Take advantage of the combination of a finishing-grade cermet, a small 0.4 mm corner radius and ISO compatibility to achieve consistently fine surface quality and stable chip formation in turning operations; order directly via Metav Werkzeuge or consult our specialists for application-specific guidance.

VBMT 160404 NS9530 VBMT160404-PF – ISO rhombic turning insert for finishing, Tungaloy

The VBMT160404-PF NS9530 is an ISO-standard rhombic insert designed for precision finishing of steel components in turning applications, offering a sharp cutting edge and low cutting forces for continuous light cuts.

• Uncoated cermet grade NS9530 for superior finish
• Low cutting forces for fine finishing cuts
• ISO rhombic shape VBMT160404 – 5° relief
• Cylindrical hole with one-sided countersink

Delivering consistent high-surface finishes with cermet technology

The insert’s NS9530 cermet composition is tailored for finishing operations on steel, combining edge sharpness with wear resistance to produce high surface finish and accurate dimensional results. The 0.4 mm corner radius supports smooth transitions on external contours while maintaining low cutting forces, which reduces vibration and load on the toolholder. For continuous light cuts and small depths of cut the uncoated cermet provides a stable cutting edge and predictable tool life, making it a reliable choice for components where surface integrity is critical.

Seamless ISO compatibility and reliable clamping for production use

Manufactured to ISO dimensions, the rhombic VBMT form and the 16 mm inscribed circle ensure straightforward matching with standard external holders and boring bars. The insert thickness is 4.76 mm and the relief angle is 5°, while the insert features a cylindrical hole with a one-sided countersink (40°–60°) for secure clamping. When assembling a cutting system, ensure the holder matches form, relief, tolerance class, fastening method, size and thickness; the complete system typically comprises the ISO insert, a suitable external holder or boring bar, a shim/clamp set and replacement screws to guarantee repeatable seating and consistent process performance.

Application guidance and operational benefits in turning

The PF chipbreaker geometry is optimised for finishing: it supports compact, easily controllable chips and works best with continuous cuts and small material removals where the aim is superior surface quality rather than high metal removal rate. The insert’s geometry, including a 35° included angle and 0.4 mm corner radius, reduces edge loading and helps maintain a sharp flank for longer, which is especially advantageous in serial finishing and precision components. Selecting this finishing grade together with appropriate cutting parameters leads to lower rework rates and steadier process windows, supporting efficient and predictable machining.

FAQ

What materials is this insert suited for?
The NS9530 finishing grade is formulated for turning steel, providing a sharp edge and low cutting forces for high-quality surface finishes.

What does the PF chipbreaker do?
The PF chipbreaker promotes compact, controllable chips during finishing cuts and supports consistent surface quality when using small depths of cut and continuous feed.

How is the insert clamped?
The insert has a cylindrical hole with a one-sided countersink (40°–60°) and is designed for secure clamping in compatible ISO holders; use the correct shim/clamp set and screws for repeatable seating.

Which holders are compatible with this ISO insert?
Holders and boring bars that accept VBMT160404 ISO inserts — matching form, clearance, tolerance class, fastening, size and thickness — are compatible for reliable operation.

What corner radius and angles does the insert have?
The insert features a 0.4 mm corner radius, a 5° relief angle and a 35° included angle, which together favour finishing performance and edge stability.
