TNMG 160408 NS9530 Tungaloy turning insert

A TNMG160408 NS9530 Tungaloy insert designed for precision finishing in steel turning applications with a sharp cermet grade for low cutting forces and excellent surface quality

• Uncoated cermet grade NS9530
• Fine corner radius R0.8 for high finish
• Double-sided chipbreaker for consistent chips
• ISO TNMG160408 triangular insert, 60°

Precision finish for demanding turning operations

The combination of an uncoated cermet cutting material and a finely honed edge provides a clear advantage when the priority is surface quality rather than heavy stock removal. The NS9530 grade is engineered as a finishing grade for steels, delivering low cutting forces and a sharp edge that supports continuous cuts and small depths of cut. This results in a reduction of vibration at the tool–workpiece interface and contributes to a repeatable surface finish without resorting to excessive machine adjustments. The result is less time spent on downstream polishing and predictable part quality.

Stable chip control and consistent process results

A double-sided chipbreaker paired with the sharp cermet substrate stabilises chip formation during continuous turning, which reduces the risk of built-up edge and helps maintain tool life under finishing conditions. The insert’s geometry supports controlled chip flow even at low feed rates, so operators experience fewer interruptions and maintain steady cycle times. Where reproducible results are essential, the predictable behaviour of this insert contributes to process reliability and fewer rejects in serial production.

Dimensional reliability and straightforward mounting

Conformity to the ISO designation TNMG160408 ensures compatibility with standard triangular turning holders; the insert is supplied with a cylindrical hole and nominal thickness of 4.76 mm, facilitating secure clamping and repeatable positioning. The 0° clearance angle and the 60° included angle of the triangle together define the engagement geometry and influence cutting forces and tool reach in external and internal turning. The combination of corner radius R0.8 and the specified geometry makes the insert particularly suitable where close tolerances and consistent part profiles are required.

Application guidance for improved productivity

This indexable insert is optimised for finishing steel components with continuous cutting conditions and modest depths of cut. Selecting NS9530 as an uncoated cermet grade is a deliberate choice for operations where a sharp cutting edge and fine surface finish are decisive. For best results, pair the insert with a rigid holder and moderate spindle speeds to exploit the low cutting forces; choosing the correct chipbreaker version and matching feed rates will extend effective tool life. For assistance in selecting the right combination of holder, screw and clamping set, technical consultation is available to align insert choice with machining strategy and production targets.
