CNMG120408 TH10 Tungaloy indexable insert for turning, uncoated carbide, 80° rhombic

The CNMG120408 TH10 is an ISO‑standard turning insert designed for external and internal turning where low cutting forces and fine surface finish are required.

• ISO‑standard CNMG geometry, 80° rhombic
• Sharp uncoated carbide TH10 for low cutting forces
• Double-sided chipbreaker for reliable chip control
• Cylindrical hole, compatible with standard holders

Consistent fit and easy integration into ISO turning systems

The CNMG form follows established ISO dimensions, ensuring reliable seating and repeatable clamping in compatible holders and boring bars. The 80° rhombic geometry offers a stable cutting angle for general turning tasks, while the cylindrical hole and standard fixing features support straightforward replacement and indexing. Thanks to the ISO conformity, the insert integrates with common shims, clamps and screws in modular tool systems, reducing setup time and helping maintain predictable process parameters.

Low cutting forces and a finish-focused grade for non‑ferrous work

The uncoated TH10 grade is a sharp, universal carbide developed for applications on non‑ferrous materials and situations that demand low cutting forces. An uncoated cutting edge reduces built-up edge tendency when machining softer alloys and contributes to a clean surface without additional surface‑treatment layers that can alter edge geometry. The combination of a sharp grade and the double‑sided chipbreaker supports smooth chip formation and evacuation, which benefits surface integrity and reduces the risk of material transfer to the cutting edge.

Practical handling, edge geometry and durability in daily use

With a 0.8 mm corner radius and a plate thickness of 4.76 mm, this indexable insert balances strength and form: the corner radius allows modest finishing cuts while the plate thickness contributes to stability under moderate cutting forces. The rhombic shape offers two usable cutting edges per side where applicable, and the insert’s design supports quick indexing, cutting tool changeover and reduced machine downtime. These characteristics help to maintain productivity in batch production and mixed‑material environments.

Recommended applications and selection guidance

Best suited for turning operations on non‑ferrous alloys and components requiring a tidy surface finish, the insert performs well where low cutting loads are advantageous. Select the TH10 uncoated grade and the double‑sided chipbreaker when machining aluminium, brass or similar alloys; adjust feed and speed based on material rigidity and machine stability. For heavier interrupted cuts or hardened steel applications, a different coated grade should be considered to match wear resistance and edge retention requirements.

FAQ

What materials is this insert best suited for?
The CNMG120408 TH10 insert is aimed primarily at non‑ferrous materials such as aluminium and brass; the uncoated TH10 grade supports low cutting forces and clean surfaces when turning these alloys.

How does the double‑sided chipbreaker affect machining?
A double‑sided chipbreaker improves chip control on both cutting edges, helping to form manageable chips and supporting surface quality during continuous turning operations with the Tungaloy indexable insert.

What dimensions are critical for holder compatibility?
Compatibility depends on the ISO CNMG geometry, the 12 mm inscribed circle, the 4.76 mm plate thickness and the 80° cutting angle; matching these values with the toolholder ensures correct seating and clamping.

Can the insert be indexed to use multiple cutting edges?
Yes; the rhombic CNMG form and the plate design allow indexing to present fresh cutting edges, reducing tool change frequency and improving overall productivity.
