CPMT 090302 NS9530 Tungaloy turning indexable insert — rhombic 09, 0.2 mm corner radius, 11° clearance

CPMT090302 NS9530 Tungaloy‑Wendeplatte is an ISO‑standard indexable insert for turning, designed for finishing steel components with low cutting forces and a sharp cutting edge

• ISO‑standard rhombic insert
• Uncoated cermet NS9530 for finishing
• Sharp cutting edge for low cutting forces
• Cylindrical hole with single‑side countersink

Achieve superior finishes on turned steel components

The uncoated cermet grade NS9530 is formulated as a finishing class for steel, offering a sharp cutting edge that reduces plastic deformation at the cutting zone and promotes excellent surface finish. With a small, defined 0.2 mm corner radius and a plate thickness of 3.18 mm, this insert limits burr formation and supports consistent part tolerances during continuous cuts and small depth of cut operations. The material behaviour of cermet combines ceramic hardness with metallic toughness, which means improved edge stability when producing fine surfaces on shafts, housings and other turned parts.

Reliable clamping and geometry for predictable process stability

The rhombic 09 geometry and ISO form ensure straightforward compatibility with a wide range of external holders and boring bars; the cylindrical hole with a single‑side countersink (40°–60°) supports secure seating and repeatable indexing. The insert’s 11° clearance reduces rubbing on the flank face, lowering heat generation and helping to maintain dimensional accuracy. This geometry selection is particularly effective for finishing passes where tool rigidity, repeatable seating and minimal vibration are crucial to achieve consistent cycle‑to‑cycle results.

Productivity gains through optimised edge preparation and chip control

Equipped with a one‑sided chipbreaker and the fine edge properties of the cermet grade, this insert is tailored to minimise cutting forces and produce short, controllable chips in many steels. Reduced forces translate into less spindle load and more stable cutting conditions, enabling higher feed consistency and shorter finishing cycles. For process planners, the result is measurable: fewer rework steps and a higher first‑pass yield when turning components that demand tight surface and dimensional specifications.

FAQ

What materials is this insert best suited for?
The CPMT090302 NS9530 insert is a finishing grade optimised for steel; the uncoated cermet NS9530 offers a sharp edge and low cutting forces for high‑quality turned surfaces.

Can this insert be used for both external and internal turning?
Yes, the ISO‑standard CPMT090302 geometry is suitable for external and internal turning when paired with a compatible external holder or boring bar and the correct clamping set.

How does the 0.2 mm corner radius affect surface finish?
A 0.2 mm radius provides a defined cutting edge that reduces burrs and improves surface texture during finishing passes, supporting consistent part tolerances and reduced secondary operations.

What role does the chipbreaker play in finishing operations?
The one‑sided chipbreaker is designed to produce short, controllable chips, lowering cutting forces and heat generation which contributes to process stability and better surface quality.

Is the insert compatible with standard ISO toolholders?
The insert follows ISO geometry conventions (CPMT090302) and is compatible with holders that match its form, clearance angle, tolerance class, fastening and thickness; verification of holder compatibility is recommended before mounting.
