CNGG 120404 NS9530 rhombic turning insert for finishing applications — Tungaloy

The CNGG120404 NS9530 is an ISO‑designated rhombic turning insert intended for finishing steel, offering a sharp cutting edge and suitability for continuous cuts in light‑duty turning.

• ISO‑compatible rhombic insert
• Uncoated cermet NS9530 finishing grade
• 0.4 mm corner radius for fine finishing
• Double‑sided chipbreaker, with cylindrical hole

Achieve consistently superior surface finish with low cutting forces

The combination of an uncoated cermet matrix and the NS9530 designation is optimised for finishing steel, delivering a high surface finish while keeping cutting forces low. The ground, sharp edge reduces built‑up edge formation during continuous cuts and small depths of cut, so cycle times remain stable and rework is minimised. The built form supports operations where surface integrity and dimensional accuracy are priorities, translating insert properties into measurable process advantages.

Reliable clamping and straightforward ISO compatibility

Manufactured to an ISO geometry, the rhombic form ensures predictable seat and datum engagement with compatible holders. The geometry features a 4.76 mm thickness, an inscribed circle of 12 mm, and a 0° relief, which together determine stack‑up, rigidity and the accessible cutting depth. The insert is supplied with a cylindrical hole for positive locating and secure fastening; these measurable attributes simplify tool selection and reduce setup variability on production lines.

Process recommendations for stable, economical turning

The double‑sided chipbreaker design suits continuous turning and assists chip control when paired with appropriate coolant and a rigid toolholder. Use this insert in fine finishing passes with small feed rates to exploit its 0.4 mm radius for improved edge strength and surface quality. For consistent results, match the insert grade and chipbreaker to the workpiece and machining stability — choosing a stable holder and correct clamping torque reduces vibration and extends tool life, contributing to overall process economy.

FAQ

What materials is this insert best suited for?
The CNGG120404 NS9530 insert is a finishing grade optimised for steel; its uncoated cermet chemistry and sharp cutting edge favour continuous turning operations on steel workpieces.

How is the insert clamped and aligned?
Alignment and clamping rely on the ISO rhombic datum and the cylindrical hole; the CNGG120404 designation ensures compatibility with holders designed for that ISO geometry and 12 mm inscribed circle.

Can this insert be used for roughing?
This grade and geometry are intended for finishing passes; the NS9530 finishing grade and 0.4 mm corner radius are not optimised for heavy roughing or interrupted cuts.
