CNMG120404 T5105 — Turning insert (CVD-coated carbide, rhombic 80°) by Tungaloy

The CNMG120404 T5105 is an ISO rhombic turning insert engineered for high-speed machining of cast iron under stable cutting conditions.

• CVD-coated carbide grade T5105 for high-speed cutting
• Rhombic 80° geometry, 0° clearance angle
• Double-sided insert with cylindrical hole
• Ideal for stable cast iron turning operations

Productive high‑speed cutting with durable CVD coating

The insert uses a CVD-coated carbide substrate in grade T5105, designed specifically to extend tool life during aggressive turning operations on cast iron. The CVD (chemical vapour deposition) coating forms a hard, wear‑resistant surface layer that reduces flank wear and improves thermal resistance at elevated cutting speeds. For production environments this translates into longer intervals between indexings and fewer tool changes, which helps maintain a smoother production flow and higher uptime. The wear characteristics of the grade mean cutting parameters can be pushed toward higher speeds while preserving surface quality.

Geometry and clamping that deliver consistent chip control

The rhombic CNMG shape with an 80° main cutting angle and a 0° relief provides a stable cutting edge for a range of turning tasks. The insert is double‑sided, offering two usable cutting edges per side, and features a cylindrical centre hole for secure locating and clamping in standard ISO holders. The 0.4 mm corner radius balances edge strength and surface finish; a larger radius increases robustness, while a smaller radius supports finer surface quality. The insert thickness of 4.76 mm contributes to rigidity in the tool system, reducing vibration and promoting consistent chip formation under stable set‑ups.

System compatibility and practical selection guidance

Compatibility with a selected holder is determined by shape, clearance angle, tolerance class, mounting method, size and thickness; these parameters ensure correct seating and repeatability. The typical system comprises the ISO insert, a matching external holder or boring bar, an underlay shim or clamping kit and the securing screws. For cast iron turning choose the appropriate chipbreaker type and the T5105 grade when process stability and wear resistance are priorities. Technical drawings or holder specifications should be consulted to confirm match in form and dimensions before assembly. If further technical data is needed, Metav Werkzeuge provides detailed guidance and material‑specific recommendations.

FAQ

What materials is this insert intended for?
The CNMG120404 T5105 insert by Tungaloy is optimised for high‑speed machining of cast iron under stable cutting conditions.

What does the T5105 designation indicate?
T5105 identifies the carbide grade and coating specification; it denotes a CVD‑coated carbide developed for wear resistance and thermal stability in high‑speed applications.

What is meant by CNMG120404?
CNMG120404 denotes the insert shape (CNMG), ISO size (12), thickness (4.76 mm) and corner radius (0.4 mm) — the ISO code 120404 corresponds to these geometric parameters.

Is the insert reversible and how many cutting edges are available?
Yes; the insert is double‑sided, providing multiple indexable cutting edges and a cost‑effective edge‑usage cycle.

How to ensure compatibility with a holder?
Compatibility depends on the insert form, clearance angle, tolerance class, mounting style, size and thickness; matching these dimensions with the holder specification ensures secure seating and repeatable performance.
