VBMT160408-TM NS9530 (VBMT 160408) — Turning • Tungaloy

VBMT160408-TM NS9530 is an ISO‑type rhombic indexable insert for finishing in turning applications, engineered for low cutting forces and high surface quality.

• ISO rhombic insert, VBMT form
• Uncoated cermet grade NS9530 for finishing
• 0.8 mm corner radius for fine surface results
• Cylindrical hole with single‑side countersink

Optimised finishing performance for steel turning

The insert is formulated as an uncoated cermet in grade NS9530, designed specifically for finishing of steel where a sharp cutting edge and low cutting forces matter. That combination reduces the tendency for built‑up edge and supports steady machining at small depths of cut, delivering a consistently improved surface finish. For production environments where repeatability and minimal rework are priorities, the fine edge geometry and material match contribute to predictable part quality and reduced time spent on secondary operations.

Precision geometry that supports secure clamping and repeatability

The rhombic VBMT geometry with a 35° included angle and a 5° clearance angle provides an effective compromise between cutting stability and accessibility for external and internal turning. The insert’s cylindrical hole with a single‑side countersink (40°–60°) ensures secure clamping and correct seating in compatible toolholders; compatibility is determined by form, clearance angle, tolerance class, fixing method, size and thickness. The 4.76 mm plate thickness and 16 mm size add rigidity in typical finishing setups, helping to maintain tool life under continuous cut conditions.

Practical process benefits for workshop productivity

With the TM chipbreaker and the cermet’s inherent properties, chip behaviour during finishing becomes more manageable, which in turn supports uninterrupted cycles and lowers the risk of surface damage. The insert is particularly suitable for continuous cuts and small depths of cut, where the emphasis is on achieving high-quality surfaces rather than heavy metal removal. Selecting this insert can reduce tool change frequency and stabilise cycle times, improving overall process economy without sacrificing component quality.

Clear advantages for specifying in production

Specifying this grade and geometry brings two immediate benefits: a reproducible fine finish on steel components and reduced cutting forces that lower spindle and fixture loads. The ISO standard form simplifies procurement and replacement across machines that accept VBMT‑style inserts, while the uncoated cermet chemistry offers a defined behaviour under finishing conditions. For manufacturers prioritising surface integrity and dimensional consistency, this insert represents a focused solution that supports efficient series production.

FAQ

Which materials are best machined with this insert?
The VBMT160408‑TM NS9530 is optimised for steel finishing; the uncoated cermet composition delivers a sharp edge and low cutting forces that favour continuous cuts and small depths of cut in steel components.

What benefit does the TM chipbreaker provide?
The TM chipbreaker on this insert improves chip control during finishing operations, producing short, manageable chips and reducing the risk of surface damage and edge build‑up when using the NS9530 grade.

How is holder compatibility determined for this insert?
Compatibility depends on the insert form (VBMT), clearance angle (5°), tolerance class, clamping method, size (16 mm) and thickness (4.76 mm); ensure the toolholder matches the VBMT geometry and the cylindrical hole/countersink configuration.

How does the 0.8 mm corner radius affect component finish?
A 0.8 mm radius balances edge strength with the ability to achieve a fine surface finish; it reduces cutting forces compared with larger radii and is particularly effective for finishing passes with small depths of cut.

Is this insert coated?
No — the NS9530 grade supplied with this VBMT insert is an uncoated cermet designed for finishing steel where a sharp edge and low cutting forces are required.
