VNMG 120408 AT9530 turning insert by Tungaloy — rhombic VNMG form, TSF chipbreaker

A VNMG120408E-TSF AT9530 indexable turning insert designed for fine and light finishing operations on steel, optimised for consistent wear and improved surface integrity

• Coated cermet grade AT9530
• Rhombic VNMG form with 0° clearance
• 0.8 mm corner radius for fine surface finish
• Cylindrical hole for secure clamping

Consistent finishing with a cermet grade built for surface quality

The AT9530 coating combines a cermet top layer with a robust substrate to balance hardness and toughness. This results in improved surface finish and uniform wear resistance during fine and light machining of steel. The material selection reduces built-up edge tendencies typical of finishing cuts and helps maintain a predictable tool-life profile, supporting higher process stability and fewer regrinds.

ISO compatibility and secure mounting for reliable turning cycles

Designed as an ISO-standard turning insert, compatibility with a support or holder is governed by form, relief angle, tolerance class, fastening method, size and thickness. The cylindrical hole and standard VNMG clamping interface provide secure seating and repeatable positioning, while the 4.76 mm plate thickness contributes to axial stiffness in the holder assembly. These characteristics minimise vibration and support consistent dimensional control in production.

Geometry tuned for fine and light machining with controlled chips

The rhombic plate geometry combined with a 0° relief angle and a 0.8 mm corner radius delivers a balance of cutting-edge strength and surface integrity, particularly on finishing passes. The TSF chipbreaker is tailored for fine feeds and shallow depths of cut, producing short, manageable chips and supporting automatic chip evacuation. The result is reduced rework, improved part surface quality and predictable tool performance.

Practical application and procurement guidance for production environments

Suitable for both external and internal turning, these indexable inserts fit into a system comprising an ISO turning insert, a suitable external holder or boring bar, and standard clamping accessories. For inventory control and ordering, note the manufacturer item number 6773726 and the manufacturer SKU TUN6773726; these identifiers assist rapid reordering and traceability. For matching holders, process parameters or material-specific advice, Metav Werkzeuge offers application support and selection guidance to integrate the insert efficiently into machining setups.

FAQ

Is this insert suitable for finishing steel?
Yes. The VNMG120408E-TSF AT9530 insert from Tungaloy is specified for fine and light finishing of steel, where surface quality and even wear are priorities.

Which holders are compatible with this insert?
Compatibility depends on insert form, relief angle, tolerance class, fastening type, size and thickness; select a VNMG-compatible external holder or boring bar matched to the VNMG120408E-TSF geometry.

What advantages does the TSF chipbreaker provide?
The TSF chipbreaker is optimised for shallow depths and fine feeds, enabling consistent chip segmentation and stable cutting when using the AT9530 grade in finishing operations.

Can this insert be used for internal turning as well as external turning?
Yes. The insert is suitable for both external and internal turning, provided the holder geometry and reach are appropriate for the operation and the required clearance is maintained.

How does the 0.8 mm corner radius affect the component surface?
A 0.8 mm corner radius delivers a compromise between edge strength and a fine surface finish, reducing the risk of edge chipping while producing improved surface integrity on finishing passes.

What details are helpful when reordering replacements?
Provide the label VNMG120408E-TSF AT9530, the manufacturer article number 6773726 and the manufacturer SKU TUN6773726 to ensure identical replacement parts.
