VBMT 160404 NS9530 ISO rhombic turning insert for finishing by Tungaloy

VBMT 160404 NS9530 is an ISO-indexable rhombic insert designed for finishing operations in turning, optimised for continuous cuts and small depths of cut

• ISO rhombic insert for finishing
• Grade NS9530 uncoated cermet
• 0.4 mm nose radius, sharp edge
• 5° relief angle, 16 mm size

Low‑force finishing for superior surface quality

The NS9530 uncoated cermet grade is tailored as a finishing sort for steel, offering a sharp cutting edge that promotes low cutting forces and a high surface finish. Cermet combines ceramic hardness with metallic toughness, which maintains edge stability under continuous cutting and small depths of cut; this characteristic reduces the need for repetitive passes and supports predictable part quality. The geometry and edge preparation favour delicate material removal, so fine surface integrity can be achieved without aggressive feeds or depths.

Precision fit within the ISO system for reliable clamping

Compatibility with toolholders is determined by form, relief angle, tolerance class, clamping, size and thickness, so the ISO designation ensures straightforward integration into established tool systems. The insert is rhombic with an included angle of 35°, a nominal size of 16 mm, and a plate thickness of 4.76 mm, while the 0.4 mm nose radius supports tight dimensional control. The central mounting feature is a cylindrical hole with a one‑sided countersink (40°–60°), providing secure seating in compatible external holders and boring bars. These defined parameters make selection and setup reproducible across shifts and machines.

Practical system setup to support chip control and process stability

Process reliability is achieved by pairing the insert with a suitable chipbreaker, holder and clamping set; this series is supplied as an ISO indexable plate to be used with a matching external holder or boring bar, plus an underlay/lock set and replacement screws where required. The plate carries a chipbreaker 24, and the system approach allows chip formation and evacuation to be tuned to the workpiece material and operational stability. When the grade, chipbreaker and cutting data are aligned to the machining strategy, predictable chip control and consistent component surface quality are obtained while maintaining efficient cycle times.

FAQ

Is this insert suitable for finishing steel? The VBMT 160404 NS9530 by Tungaloy is a finishing grade cermet insert specifically developed for finishing operations in steel, delivering a sharp edge and low cutting forces for improved surface quality.

Which holder characteristics must be checked for compatibility? Compatibility requires matching the ISO form, relief angle, tolerance class, clamping method, size (16 mm) and thickness (4.76 mm); the VBMT 160404-24 format and central hole form determine correct seating in an external holder or boring bar.

What chipbreaker is supplied and how does it affect performance? The plate carries chipbreaker 24; selecting this chipbreaker together with the NS9530 grade helps control chips in continuous cutting and supports consistent finishing at small depths of cut.

Can this insert be used for interrupted cuts? The grade and geometry are optimised for continuous cuts and small depths of cut; interrupted cuts may compromise edge life and surface result compared with continuous turning with VBMT 160404 NS9530.

What are the key dimensions to specify when ordering a holder? Specify the ISO designation VBMT160404-24, size 16 mm, plate thickness 4.76 mm, nose radius 0.4 mm, relief angle 5° and the cylindrical hole with one‑sided countersink (40°–60°) to ensure proper holder selection.
