RCMT 0803M0 NS9530 – ISO turning insert for finishing, Tungaloy

The RCMT0803M0 NS9530 is an ISO-standard indexable turning insert designed for finishing operations on Stahl, offering a sharp cutting edge and a chipbuster suited to continuous cuts.

• ISO form RCMT 0803M0, round insert
• Uncoated cermet grade NS9530, finishing use
• Sharp cutting edge with low cutting forces
• Cylindrical hole with single-side countersink

Superior finishing quality with minimal cutting force

The uncoated cermet grade NS9530 is formulated for precise finishing on Stahl, delivering a sharp cutting edge that reduces built-up edge and lowers cutting forces during continuous cuts. This characteristic leads to a measurable improvement in surface integrity and can reduce the need for secondary finishing operations. With a small corner radius and an insert thickness of 3.18 mm, the geometry supports fine depth-of-cut control and consistent contact with the workpiece, producing reliable dimensional conformity and repeatable surface results.

Assured compatibility and stable clamping for repeatable results

As an ISO-standard round insert, the component is compatible with holders that match the insert form, clearance, tolerance class, fixing and thickness. The system build—insert, appropriate external holder or boring bar, shim/clamp set and replacement screws—ensures a secure mechanical interface and stable cutting conditions. The 7° clearance helps to prevent rubbing and to maintain a sharp cutting action, while the cylindrical hole with a single-side countersink (40°–60°) permits robust, repeatable clamping and quick indexability, supporting shorter cycle times and predictable tool behaviour.

Process efficiency and recommended use cases

Designed specifically for finishing, this insert excels with small feeds and continuous cutting strategies; the single-sided chipbreaker complements the sharp edge by controlling chip form for stable evacuation. The combination of the NS9530 substrate and the insert geometry supports long runs with consistent surface quality, which translates into lower overall machining costs and higher throughput. For best results, pair the insert with a rigid holder and select feeds and speeds appropriate for finishing Stahl; the result is improved productivity and reduced rework.

FAQ

What is the intended application for this insert?
The RCMT0803M0 NS9530 insert is intended for turning operations, specifically finishing applications on Stahl where a sharp cutting edge and low cutting forces are required.

Is the insert compatible with ISO tool holders?
Yes, the insert follows ISO form RCMT 0803M0; compatibility depends on matching holder form, clearance, tolerance class, fixing, size and thickness.

What is the cutting material and grade?
The grade is NS9530, an uncoated cermet designed for finishing Stahl with good surface results and low cutting forces.

How does the clamping hole support tool reliability?
The cylindrical hole with a single-side countersink (40°–60°) provides secure and repeatable clamping, improving stability and indexability during turning.

Can this insert be used for interrupted cuts?
As a finishing cermet with a sharp edge and single-sided chipbreaker, the insert is optimised for continuous cuts and small depths of cut; interrupted cutting may reduce edge life and is not the primary use case.
