CPMT090304 NS9530 Tungaloy indexable turning insert — uncoated cermet finishing grade for turning

A CPMT090304 NS9530 Tungaloy insert designed for precision external and internal turning, optimised to deliver low cutting forces and superior surface finish in continuous finishing passes

• Uncoated NS9530 cermet for finishing steel
• 80° rhombic geometry with 0.4 mm corner radius
• Single-sided chipbreaker for continuous cuts
• ISO-compatible insert with cylindrical hole and countersink

Optimised finishing performance for steel turning

The CPMT090304 NS9530 Tungaloy insert is an uncoated cermet developed as a finishing grade for steel, offering a sharp cutting edge that reduces friction and delivers a markedly high surface finish. Its composition and edge form produce low cutting forces, which is particularly beneficial when machining thin-walled components or delicate features where minimising deformation is critical. The specification targets continuous cut conditions and small depths of cut, translating into predictable results when finishing turned components and reducing the need for downstream rework.

Geometry that improves dimensional accuracy and chip behaviour

Engineered with an 80° included angle and a 0.4 mm corner radius, the rhombic form provides an effective balance between edge strength and the fine detail required at the finish stage. The single-sided chipbreaker supports controlled chip formation under smooth, continuous cutting, which helps maintain consistent cutting forces and protects the part surface. The 11° clearance angle reduces rubbing at the flank, aiding dimensional stability and prolonging effective tool life, while the countersunk centre hole ensures secure and repeatable clamping in compatible holders.

ISO compatibility for quick tool changes and steady production flow

Designed as part of an ISO-standard insert family, the component integrates into common turning systems where compatibility is governed by shape, clearance, tolerance class, fastening and thickness. The 3.18 mm plate thickness and the cylindrical hole with a one-sided countersink (40°–60°) facilitate straightforward seating and fastening in matched holders, minimising setup time and maintaining process reliability. For workshop planning, the clear specification supports predictable inventory management and swift replacement during production runs.

FAQ

Which materials is this insert best suited for?
The CPMT090304 NS9530 insert is specified as a finishing grade for steel and is optimised to produce low cutting forces and superior surface finishes on continuous turning operations.

What are the key geometric values to check when selecting a holder?
Check the 80° included angle, plate size 09, 3.18 mm thickness and 0.4 mm corner radius to ensure the chosen holder matches the CPMT090304 geometry and secures the insert correctly.

How does the chipbreaker affect machining?
The single-sided chipbreaker on this insert promotes controlled chip formation during continuous cuts, improving chip control and contributing to consistent surface quality with reduced risk of chip interference.

Is the insert suitable for internal turning as well as external turning?
Yes; the design and cutting edge properties of this indexable insert make it suitable for both external and internal finishing operations under the recommended cutting conditions.

What clamping interface does the insert use?
The insert is supplied with a cylindrical centre hole and a one-sided countersink (40°–60°), intended for secure clamping in compatible ISO holders and bores
