SNMG120412 NS9530 indexable turning insert for finishing — Tungaloy

SNMG120412 NS9530 is an ISO-format indexable turning insert optimised for finishing operations in steel, featuring a sharp cutting edge and a double-sided chipbreaker.

• ISO-standard indexable insert
• Uncoated cermet finishing grade
• Low cutting forces and sharp edge
• Double-sided insert with cylindrical hole

Exceptional finishing performance for steel turning

The insert is produced in the uncoated cermet grade NS9530, developed for light finishing cuts where a sharp cutting edge and low cutting forces are essential. This composition reduces built-up edge and promotes a consistent surface texture on steel components, making the insert particularly suitable for continuous cutting and small depths of cut. The result is a high surface finish with reduced rework and predictable process outcomes.

Seamless integration into ISO tooling systems

Built to the ISO designation SNMG120412, the geometry and tolerance class ensure reliable fitment with compatible holders and boring bars. The square form with a 1.2 mm corner radius and a 90° lead angle provides predictable tool engagement and accessible edge positions. A cylindrical hole allows positive clamping, and the double-sided design doubles the available cutting edges for economical usage. Overall component dimensions and the 4.76 mm plate thickness contribute to stable mounting and repeatable results in production setups.

Process reliability and cost-effective productivity

Choosing a finishing-grade insert like this improves cycle consistency and surface quality while maintaining tool life under the intended conditions. The double-sided chipbreaker supports stable chip formation in finishing cuts, reducing the risk of chatter and enabling steady feed rates. As an ISO-format insert from Tungaloy, it is designed to offer process security and predictable edge performance, helping to lower tooling costs per part and to maintain throughput in serial turning operations.

FAQ

What machining operations is this insert intended for?
This SNMG120412 NS9530 Tungaloy indexable turning insert is designed primarily for finishing turning operations in steel, favouring continuous cuts and small depths of cut.

How many usable cutting edges does the insert provide?
The insert is double-sided, offering multiple usable edges before replacement is required, which improves cost efficiency per edge.

Is the grade suitable for interrupted cuts?
The NS9530 is a finishing-grade uncoated cermet optimised for continuous cutting; interrupted cuts may reduce edge life compared with continuous finishing applications.

What holder features are required for correct compatibility?
Compatibility is determined by insert form, relief angle, tolerance class, clamping method, size and thickness; use ISO-compatible holders designed for SNMG inserts.

Does the insert include a chipbreaker, and what is its function?
Yes — the double-sided chipbreaker assists in producing stable chips during finishing cuts, enhancing surface quality and reducing the risk of chip-related disruptions.
