CNGG 120404 TH10 — Indexable turning insert for turning by Tungaloy

CNGG120404 TH10 Tungaloy turning insert is an ISO-indexed, rhombic insert engineered for external and internal turning where low cutting forces and clean surfaces are required

• ISO-indexed CNGG geometry for broad compatibility
• Uncoated carbide TH10 for low cutting forces
• Rhombic shape with 80° approach angle
• 0.4 mm nose radius for fine surface finish
• Double-sided chipbreaker with cylindrical hole

Consistent cutting with a sharp, universal grade

The combination of an ISO-standard geometry and the TH10 uncoated carbide grade provides predictable cutting behaviour across a wide range of non-ferrous and delicate applications. The sharp edge reduces required cutting force, which helps to limit deflection on less rigid setups and supports a clean surface finish. Uncoated grades are especially suitable where adhesion or built-up edge risk must be minimised and where a defined cutting edge is preferred over coated alternatives.

Geometry that supports precision and repeatability

A 0.4 mm nose radius paired with the 80° approach angle and the rhombic plate form delivers a balance between profile strength and fine finishing capability. The specified nose radius directly influences surface roughness and allowable feed rates: a smaller radius helps achieve tighter finishes with lower feed, while the 80° geometry gives a reliable cutting direction for both facing and longitudinal turning. These features contribute to repeatable results when the rest of the machining system is appropriately selected.

Secure mounting and system compatibility explained

Compatibility with the toolholder is governed by the insert’s form, relief angle, tolerance class, fastening method, size and thickness; the presence of a cylindrical hole supports positive location and firm clamping. With a 4.76 mm thickness, the insert provides sufficient stability in standard external holders and boring bars when clamped correctly. The double-sided chipbreaker extends usable life by allowing indexation of the insert, helping maintain process uptime.

Application suitability and chip control guidance

The grade is intended as a sharp, universal solution for non-ferrous materials and for operations that benefit from a clean, uncoated cutting edge. The double-sided chipbreaker is designed to manage chips on a variety of workpiece materials provided the appropriate chipbreaker variant and cutting parameters are selected. For best results, choose a chipbreaker and grade that match the part material, machining strategy and machine-tool rigidity.

Practical system approach for production stability

An indexable insert performs best as part of a system: the insert, a matched external holder or boring bar, a support shim or clamp set and the correct fastening screw together determine the operational reliability. Ensuring the holder accepts the CNGG form and the specified clearance is essential; incorrect holder selection is a common source of vibration or poor surface finish. The ISO-series design simplifies holder selection by adhering to established geometric standards.

Setup tips to reduce trial-and-error

Select the TH10 grade and the double-sided chipbreaker when low cutting forces and clean finishes are priorities; for heavier interrupted cuts or harder materials, consider a different grade or a coated alternative. Check the holder’s tolerance class and ensure the clamping screw and underlay match the insert thickness. For further matching of holder geometry and process parameters, technical consultation is recommended to avoid unnecessary tool wear or poor surface results.

FAQ

Is this insert suitable for both external and internal turning?
Yes. The CNGG120404 TH10 insert is designed for both external and internal turning when used with a compatible external holder or boring bar and the appropriate clamping set.

Which materials are best machined with the TH10 grade?
The TH10 uncoated carbide grade is optimised for non-ferrous materials and operations requiring low cutting forces and clean surfaces; it performs well where a sharp, uncoated edge is advantageous.

How does the 0.4 mm nose radius affect surface finish?
A 0.4 mm nose radius helps achieve finer surface finishes at lower feeds and reduces the risk of workpiece indentation compared with larger radii; selection should match the intended feed rates and part tolerance.

What determines whether the insert fits a specific holder?
Fit is determined by the insert form, relief angle, tolerance class, fastening method, size and thickness; ensure the holder accepts the CNGG geometry and 4.76 mm plate thickness.

Can the insert be indexed to use both sides?
Yes. The insert is double-sided with a chipbreaker design that allows indexation to the second cutting edge, extending tool life and minimising downtime.
