Square 09 format with 0.4 mm corner radius
Single-sided chipbreaker for continuous cuts
11° clearance angle and 3.18 mm thickness

Precise finishing with a cermet edge for steel

The core advantage of the insert lies in the NS9530 composition: an uncoated cermet designed specifically for finishing operations on steel. The combination of a sharp cutting edge and the cermet microstructure reduces friction and produces a consistently high surface finish, while lowering cutting forces. This makes the component particularly suited to operations where small depth of cut and continuous chips are required. For process planners, the reduced cutting force translates into less vibration and more predictable dimensional control during longitudinal, facing and profiling operations.

Multidirectional turning system compatibility for fewer tool changes

This insert is intended for use in the AddMultiTurn model series, a multidirectional turning system that integrates holder, indexable inserts and clamping. The system design enables several machining directions with a single tool body, cutting down on changeovers and set-up time. As a result, production workflows benefit from increased uptime and improved throughput without compromising finish quality. The insert’s geometry supports reliable clamping and repeatable indexation within the system.

Geometry engineered for repeatable accuracy

The insert’s square 09 format with a 0.4 mm corner radius provides a blend of edge strength and fine finishing capability. With a thickness of 3.18 mm and an 11° relief angle, the geometry supports stability under light finishing passes while maintaining the sharpness needed for low cutting forces. The single-sided chipbreaker is configured for continuous chips and small feed conditions, improving chip control and helping to maintain uninterrupted cutting performance. These features contribute to consistent part-to-part surface quality and predictable tool life.

Application guidance and operational benefits

Optimised for turning tasks such as longitudinal turning, facing and profiling, this insert is particularly effective where a fine surface and tight tolerances are priorities. The uncoated cermet grade favours continuous-cut conditions and small depths of cut; the insert’s design supports steady chip formation and stable cutting forces. For production environments seeking predictable finishing, the insert offers a cost-effective balance of performance and tool life while simplifying insert selection within the AddMultiTurn system. For further machining parameters or setup recommendations, technical consultation is available to match the insert to the specific machine and material combination.

FAQ

What machining tasks suit this insert best?
The SPGR090304 NS9530 insert from Tungaloy is optimised for finishing operations in turning, including longitudinal turning, facing and profiling on steel, where continuous cuts and fine surface quality are required.

Is the insert suitable for interrupted cuts?
The NS9530 cermet grade and the square geometry are primarily designed for continuous cutting and small depths; interrupted cuts are not the intended primary application for this insert.

How does the single-sided chipbreaker affect chip control?
The single-sided chipbreaker on the SPGR090304 promotes consistent chip formation under continuous-cut conditions, improving evacuation and reducing the risk of chip entanglement during finishing passes.

Can this insert be used in the AddMultiTurn system without adapter changes?
The insert is part of the AddMultiTurn series and is dimensioned for integration into the corresponding holders and clamping systems; verification of holder compatibility is advised before mounting.

What material grade is recommended for steel finishing?
Tungaloy’s NS9530 is an uncoated cermet grade formulated for steel finishing, offering a sharp edge, low cutting forces and improved surface quality.
