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.

The clear benefit is fewer interruptions and a predictable part quality that supports efficient production planning. Broad material suitability and reduced cutting effort The uncoated carbide grade TH10 is a universal, sharp grade intended for non-ferrous workpieces and applications that benefit from low cutting forces and clean surfaces. Compared with tougher, coated grades, this sort of cutting edge helps to avoid built-up edge when machining softer metals, improving surface integrity and reducing burr formation. For applications where minimal cutting resistance and good finish are priorities, the grade offers an economical alternative while maintaining acceptable tool life under appropriate cutting conditions. Robust geometry and secure clamping for repeatable results The insert features a rhombic geometry with an 80° approach angle and a 0.8 mm corner radius, providing a balance between edge strength and finishing capability. The insert thickness (4.76 mm) and cylindrical hole facilitate a secure clamp in ISO-compatible holders; the compatibility is determined by holder form, clearance angle, tolerance class, clamping method, size and thickness. Using the correct combination of holder and fastening hardware ensures repeatable clamping, accurate positioning and consistent cutting behaviour across production batches. Practical integration and selection advice The ISO designation and dimensional data make the insert straightforward to specify for existing tool systems: size 12 mm and the standard CNMG outline permit direct comparison with alternative inserts from other manufacturers. Selecting the appropriate chipbreaker and grade for the specific workpiece material and machining stability is the primary factor in achieving the desired balance between surface finish and productivity. For setups with constrained rigidity, the sharp TH10 grade yields lower cutting forces; where higher robustness is required, consider a different grade or edge preparation.

Why indexable inserts are indispensable in modern machining
Indexable inserts, also known as cutting inserts or indexable cutting inserts, are standardised, replaceable cutting elements that mount on tool holders such as turning bits, milling cutters or drills. Made from wear-resistant materials like carbide, cermet, ceramic or other superhard grades, they carry the actual cutting edge and allow a worn corner to be rotated or flipped instead of replacing or regrinding the entire tool body.
How these inserts work and when to choose them
In everyday workshop and production settings, indexable inserts perform the direct material removal on the workpiece. Standard inserts for tool systems without internal coolant typically feature closed faces or a single central fixing hole, with heat evacuation handled by external machine nozzles. Inserts designed for systems with internal coolant are engineered to support coolant flow: they include calculated chipbreaker geometries that guide an internal coolant jet under the chip or, in specialised designs, contain sintered microchannels to direct coolant right to the cutting edge. Such coolant-compatible inserts are essential for machining heat-resistant alloys, heavy cutting operations and deep internal machining, where thermal load and chip control are critical.
Tangible benefits for production and workshop efficiency
Choosing the right indexable inserts delivers measurable operational advantages:
- Reduced downtime: faster changeover because a worn insert is simply indexed rather than the whole tool being replaced.
- Extended cutting-edge life: targeted coolant application and optimised chipbreaker design lower thermal stress and improve tool life.
- Consistent part quality: predictable cutting-edge geometry from standardised inserts maintains tolerances across batches.
- Versatility: availability in carbide, cermet, ceramic and superhard grades permits selection according to workpiece material and cutting conditions.
- Lower tooling costs over time: fewer full-tool replacements and less regrinding required.

FAQ
What materials are indexable inserts available in?
Indexable inserts are available in wear-resistant grades such as carbide, cermet, ceramic and other superhard materials, selected according to the workpiece material and cutting conditions.
When should I choose inserts with internal coolant support?
Choose inserts designed for internal coolant when machining heat-resistant alloys, performing heavy cuts or working in deep internal features, because the coolant reduces thermal load at the cutting edge and actively improves chip breakage.
How do chipbreaker geometries affect performance?
Chipbreaker geometries on indexable inserts guide the chip flow and, when matched to an internal coolant jet, direct the coolant under the chip to control temperature and facilitate reliable chip formation, which extends edge life and stabilises machining.
Can standard inserts be used with external coolant only?
Yes; standard inserts for tool systems without internal coolant typically have closed faces or a central fixing hole and rely on external machine nozzles for heat evacuation, which is sufficient for many routine, accessible cuts.
