VBMT110308-PS NS9530 – ISO turning insert VBMT 110308 for turning by Tungaloy

A VBMT110308-PS NS9530 ISO turning insert designed as a finishing grade for steel, offering a sharp cutting edge, low cutting forces and optimised chip formation for continuous-cut turning operations

• ISO rhombic VBMT 110308 form
• Uncoated cermet NS9530 finishing grade
• Sharp edge for low cutting forces
• Cylindrical hole with single-sided countersink

High-quality finishing with an optimised cermet grade

The insert is manufactured in an uncoated cermet grade (NS9530) developed for finishing operations on steel, delivering a sharp cutting edge and consistent edge stability. This results in reduced vibration and lower cutting forces during continuous turning, which translates into improved surface finish and longer tool life in many setups. The choice of a cermet substrate improves wear resistance at finishing speeds while maintaining low built-up edge tendency, so the machining result is both consistent and reproducible.

ISO compatibility and secure clamping ensure reliable operation

As an ISO‑standard turning plate in the VBMT form, compatibility with toolholders depends on form, relief angle, tolerance class, clamping method, size and thickness. The insert features a 35° lead angle and a 5° relief angle, so matching a corresponding outside holder or boring bar is straightforward. Correct pairing of holder and plate ensures stable seating, repeatable indexation and safe clamping torque values, which are essential for process security and predictable cycle times in production environments.

Geometry tailored to finishing: radius, thickness and hole design

The geometry includes a 0.8 mm corner radius, plate thickness 3.18 mm and plate size 11 mm, making the insert suitable for small depths of cut and fine surface requirements. The PS chipbreaker is tuned to the grade and turning conditions to support continuous chips and prevent edge overload. The central cylindrical hole with a one‑sided countersink (40°–60°) provides reliable clamping and easy positioning when replacing inserts, reducing spindle downtime during tool changeovers.

Practical system notes and selection guidance

The recommended system comprises the ISO insert, a matching outside holder or boring bar, a seating pad or clamping kit and spare screws for safe assembly. When specifying cutting data, favour finishing speeds and modest feeds to exploit the grade’s low cutting forces; the geometry is optimised for continuous cuts and small material removal rates. For uncertain applications, select a chipbreaker and grade variant that match the workpiece stability and feed regime to maintain surface integrity and economical tool consumption.

FAQ

Which materials is this insert intended for?
The VBMT110308‑PS NS9530 is a finishing grade developed primarily for steel machining; the NS9530 cermet substrate provides low cutting forces and high surface quality when turning steels.

What are the key geometry values to match with the holder?
Match the holder to the insert’s 35° lead angle and 5° relief angle, and allow for the 11 mm plate size and 3.18 mm thickness to ensure correct seating and clamping.

How does the PS chipbreaker affect machining?
The PS chipbreaker promotes continuous chip formation suitable for finishing cuts, supporting consistent surface finish and stable cutting forces when combined with the NS9530 grade.
