TNMG160404 NS9530 — ISO turning insert (finishing grade) by Tungaloy

The TNMG160404 NS9530 is an ISO‑standard triangular turning insert optimised for finishing steel, offering a sharp cutting edge and low cutting forces for continuous cuts and small depths of cut.

• Uncoated cermet NS9530 finishing grade
• Sharp cutting edge for fine surface finish
• 0.4 mm nose radius for accurate profiles
• Triangular, double-sided with cylindrical hole

Improved finishing through low cutting forces and sharp edge

The combination of an uncoated cermet grade NS9530 and a purpose‑designed edge geometry reduces friction at the cutting zone, which results in low cutting forces and a consistently high surface finish. For finishing passes on steel, the material and edge integrity of this insert promote fewer built‑up edges and more predictable results during continuous machining. This rational advantage shortens rework time and supports stable cycle times in high‑mix and batch production.

Geometry designed for repeatable accuracy and profile control

The insert’s triangular geometry with a 0.4 mm nose radius and a 60° included angle provides precise profile reproduction while maintaining rigidity in the cutting zone. A 0° rake angle contributes to the sharp cutting action beneficial in light finishing cuts. The double‑sided design with a cylindrical hole ensures secure clamping in ISO holders; compatibility depends on holder form, clearance, tolerance class, fastening method, overall size and thickness, which together determine assembly stability and repeatability.

Material composition and application benefits for steel finishing

Manufactured as an uncoated cermet grade, this insert is tailored to finishing tasks on steel, delivering a balance between wear resistance and sharpness that supports excellent optical and tactile surface quality. The grade’s behaviour under continuous cuts and small depths makes it suitable where minimal cutting forces and reduced vibration are priorities. Explaining the term: cermet combines ceramic and metallic properties to maintain a fine cutting edge at moderate temperatures typical of finishing operations.

Practical integration and recommended system setup

System integration requires matching the insert to an appropriate external holder, underlay or clamping kit and replacement screws; the ISO designation ensures interchangeability when holder geometry and tolerance classes are observed. For best results, select a chipbreaker and insert grade aligned with workpiece stability and the intended feed and depth parameters. If there is any uncertainty about holder compatibility or process windows, our technical team can advise on selection and clamping strategy to safeguard component quality and tool life.

FAQ

Which materials is this insert intended for?
The TNMG160404 NS9530 insert is specified as a finishing grade for steel; the uncoated cermet composition supports low cutting forces and high surface quality in finishing applications.

How is the insert clamped and which holders are suitable?
Clamping depends on ISO‑compatible holders that match the insert’s triangular form, 4.76 mm thickness and cylindrical hole; stability is governed by form, clearance, tolerance class, fastening, size and thickness.

What cutting tasks suit the NS9530 grade best?
NS9530 is optimised for finishing operations with continuous cuts and small depths of cut, where a sharp cutting edge and minimal cutting forces are required to achieve superior surface finish.

Is the insert indexable or reversible?
The double‑sided design permits rotation to an unused edge according to the holder’s clamping method; check holder compatibility for indexing procedures.

What is the ISO designation and article number for ordering?
ISO designation: TNMG160404 (160404); Article number / SKU: 6998219‑Tungaloy (manufacturer item number 6998219).
