SNMG 120408 TH10 — ISO‑standard turning insert for external and internal turning by Tungaloy

SNMG120408 TH10 is an ISO‑standard square indexable insert for turning, designed for non‑ferrous and similar applications where a sharp, uncoated cutting edge delivers low cutting forces and fine surface finish.

• ISO square insert SNMG 120408
• Uncoated cemented carbide grade TH10
• Double-sided chipbreaker for clean chips
• 0° clearance for stable, low-force cutting

High-efficiency turning where consistent surface quality matters

The SNMG120408 TH10 indexable insert is optimised for operations that prioritise low cutting forces and superior surface quality. The uncoated cemented‑carbide composition and the sharp TH10 grade reduce the tendency for built‑up edge on non‑ferrous materials, which in turn supports a more reliable finish and longer effective tool life under light to medium cutting conditions. The integrated double‑sided chipbreaker assists in producing short, controllable chips that improve process stability and reduce downtime associated with chip management.

Precision fit and straightforward tool selection for ISO holders

Compatibility with the toolholder is determined by geometric form, clearance angle (0°), tolerance class, mounting style, size and thickness. The ISO designation ensures the insert seats correctly in standard clamping systems when the correct seat and clamping set are chosen. Specifying the square geometry and the cylindrical hole provides a secure attachment and repeatable positioning, so the clamping torque and insert orientation deliver consistent cutting conditions across batches.

Material behaviour and why an uncoated edge can be advantageous

For many non‑ferrous components and finishing passes, an uncoated cemented‑carbide edge performs better than coated alternatives because it presents a sharper initial cutting edge and lower friction in certain material pairings. The TH10 grade is a universal, sharp grade formulated to support clean surfaces and low cutting forces; it is especially suitable where coatings might promote built‑up edge or when fine surface standards are required. This results in predictable tool behaviour and facilitates process planning in production environments.

Practical chip control and handling in production

The insert’s corner radius (0.8 mm) and square form offer a balance between edge strength and detail capability, making it suitable for both light profiling and routine turning operations. The listed thickness (4.76 mm) and 12 mm size provide a stable seating in the holder, reducing vibration and helping to maintain tolerance. The double‑sided chipbreaker eliminates the need for immediate reorientation and doubles the usable life per index, supporting continuous production and lower tooling costs per part when the correct feed and speed are applied.

FAQ

Which materials are best suited for this insert?
The SNMG120408 TH10 insert is intended primarily for non‑ferrous materials and applications where an uncoated cemented‑carbide edge supports low cutting forces and clean surface outcomes.

How is holder compatibility ensured?
Compatibility is defined by insert form, clearance angle, tolerance class, mounting style, size and thickness; selecting an ISO‑compatible holder and the correct clamping set will ensure repeatable seating for the SNMG120408 insert.

Is the cutting edge coated?
No, the TH10 grade on this indexable insert is uncoated; this sharp, universal cemented‑carbide formulation is chosen to reduce built‑up edge in the recommended applications.

Can this insert be used for finishing as well as general turning?
Yes; the sharp TH10 grade and 0.8 mm corner radius suit finishing and light to medium turning passes, delivering improved surface quality when appropriate cutting parameters are applied.

How does chip control work with this geometry?
The integrated double‑sided chipbreaker is engineered to form short, manageable chips; combined with the square geometry and correct feeds, this improves process stability and eases chip disposal.
