CNMG 120408 TH10 indexable turning insert for turning — Tungaloy

A CNMG 120408 TH10 ISO-indexed rhombic insert designed for external and internal turning, optimised for low cutting forces and a clean finish in non-ferrous applications

• ISO CNMG geometry, 80° rhombic
• Uncoated tungsten carbide, TH10 grade
• Double-sided insert for economical use
• Cylindrical hole for secure clamping

Precise cutting with lower forces for cleaner finishes

The combination of an uncoated tungsten carbide substrate and the TH10 grade is engineered to reduce cutting forces while maintaining a sharp, stable cutting edge. This makes the insert particularly suitable for machining softer, non-ferrous materials where low force and a clean surface are priorities. The rhombic ISO CNMG geometry with an 80° lead angle provides a versatile cutting orientation that supports both roughing and finishing passes, while the double-sided design effectively doubles the available cutting edges, reducing tool change frequency and cost per edge. The built-in chipbreaker configuration supports controlled chip formation; selecting the correct chipbreaker for the material and operation improves evacuation and surface consistency.

Economical tooling and straightforward set-up in ISO systems

Interchangeability and compatibility are central to efficient production. The insert’s dimensions — 4.76 mm thickness and 12 mm inscribed size — together with the cylindrical hole and standard ISO geometry ensure reliable seating in compatible holders. The 0° relief angle and a 0.8 mm corner radius are suitable for commonly required surface finishes while keeping cutting loads moderate. As an indexable insert, it integrates into established tool systems with a matching holder, shim and clamp set, enabling quick replacement and minimal set-up downtime. The reversible nature and consistent edge preparation result in predictable performance and an improved cost-to-output ratio.

Clear selection criteria and support for production environments

Choosing the correct grade and chipbreaker is decisive for stable productivity. For external and internal turning operations, the TH10 grade is a sharp universal solution where an uncoated edge supports low cutting force and good surface quality. Compatibility with holders is determined by form, freedom angle, tolerance class, fastening method, size and thickness — factors that govern clamping stability and machining accuracy. For application planning, note that the insert is intended for turning and should be matched to the workpiece material and machine stability. Specialist advice is available for process optimisation and narrower tolerances to ensure reproducible results.

FAQ

Which materials is this insert best suited for? The CNMG 120408 TH10 Tungaloy indexable insert is optimised for non-ferrous materials and applications where a sharp uncoated cutting edge yields low cutting forces and a clean surface finish.

Is the insert reversible and how many edges are available per insert? Yes — the insert is double-sided, offering two usable edges per side for a total of four cutting positions before replacement, which improves economy in production.

How does the insert clamp to the holder? Clamping is achieved via the cylindrical hole and standard ISO CNMG seating; compatibility depends on matching form, relief angle, tolerance class, fastening method, size and thickness.

Can this insert be used for internal turning? Yes, the geometry and chipbreaker make it suitable for both external and internal turning operations when matched with appropriate holders and stability.

What edge radius and thickness should be expected for surface finish control? The insert has a corner radius of 0.8 mm and a thickness of 4.76 mm; these dimensions support controlled cutting forces and consistent surface quality when programmed accordingly.

Where can one get recommendations for holder selection and process parameters? Metav Werkzeuge can provide application advice and recommend compatible holders and cutting data for the CNMG 120408 TH10 indexable insert (SKU 6802077-Tungaloy).
