CNMG120404 NS9530 CNMG 120404 turning insert for finishing — Tungaloy

CNMG120404 NS9530 is an ISO‑standard indexable turning insert engineered for fine finishing of steel in continuous turning operations

• ISO CNMG 120404 geometry for interchangeability
• Uncoated cermet NS9530 for finishing of steel
• 0.4 mm nose radius for fine surface quality
• Double‑sided chipbreaker with cylindrical hole

Achieve high‑quality finishes with a finishing‑grade cermet

The CNMG120404 NS9530 insert combines an uncoated cermet cutting grade with a sharp cutting edge, designed specifically to reduce cutting forces and improve surface integrity when turning steel. Cermet materials merge ceramic hardness with metal toughness, which in practice means lower built‑up edge, enhanced wear resistance in continuous cutting and consistently superior part surfaces. The small 0.4 mm nose radius is ideal for producing fine finishes and holding tight form tolerances without excessive cutting loads, while the 0° rake supports stable chip formation during light finishing cuts.

Reliable interchangeability and secure clamping in ISO holders

Built to the ISO CNMG120404 form, this insert ensures clear compatibility with matching external holders and boring bars; compatibility depends on form, relief angle, tolerance class, attachment method, size and thickness. The rhombic plate form, 12 mm size and 4.76 mm thickness are industry standard dimensions that simplify tool procurement and tooling set‑up. The insert is supplied with a cylindrical hole, allowing secure fastening with standard screws and bases; this reduces set‑up time and ensures repeatable clamping for batch production.

Application guidance and process benefits for turning steel

As a finishing grade, the NS9530 composition excels in continuous cuts and small depths of cut, where the priority is surface quality and low cutting forces rather than heavy material removal. The double‑sided chipbreaker supports consistent chip control in light turning operations and enables economical use of the indexable insert by allowing both sides to be used. For users seeking process stability and predictable component finish, this solution offers a practical balance between edge sharpness and wear life, helping to shorten non‑productive times and increase yield on finished parts.

FAQ

What types of turning operations suit this insert best?
The CNMG120404 NS9530 insert is optimised for finishing passes in external and internal turning, particularly where a fine surface finish on steel is required.

Is the insert compatible with standard CNMG holders?
Yes, the ISO CNMG120404 geometry ensures compatibility with standard CNMG external holders and boring bars, provided matching size, thickness and clamp arrangement.

Can the NS9530 grade be used for interrupted cuts?
NS9530 is a finishing‑orientated cermet best used for continuous cuts and small depths of cut; for heavily interrupted machining a tougher grade is usually advisable.

How many usable edges does the insert offer?
The rhombic CNMG form with a double‑sided chipbreaker provides multiple indexable edges per insert, enabling economical edge changes and extended tool utilisation.
