CPMT 09T308 09T308 NS9530 Tungaloy — 80° rhombic indexable turning insert, uncoated cermet

the CPMT09T308 NS9530 is an ISO-format rhombic insert designed for precision turning and finishing of steel components

• 80° rhombic geometry for versatile turning
• Sharp uncoated cermet grade NS9530 for fine finishes
• Single-sided chipbreaker for continuous cuts
• ISO-compatible for standard turning holders

Consistent finishing performance and process efficiency

The rhombic 80° geometry combined with the NS9530 uncoated cermet grade delivers a stable cutting edge and low cutting forces, making it ideal for continuous finishing passes on steel. The insert’s sharp edge reduces built-up edge formation and helps achieve a superior surface finish with minimal secondary operations. The ISO-conformant form and tolerances ensure interchangeability with standard indexable turning systems, maintaining uptime and simplifying inventory management. The engineered combination of geometry and grade supports higher cutting speeds with predictable tool life, which translates into measurable productivity gains on serial production runs.

Predictable chip control and machinability benefits

Equipped with a single-sided chipbreaker, the insert ensures consistent chip formation during light to moderate depth-of-cut operations, reducing the risk of chip entanglement and supporting automated machining cycles. The 0.8 mm corner radius provides a compromise between edge strength and surface quality, suitable for fine-finishing passes where dimensional stability matters. Although uncoated, the cermet composition enhances wear resistance and maintains a sharp cutting profile for polished surfaces; this makes the insert particularly appropriate for continuous cuts and small material removal rates. For process planning, select holder rigidity, feed and depth to match the finishing intent and material batch.

Compatibility, handling and practical application notes

The ISO designation and the plate’s dimensions — including a 3.97 mm plate thickness and the cylindrical hole with one-sided countersink (40°–60°) — define mounting and clamping requirements; compatibility with a matching clamping set and replacement screws is determined by holder form, free angle and tolerance class. The insert is supplied with a cemented carbide substrate and an uncoated cermet cutting edge suited to steel machining. For setups demanding repeatable surface quality in production, combine this insert with a stable toolholder and fine-tuned feeds; the result is lower rework and consistent part quality across batches.

FAQ

What materials is this insert suitable for machining?
The CPMT09T308 NS9530 insert is optimised for machining steel; the uncoated cermet grade NS9530 offers low cutting forces and high surface quality when used on steel components.

How does the NS9530 grade benefit finishing operations?
NS9530 provides a sharp, wear-resistant cutting edge that supports continuous finishing passes, resulting in improved surface finish and reduced secondary processing when the CPMT09T308 insert is used in a stable setup.

Which holders are compatible with this ISO-format insert?
Compatibility depends on holder form, free angle and tolerance class; the CPMT09T308 fits standard ISO turning holders configured for 80° rhombic inserts with the matching clamping arrangement.

What chip control can be expected with this insert?
The single-sided chipbreaker on the CPMT09T308 promotes controlled chip formation during light to moderate finishing cuts, reducing chip interference and facilitating automated machining.

Can the insert be used for interrupted cuts or heavy roughing?
This insert is a finishing-grade solution; for interrupted cuts or heavy roughing, a different geometry and grade would be preferred to protect edge stability and extend life of tools.
