SNMG120412 NS9530 Tungaloy turning insert — uncoated cermet, 1.2 mm radius

The SNMG120412 NS9530 Tungaloy is an ISO‑standard square turning insert designed for precision external and internal turning, optimised for finishing steel components.

• Uncoated cermet grade NS9530
• Sharp cutting edge for high surface finish
• 1.2 mm corner radius for small depths of cut
• Double-sided insert with cylindrical hole

Precision finishing for demanding steel applications

The uncoated cermet grade NS9530 provides a notably sharp cutting edge that reduces cutting forces and promotes superior surface quality during finishing operations on steel. Its composition is engineered for continuous cutting where low vibration and fine chip formation are priorities, which translates into consistent component geometry and fewer rework cycles. The material and geometry together enable operators to achieve a high-quality finish with reduced feed variations, supporting stable production runs and predictable outcomes.

Improved cutting performance with controlled chip flow

An integrated double-sided chipbreaker and the insert’s sharp edge contribute to efficient chip control and lower cutting loads, especially at small depths of cut. The design supports reliable heat dissipation across repetitive finishing passes, which helps to maintain edge integrity and extend effective tool life. These performance characteristics combine to increase machining productivity by enabling higher throughput with fewer tool changes and more uniform surface results.

Straightforward compatibility and secure mounting

As an ISO‑standard insert in square form, compatibility with toolholders is determined by shape, clearance angle, tolerance class, attachment method, size and thickness. The insert features a cylindrical hole for secure fixing and a 90° corner geometry that simplifies toolpath planning for shoulder and facing operations. With a 1.2 mm corner radius and a plate thickness of 4.76 mm, the component balances edge robustness with the ability to machine small radii and precise contours, making it suitable for fine finishing where dimensional control is essential.

Recommended use and application scope

This insert is targeted at turning operations that prioritise surface quality and repeatability: external and internal finishing passes on steel using continuous cutting strategies and modest material removal per pass. Workshops and production environments seeking predictable finishing results will benefit from the combination of the NS9530 grade and the insert geometry, which together support consistent chip formation and reliable process stability. For changeovers, select a matching ISO holder and ensure clamping torque and tolerance class align with the insert’s specifications to preserve performance.
