning insert for Drehen, CVD-coated carbide by Tungaloy

TNMG 220408 T5115 is an ISO-format triangular turning insert designed for external and internal turning operations, offering a balanced combination of wear resistance and cutting-edge stability for cast iron machining.

• CVD-coated carbide for reliable wear resistance
• Designed for cast iron with balanced edge stability
• Triangular ISO insert with cylindrical centre hole
• Double-sided chipbreaker for versatile turning

Increased process reliability through modern coating and grade selection

The T5115 grade is a CVD-coated carbide chosen for its balanced performance when machining cast iron, providing a compromise between wear resistance and edge stability that supports productive cutting cycles. The applied coating reduces flank wear in continuous operations, while the substrate retains toughness to resist chipping under intermittent cutting. For production environments requiring repeatable results, the combination of coating and substrate contributes directly to longer tool life and fewer insert changes, which lowers process interruptions and improves overall throughput.

ISO compatibility and cost-efficient system integration

Supplied in the standard ISO geometry, the triangular TNMG shape with a cylindrical centre hole ensures compatibility with a wide range of external holders and boring bars, subject to matching form, relief angle, tolerance class, clamping method, size and thickness. The insert is double-sided with two usable cutting edges per side, enabling economical indexing and reducing tooling costs per cutting edge. When selecting a holder, ensure the seating and clamping match the insert’s geometry and the specified relief angle to maintain accuracy and repeatability in the clamping interface.

Practical performance in typical turning applications

With a nominal cutting edge angle of 60° and a corner radius of 0.8 mm, this insert suits a variety of tasks from light finishing to medium-duty profiling in cast iron. The double-sided chipbreaker supports controlled chip formation across common depth-of-cut ranges, improving evacuation and reducing the risk of built-up edge. Integrating this insert into a system of appropriate holder stability and cutting parameters enhances surface quality and dimensional consistency, helping to meet production tolerances while maintaining efficient material removal.

FAQ

What materials is this insert optimised for? The T5115 grade is formulated for cast iron machining, providing a balance of wear resistance and edge stability suitable for grey and nodular cast irons.

How does the double-sided chipbreaker benefit production? A double-sided chipbreaker doubles the available cutting edges before indexing, meaning the insert can be rotated for fresh edges while maintaining consistent chip control and process stability.

Is the TNMG 220408 compatible with all ISO holders? Compatibility depends on matching the insert form, the 0° relief angle, tolerance class, clamping arrangement, size and thickness with the holder; the insert’s ISO geometry and cylindrical hole are standard features that facilitate selection.

What cutting edge radius should be chosen for finishing? The available corner radius of 0.8 mm provides a compromise between edge strength and surface finish; for finer finishes, a smaller radius would be preferable if available in the tool programme.

What is the manufacturer article number and SKU for ordering? The manufacturer article number is 6850307 and the manufacturer SKU is TUN6850307 for ordering and stock identification.
