VBMT160408-PF NS9530 — ISO turning insert for finishing, Tungaloy

VBMT160408-PF NS9530 is a rhombic ISO turning insert designed for finishing operations on steel, offering a sharp edge geometry and a PF chipbreaker for continuous, fine cuts.

• Finished-grade cermet for superior surface finish
• Sharp cutting edge with low cutting forces
• ISO rhombic shape, 16 mm, 0.8 mm nose radius
• Cylindrical hole with 40°–60° single-sided countersink

High-precision finishing for steel components

The grade is an uncoated cermet designated NS9530, optimised for finishing on steel with a pronounced focus on surface quality. Its sharp cutting edge and the PF chipbreaker reduce cutting forces and produce minimal built-up edge, which translates into improved part finish and reduced rework. For operations requiring consistent small depths of cut and continuous cutting, this insert delivers predictable results and helps maintain tight tolerances during serial production.

Stable machining and straightforward holder compatibility

Manufactured to the ISO profile, the insert’s rhombic geometry and defined parameters — including a 5° clearance angle, 16 mm insert size and 4.76 mm thickness — ensure straightforward compatibility with standard external holders and boring bars. Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; selecting a matching holder and clamping set confirms reliable positioning and repeatability. The 0.8 mm nose radius supports fine detail without compromising edge strength.

Practical advantages, tool selection and process benefits

The combination of cemented carbide construction and the NS9530 finishing grade offers a balance between edge robustness and sharpness, reducing machining forces and enabling smoother feeds. This leads to lower vibration sensitivity and contributes to longer effective tool life under suitable conditions. When choosing inserts, pair the PF chipbreaker and the NS9530 grade with stable setups for turning and light to moderate feeds; this approach yields the best compromise between surface integrity and productivity while minimising downstream finishing work.

FAQ

What materials is this insert suitable for?
The VBMT160408-PF NS9530 is a finishing cermet insert optimised for steel; the NS9530 grade provides a sharp cutting edge and low cutting forces for improved surface quality on steel components.

How does the PF chipbreaker influence cutting behaviour?
The PF chipbreaker on the VBMT160408-PF NS9530 promotes controlled chip formation for continuous cuts, lowers cutting forces and supports consistent, fine feeds that enhance surface finish.

Which holder features are required for correct fitment?
Correct fitment depends on holder form, clearance angle, tolerance class, fastening method, size and thickness; pairing the ISO rhombic insert with a matching external holder or boring bar ensures repeatable positioning for the VBMT160408-PF NS9530.

Is this insert suitable for internal turning as well as external turning?
Yes, the ISO-profile and geometric data make the insert appropriate for both external and internal turning operations when the toolholder geometry and clamping ensure rigidity.
