CNMG 120408 AH120 Turning Insert by Tungaloy — ISO rhombic indexable insert for turning, PVD-coated carbide, 80°

A CNMG120408 AH120 Tungaloy turning insert designed as an ISO-standard rhombic indexable insert for general turning operations, compatible with holders matched by form, clearance, tolerance class, clamping and size.

• CNMG120408 ISO rhombic insert
• PVD-coated carbide AH120 grade
• Double-sided chipbreaker, with hole
• 0.8 mm corner radius for sharp edge

High cutting reliability and wear resistance for consistent production

The PVD-coated carbide composition of this insert provides enhanced wear resistance and a reliably sharp cutting edge, while the AH120 grade is formulated for a balance of fracture resistance and edge retention. The 80° geometry increases cutting-edge robustness, making the insert well suited to shoulder cuts and more demanding external turning where stability is essential. Integrated double-sided chipbreakers improve chip formation and evacuation, reducing vibration and contributing directly to cycle-time stability and surface quality.

Simple integration into ISO tooling systems to reduce setup time

Supplied as an ISO-format component, the insert follows standard dimensions so compatibility checks focus on form, free clearance, tolerance class, clamping method, size and thickness. This clarity in specification simplifies tool-room selection: matching an appropriate external holder or boring bar and ensuring the correct backing/ clamping set and replacement screws completes the system. The predictable interface reduces setup iterations and minimises machine downtime, supporting higher first-pass yields and more efficient changeovers.

Long tool life and application fit that cuts operating costs

With a 0.8 mm corner radius and a PVD-protected cutting surface, the indexable insert balances a sharp edge for fine finishes with toughness to resist edge chipping under interrupted cuts. The double-sided design extends usable life before indexing, offering economical performance in batch and series production. Intended for general turning, both external and internal, this insert is particularly appropriate where a sharp cutting edge and process security are required, enabling repeatable surface quality and reduced rework.

FAQ

What materials is this insert intended for? The CNMG120408 AH120 Tungaloy indexable insert (SKU 6811624-Tungaloy) is engineered as a wear- and breakage-resistant grade for turning applications where a sharp cutting edge and process security are required.

Is the insert reversible and how many cutting edges are available? The indexable insert is double-sided with two usable cutting edges per side, allowing multiple indexing positions before replacement and extending productive tool life.

Which holder features must be matched to ensure compatibility? Compatibility is determined by the holder's form, free clearance (ferrule/relief angle), tolerance class, clamping style, size and thickness; matching these ensures secure seating and correct cutting geometry.

Does the AH120 grade include a coating, and what benefit does it bring? Yes, the AH120 grade is PVD-coated carbide; the coating improves wear resistance and maintains edge integrity under cyclic and continuous turning operations, enhancing process stability.

Can this insert be used for both external and internal turning? The insert's rhombic ISO design and 80° geometry make it suitable for both external and internal turning tasks when paired with the appropriate external holder or boring bar.
