CNMA 120408 TH10 Turning Insert (ISO CNMA120408) – Tungaloy

CNMA120408 TH10 is an ISO-standard rhombic turning insert for external and internal turning, optimised for non-ferrous materials where a sharp, uncoated edge reduces cutting forces and improves surface finish.

• ISO CNMA120408 geometry for holder compatibility
• Sharp uncoated carbide grade TH10 for low cutting forces
• 0.8 mm corner radius for fine surface quality
• Cylindrical-hole rhombic plate, 80° cutting angle

Reliable low-force cutting for non-ferrous turning

The TH10 grade is an uncoated carbide designed as a sharp universal grade for machining non-ferrous materials, giving notably low cutting forces and a clean surface finish. Where chip formation is predictable and cutting forces must be minimised, such as finishing aluminium components or machining softer alloys, this edge preparation supports consistent results and reduced power draw. The combination of a sharp edge and the plate’s geometry helps to lower burr formation and facilitates downstream processes.

ISO geometry and secure clamping for stable machining

The insert follows the ISO-standard CNMA120408 geometry and the rhombic plate form, with a cylindrical hole for positive location in many common clamping systems. The 0.8 mm radius and 80° approach angle ensure predictable engagement with the workpiece; compatibility to a holder is governed by form, clearance angle, tolerance class, fastening method, size and thickness. Designed as part of a system—indexable insert, matching external holder or boring bar, shim/clamp set and replacement screws—this plate integrates into established toolholders for predictable repeatability.

Practical advantages that support productive turning

For both external and internal turning operations, the plate’s plain cutting edge (no chipbreaker fitted) simplifies edge condition control and can improve finishing passes. Selecting the correct chipbreaker and grade for the workpiece stability and cutting conditions remains essential; when high stability is available, the TH10 grade performs efficiently and extends effective cutting windows. The insert’s nominal thickness and standard form make tooling planning straightforward, reducing downtime for changeovers and enabling reliable cycle times in batch production.

FAQ

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

Can this insert be used for both external and internal turning?
Yes, the indexable insert is suitable for both external and internal turning when paired with an appropriate external holder or boring bar and the correct clamping kit.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm radius balances edge strength and surface finish: it supports fine finishing while maintaining sufficient edge stability for typical finishing feeds.

Is a chipbreaker included on this insert?
This plate is supplied without a chipbreaker; chip control depends on grade selection, cutting data and the chosen holder geometry.

How is holder compatibility ensured for this ISO insert?
Compatibility is determined by the plate form, relief angle, tolerance class, fastening method, size and thickness; use holders specified for ISO CNMA form to ensure correct seating and security.
