DNMG 110404 T5115 — Indexable turning insert, 55° approach angle, Tungaloy

DNMG110404 T5115 is a rhombic ISO indexable turning insert designed for turning applications in cast iron, offering a balanced mix of wear resistance and cutting-edge stability

• ISO‑standard rhombic insert
• CVD‑coated cemented carbide grade T5115
• 55° approach angle for versatile turning
• Double-sided chipbreaker for extended life

High‑performance grade for cast‑iron turning that reduces downtime

The T5115 grade is a CVD‑coated cemented carbide developed as a universal solution for machining cast iron. The CVD coating provides enhanced surface hardness and wear resistance, which translates into longer tool life and fewer indexings compared with uncoated grades. For production environments where consistent component quality and predictable tool consumption matter, this insert helps maintain cycle times by delivering stable cutting conditions and repeatable edge performance.

Geometry and chip control designed for productive machining

With a rhombic plate form and a 55° approach angle, the insert offers an effective compromise between cutting-edge strength and access to profiles. The double‑sided chipbreaker allows two usable cutting edges per face, improving economics and ensuring controlled chip formation during external and internal turning. A 0.4 mm corner radius supports smoother finishes on interrupted cuts while preserving edge stability on heavier cuts, making it suitable for typical roughing and finishing passes in cast‑iron components.

System compatibility and installation guidance for smooth set‑up

Compatibility with toolholders depends on form, relief angle, tolerance class, fastening and the insert’s size and thickness. The DNMG format is widely supported by external holders and boring bars; a typical system comprises the ISO insert, a matched external holder or boring bar, an underlay/clamp set and replacement screws. The insert’s cylindrical hole ensures positive location and simple clamping in standard DNMG seats, streamlining changeovers and minimising setup errors on the shop floor.

Practical benefits and process reliability in daily production

Choosing a CVD‑coated grade such as T5115 emphasises process reliability: the coating and substrate combination promotes stable wear progression and optimised chip control, which reduces rework and improves surface integrity of cast‑iron parts. The compact plate dimensions and 4.76 mm plate thickness contribute to rigidity in the clamped system, while the standardised ISO geometry supports easy stock management and quick replacement, helping to keep machines running and production schedules on track.

FAQ

What materials is this insert optimised for?
The Tungaloy DNMG110404 T5115 insert is optimised for machining cast iron, offering a balanced combination of wear resistance and cutting edge stability suitable for common grey and nodular cast‑iron alloys.

Can this insert be used in standard DNMG holders?
Yes, the insert follows ISO geometry for DNMG formats; compatibility is determined by form, relief angle, tolerance and clamping method, so pairing with a matching DNMG external holder or boring bar is recommended.

What advantage does the CVD coating provide?
The CVD coating on the T5115 grade increases surface hardness and wear resistance, which helps to extend tool life and maintain consistent cutting performance on abrasive cast‑iron materials.

How does the 0.4 mm corner radius affect finish and strength?
A 0.4 mm radius offers a compromise between surface finish and edge robustness: it smooths the cutting action for improved surface quality while retaining enough edge strength for light to medium roughing passes.

Is the insert reversible and how many cutting edges are available?
The rhombic DNMG insert is double‑sided with a double‑sided chipbreaker, providing multiple indexable edges per plate to improve economy and reduce tool change frequency.
