CNGG 120402 TH10 Turning insert (ISO 120402) — Tungaloy

The CNGG120402 TH10 insert is an ISO-standard rhomboid indexable insert for turning, designed for economical, low-force machining of non-ferrous materials and other applications requiring a clean surface finish.

• ISO-standard compatibility
• Sharp uncoated carbide grade TH10
• Double-sided chipbreaker for economy
• Cylindrical hole for secure clamping

Reliable fit and straightforward integration for workshop use

The ISO-standard design of this rhomboid insert ensures predictable compatibility with matching holders when form, relief angle, tolerance class, clamping method, size and thickness are observed. The cylindrical hole and standardised geometry simplify fixture selection and replacement, reducing set-up time and streamlining inventory management. For production environments where repeatability matters, the standardised format supports consistent seating and repeatable orientation in both external and internal turning operations.

Low cutting forces and improved surface quality with TH10

The uncoated TH10 grade is a sharp, universal carbide developed for non-ferrous materials and processes that benefit from a clean cutting edge. Thanks to the sharp cutting edge and the small 0.2 mm corner radius, the insert promotes reduced cutting forces and finer finishes, especially on softer alloys and non-ferrous workpieces. The result is efficient material removal with minimal burr formation and less need for subsequent finishing, supporting a smoother production flow.

Economic use and extended service life through reversible design

Featuring a double-sided chipbreaker, the insert offers two usable cutting edges per side, effectively multiplying usable edges and lowering tooling costs per part. The uncoated carbide substrate delivers reliable edge sharpness where coatings would not be advantageous, and the rhomboid form factor allows economical indexing. Combined with the 4.76 mm thickness and robust seat contact provided by the 80° cutting angle, the geometry supports stable cutting for general turning tasks while keeping tool change frequency low.

Practical handling and selection guidance for best results

The insert has a 0° relief angle, which must be matched to an appropriate holder geometry to secure the intended clearance and rake behaviour. Choosing the correct chipbreaker variant and the TH10 grade helps to optimise chip control and surface integrity for the intended material. For most standard turning applications, select a compatible ISO holder that accommodates the rhomboid shape and the cylindrical mounting hole to ensure secure clamping and repeatable performance.

FAQ

Which materials are best processed with this insert?

The TH10 uncoated carbide grade is intended primarily for non-ferrous materials and operations where a sharp edge supports low cutting forces and a clean surface finish; the insert is suitable for a broad range of softer alloys.

Is the insert reversible and how many cutting edges are usable?

Yes, the rhomboid geometry with a double-sided chipbreaker allows multiple indexing positions; this design extends usable life by providing several effective cutting edges before replacement is needed.

How does the 0° relief angle affect holder choice?

A 0° relief angle requires selection of a holder designed to provide the required clearance and to match rake and seat geometry; correct holder matching ensures stable cutting and repeatable seating.

Does the insert have a coating?

This product is supplied as uncoated carbide in the TH10 grade, chosen to maintain a sharp cutting edge where coatings are not beneficial for the process.

Which chipbreaker should be selected for optimal performance?

The supplied double-sided chipbreaker provides good general-purpose chip control for non-ferrous turning; choose the exact chipbreaker and grade based on material, feed and stability to balance chip shape and surface finish.
