CNGG120408 TH10 CNGG – Indexable turning insert, 0° clearance, rhombic, Tungaloy

The CNGG120408 TH10 indexable insert for turning provides a sharp, uncoated carbide edge optimised for non-ferrous metals and applications requiring low cutting forces and clean surfaces.

ISO‑compliant rhombic insert design Sharp uncoated carbide edge for low cutting forces Double‑sided chipbreaker for extended use Compatibility with standard ISO holders and mounting

Precise geometry for dependable ISO‑compliant performance

The rhombic insert geometry and ISO designation ensure consistent fitment in standard holders; compatibility depends on form, relief angle, tolerance class, fastening and thickness rather than proprietary dimensions. The CNGG120408 family follows ISO norms for turning inserts, which simplifies tool selection and reduces set‑up time. With a defined approach angle of 80° and a nominal clearance of 0°, the geometry supports stable outer and inner turning where controlled chip flow and predictable contact conditions are required.

Sharp uncoated grade for low cutting forces and clean finishes

The uncoated carbide grade TH10 is a sharp, universal grade intended for non‑ferrous materials and operations where a clean cutting edge reduces built‑up edge and surface distortion. An uncoated cutting edge lowers friction in many alloys, producing lower cutting forces and improved surface integrity without relying on coating lubricity. The insert features a double‑sided chipbreaker, which helps to control chip form and contributes to consistent surface finish and reduced cycle time in serial production.

Practical benefits: cost‑efficient use and system flexibility

Using a reversible, double‑sided insert reduces tooling cost per edge and allows quick indexation for renewed cutting conditions. The plate thickness of 4.76 mm, the 0.8 mm corner radius and the 12 mm plate size balance edge strength with accessibility in tight turning operations. Where stability is limited, select the appropriate chipbreaker and grade to match workpiece material and feed; the ISO format makes it straightforward to find compatible external holders or boring bars and to replace only the insert when worn rather than the complete tool body.

FAQ

What materials are best suited to this insert?
The CNGG120408 TH10 insert is optimised for non‑ferrous materials and applications where a sharp, uncoated edge supports low cutting forces and clean surface results.

How does the TH10 grade perform compared with coated grades?
TH10 is an uncoated carbide grade that delivers lower cutting forces and reduced built‑up edge on many alloys; coated grades can offer wear resistance at the expense of initial edge sharpness.

Can this insert be used for both external and internal turning?
Yes, the ISO rhombic form and the hole for secure clamping make the insert suitable for both external and internal turning when paired with the correct holder.

What are the key dimensional references for holder selection?
Use the ISO designation CNGG120408, plate thickness 4.76 mm, plate size 12 mm and corner radius 0.8 mm to select a compatible holder and clamping set.
