VCMT160402-TM NS9530 – ISO rhombic turning insert for finishing, Tungaloy

The VCMT160402-TM NS9530 is an ISO‑standard rhombic turning insert designed for finishing operations on steel, supplying a sharp uncoated cermet grade with a low cutting‑force geometry for continuous cuts.

• ISO rhombic insert, 16 mm size
• Sharp uncoated cermet grade NS9530
• Cylindrical hole with single-sided countersink
• Low cutting forces for excellent surface finish

Precision finishing with a dedicated cermet grade

The NS9530 finishing grade is an uncoated cermet optimised for steel, offering a very sharp cutting edge and reduced cutting forces that translate into improved stability and repeatable surface quality. For continuous turning and small depths of cut this composition reduces vibration and burr formation, which means fewer secondary operations and more parts meeting tolerance the first time. The combination of a true finishing geometry and the TM chipbreaker delivers controlled chip flow and consistent edge life even under stable machining conditions.

Accurate fit and clamping for consistent performance

Compatibility with the clamping system is determined by the insert form, relief angle, tolerance class, mounting method, size and thickness. This rhombic shape in 16 mm size with a thickness of 4.76 mm and a 7° relief is intended for holders that match ISO dimensions. The insert features a cylindrical hole with a single‑sided countersink (40°–60°) and a 0.2 mm corner radius, helping to centre and secure the cutting edge precisely in the seat. Correct pairing of insert and holder reduces runout and ensures the mechanical conditions required for fine finishing are met, thereby stabilising process parameters and minimising rejects.

Productivity gains and practical application advice

As a finishing grade, this insert is aimed at operations where surface integrity and dimensional accuracy are priorities. The low cutting forces reduce tool‑induced deflection, enabling tighter tolerances and higher effective feed stability. In practice, selecting the TM chipbreaker and the NS9530 grade for steel turning results in efficient chip control during continuous cuts, while the sharp cermet edge supports superior surface roughness values. For workshops evaluating holder choices or cutting data, Metav Werkzeuge’s technical team can advise on the ideal nominal speeds and feeds to balance tool life and cycle time.

FAQ

What materials is this insert best suited for?
The insert grade NS9530 is formulated for finishing turning of steel; the uncoated cermet composition provides a sharp edge and low cutting forces for superior surface finish.

How does the TM chipbreaker affect machining?
The TM chipbreaker on this rhombic insert controls chip form during continuous cuts, improving evacuation and reducing the risk of chip interference in finishing operations.

Which holder features are essential for correct mounting?
Holders must match the ISO form, relief angle, tolerance class, mounting and insert thickness to ensure correct clamping and repeatable seating of the insert.

What does the 0.2 mm corner radius mean for surface quality?
A 0.2 mm corner radius reduces cutting stress and helps achieve finer surface roughness while still providing a small, defined edge suitable for finishing passes.

Is this an uncoated or coated insert, and what does that imply?
This is an uncoated cermet grade; the lack of coating results in a very sharp edge tailored to finishing and low cutting forces rather than the wear resistance typically provided by coated grades.
