VNMG120402E-TSF AT9530 indexable turning insert for turning applications — Tungaloy

VNMG120402E-TSF AT9530 is an ISO rhombic indexable insert designed for finishing and light turning of steel, prioritising surface quality and uniform wear

• Coated cermet grade AT9530
• TSF chipbreaker for finishing cuts
• 0.2 mm corner radius for fine surfaces
• ISO VNMG form with cylindrical hole

Achieve superior surface finish with a specialised cermet grade

The insert is engineered for precision finishing: the coated cermet AT9530 was developed to provide a balance between hardness and toughness, yielding consistent wear and a high-quality surface on machined steel. For light and finishing passes the TSF chipbreaker controls chip form to reduce vibration and avoid surface damage, which leads to fewer downstream operations and more predictable production cycles. The rhombic geometry and 0.2 mm corner radius support fine edge behaviour, enabling tight tolerances and reliable repeatability in batch production.

Improve process stability and productivity through predictable tool life

A clear advantage of this grade and geometry is stable wear progression, which simplifies tool-change planning and reduces scrap. The coated cermet composition resists abrasive wear typical in finishing, so component quality remains constant over the life of the insert. With reduced tool deviations, cycle times become repeatable and setup frequency is lowered, supporting cost-efficient machining and improved overall equipment effectiveness (OEE). These rational gains directly benefit production planning and reduce unplanned downtime.

Easy integration into ISO tool systems and adaptable holder compatibility

Designed to the ISO standard VNMG form, the insert fits common external holders and boring bars when the holder matches in form, clearance angle, tolerance class, fastening method, size and thickness. The cylindrical hole and standard thickness of 4.76 mm facilitate safe clamping and interchangeability across existing tool systems, allowing a straightforward retrofit into established turning processes. Compatibility reduces inventory complexity and helps sustain machining performance without extensive tooling changes.

Practical guidance for machining steel with controlled chip formation

For finishing operations on steel the recommended approach is light depth of cut and moderate feed, taking advantage of the TSF chip control to maintain short, curl‑free chips and a stable cutting zone. The insert’s construction supports high surface integrity while maintaining economical cutting conditions. When selecting a grade and chipbreaker, consider the workpiece clamping and machine rigidity first; the insert then contributes to reproducible surface finish and uniform edge wear, easing inspection and downstream handling.
