CNMG 120408 TH10 indexable turning insert – Tungaloy

A CNMG120408 TH10 indexable insert for ISO-standard turning, designed for external and internal machining where low cutting forces and clean surfaces are required

• Rhombic CNMG geometry, 80° approach angle
• Uncoated carbide grade TH10 for low cutting forces
• Double-sided chipbreaker for reliable chip control
• Cylindrical hole for secure clamping in holders

Consistent chip control for predictable machining results

The CNMG120408 TH10 insert pairs a sharp, uncoated carbide edge with a double-sided chipbreaker to produce short, controllable chips in many turning operations. The chipbreaker geometry reduces entanglement and evacuation problems, which helps to maintain cycle times and minimise machine stoppages. In practice, this leads to a more stable process window and a reproducible surface finish when machining aluminium, brass and similar materials. The clear benefit is fewer interruptions and a predictable part quality that supports efficient production planning.

Broad material suitability and reduced cutting effort

The uncoated carbide grade TH10 is a universal, sharp grade intended for non-ferrous workpieces and applications that benefit from low cutting forces and clean surfaces. Compared with tougher, coated grades, this sort of cutting edge helps to avoid built-up edge when machining softer metals, improving surface integrity and reducing burr formation. For applications where minimal cutting resistance and good finish are priorities, the grade offers an economical alternative while maintaining acceptable tool life under appropriate cutting conditions.

Robust geometry and secure clamping for repeatable results

The insert features a rhombic geometry with an 80° approach angle and a 0.8 mm corner radius, providing a balance between edge strength and finishing capability. The insert thickness (4.76 mm) and cylindrical hole facilitate a secure clamp in ISO-compatible holders; the compatibility is determined by holder form, clearance angle, tolerance class, clamping method, size and thickness. Using the correct combination of holder and fastening hardware ensures repeatable clamping, accurate positioning and consistent cutting behaviour across production batches.

Practical integration and selection advice

The ISO designation and dimensional data make the insert straightforward to specify for existing tool systems: size 12 mm and the standard CNMG outline permit direct comparison with alternative inserts from other manufacturers. Selecting the appropriate chipbreaker and grade for the specific workpiece material and machining stability is the primary factor in achieving the desired balance between surface finish and productivity. For setups with constrained rigidity, the sharp TH10 grade yields lower cutting forces; where higher robustness is required, consider a different grade or edge preparation.

FAQ

What materials is this insert best suited for?
The CNMG120408 TH10 insert is intended primarily for non-ferrous materials and applications where a sharp, uncoated edge reduces cutting forces and improves surface quality.

Is the insert reversible or single-use per side?
The insert is double-sided with a chipbreaker on each side, allowing indexable reuse by rotating the insert to the fresh cutting edge as intended.

How is holder compatibility ensured?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; matching these parameters to the ISO designation ensures correct fit and stable clamping.

Can this insert be used for internal turning operations?
Yes; the geometry and chip control are suitable for both external and internal turning when used with an appropriate holder and stable setup.

What effect does the 0.8 mm corner radius have on the machined surface?
A 0.8 mm corner radius offers a compromise between edge strength and surface finish, improving edge life while producing a consistent finish in moderate feed ranges.
