VNMG 120404 GT9530 – Indexable turning insert (coated cermet, TSF chipbreaker) by Tungaloy

VNMG120404E-TSF GT9530 is an ISO-standard rhombic indexable insert for turning applications, designed for finishing to light general-purpose cuts in steel where surface quality and longer life are required

• Coated cermet grade GT9530
• Optimised TSF chipbreaker for steel
• Rhombic VNMG, 12 mm inscribed circle
• 0.4 mm corner radius for fine finish

Consistent finishing and prolonged tool life for steel turning

The insert’s coated cermet composition (grade GT9530) is engineered for stable wear behaviour during finishing and light general-purpose turning of steel. A cermet combines ceramic hardness with metallic toughness, which helps to maintain a sharp cutting edge and deliver a superior surface finish compared with conventional carbide grades under stable machining conditions. The result is fewer in-process reworks and a more predictable production rhythm, supporting efficient batch runs and higher first-pass quality.

Reliable chip control and thermal stability under steady feed conditions

Equipped with the TSF chipbreaker, the geometry promotes controlled chip formation and evacuation in typical finishing feeds. The chipbreaker reduces the risk of entangling long chips and supports steady cutting forces, which in turn helps to protect the insert edge and the workpiece surface. Thermal resistance of the coated cermet also contributes to edge stability at moderate cutting speeds, so surface integrity and dimensional accuracy remain consistent throughout the tool life.

Geometry and ISO conformity simplify tool selection and clamping

The rhombic VNMG form with a 35° approach angle and a 0.4 mm corner radius is a common geometry that fits a broad range of ISO-compatible holders. ISO conformity of form, clearance angle, size and thickness ensures that the insert can be matched to holders by specification rather than trial, reducing setup time. The central cylindrical hole and standard thickness facilitate secure fastening and repeatable positioning, which is crucial for serial production and quick insert changes.

Integration into production workflows and material suitability

This insert is intended primarily for turning of steel under stable, finish-oriented conditions; the coated cermet grade is optimised for wear resistance and surface quality rather than heavy interrupted cuts. Selection of feeds, speeds and holder rigidity should reflect the insert’s strengths: light to moderate depths of cut with stable machine and work-holding yield the best combination of surface finish and tool life. For uncertain cases, match the TSF chipbreaker and GT9530 grade to the workpiece material and process stability for optimal results.
