TNMG 160408 NS9530 Tungaloy turning insert — uncoated cermet finishing grade

TNMG160408 NS9530 Tungaloy is an ISO-indexable turning insert designed for fine finishing of steel components in turning operations

• TNMG geometry for ISO holders
• Uncoated cermet for high surface finish
• 0° clearance angle for precise finishing
• Double-sided triangular design for cost efficiency

High-quality finishing for steel with an uncoated cermet grade

The NS9530 grade is an uncoated cermet developed for finishing operations on steel, offering a sharp cutting edge, low cutting forces and consistently high surface quality. As a finishing grade, it is optimised for continuous cutting and small depths of cut; this reduces vibration and promotes stable chip formation during low-feed, high-precision passes. The cermet substrate delivers good wear behaviour in finishing conditions while the lack of coating helps maintain a keen edge, which is particularly useful where excellent part appearance and tight tolerance maintenance are required.

Proven geometry and dimensional compatibility for ISO systems

Compatibility with toolholders depends on form, clearance, tolerance class, clamping and the plate dimensions. This insert features a triangular form with a 60° included angle and a 16 mm size, making it suitable for standard ISO holders that accept TNMG profiles. The insert has a cylindrical hole for secure fastening and a thickness of 4.76 mm, supporting rigid clamping. The geometry and tolerance specifics ensure repeatable positioning, simple indexability and predictable tool life when paired with a matching external holder or boring bar and the appropriate clamping set.

Design features that translate into productive turning results

A 0° clearance angle is combined with a 0.8 mm nose radius, delivering a balanced trade-off between edge strength and surface finish capability. The double-sided construction provides two usable edges per side, improving economy in production by extending the number of indexable positions. For finishing passes, the reduced cutting forces of the grade and the sharp edge reduce built-up edge and minimise the risk of surface smearing, which helps maintain dimensional accuracy and reduces downstream polishing or rework.

Practical system considerations and process guidance

The insert is part of a system comprising the indexable plate, a matching external holder or boring bar, an underlay/clamping kit and replacement screws. Selecting the correct chipbreaker in conjunction with the NS9530 grade is important: choose a breaker that matches the workpiece material, the stability of the setup and the type of cut to be carried out. The insert’s uncoated cermet composition suits steady, low- to medium-feed finishing cycles; for interrupted cuts or heavy stock removal, alternative grades or geometries should be considered. Maintenance is straightforward: inspect seating surfaces and clamping hardware at each index change to ensure consistent positioning.

FAQ

What materials is this insert intended for?
The NS9530 grade is designed primarily for finishing operations on steel; the insert excels where a sharp edge and low cutting forces are required.

How many indexable edges are available on the plate?
The triangular, double-sided design provides multiple usable edges, extending service life through economical indexing.

What holder compatibility must be checked before use?
Compatibility depends on form, clearance, tolerance class, clamping style, plate size and thickness — ensure the holder accepts TNMG 160408 geometry.

Is this insert coated?
No — the grade is an uncoated cermet (NS9530), which helps retain a sharp cutting edge suitable for fine finishing.

Which system components are needed to assemble the cutting setup?
A matching external holder or boring bar, an underlay/clamping kit and replacement screws are required to secure the insert for reliable turning performance.
