VBMT 160402 NS9530 ISO turning insert for finishing — Tungaloy

The VBMT160402-TM NS9530 is an ISO rhombic turning insert optimised for finishing of steel, combining an uncoated cermet grade with a sharp cutting edge for continuous cuts and fine surface quality

• Uncoated cermet grade NS9530 for finishing
• Sharp edge geometry for low cutting forces
• ISO VBMT form with 4.76 mm thickness
• Cylindrical hole with 40°–60° countersink

Precise finishing where low cutting forces and surface quality matter

The uncoated cermet grade NS9530 is engineered as a finishing grade for steel, offering a sharp cutting edge that reduces cutting forces and delivers an improved surface condition. In practice, this means fewer vibration-related marks and smaller burr formation during continuous turning operations. The combination of a fine 0.2 mm nose radius and the cermet substrate leads to a stable cutting action at the small depths of cut typically used for finishing, enabling consistent part-to-part reproducibility and longer intervals between tool changes. This performance profile supports higher first-pass quality and reduced rework in precision turning tasks.

Secure clamping and straightforward compatibility with ISO toolholders

The rhombic plate geometry (VBMT), a central cylindrical hole with a single-sided countersink (40°–60°) and an ISO code of 160402 ensure the insert integrates reliably into standard ISO holders. The specified 4.76 mm thickness and the clearance angle of 5° together define the seating and stability in the pocket, reducing the likelihood of micro-movements under load. Compatibility depends on plate form, clearance angle, tolerance class, fastening method, size and thickness; these parameters simplify selection of a matching clamping set or replacement screw and make the insert suitable for quick index changes on automatic tool changers, supporting efficient shop-floor logistics.

Application guidance to extract consistent finishing results

Designed primarily for external and internal turning, the insert performs best in continuous cutting with light to moderate feed and small depth of cut, where the NS9530 grade reveals its advantages in surface quality and tool life. Select the TM chipbreaker when a balanced chip formation is required for the chosen steel and machining stability. The body material, cemented carbide, provides the necessary substrate strength while the cermet topography promotes a crisp edge. For practical set-up, ensure the holder offers correct lead and clearance, check the seat for cleanliness, and use appropriate coolant strategy as dictated by the part geometry and material to maintain consistent cutting conditions and repeatable results.

FAQ

Which materials is this insert best suited for? The VBMT160402-TM NS9530 is a finishing cermet grade developed primarily for steel machining, where it delivers low cutting forces and superior surface finish during continuous cuts.

What is the nose radius and how does it influence the finish? The nose radius is 0.2 mm; this fine radius reduces peak cutting loads and helps achieve a smoother surface profile, particularly in finishing passes on turned components.

How is the insert secured in a toolholder? Retention relies on the ISO VBMT form, the central cylindrical hole with a one-sided countersink (40°–60°) and the correct seat geometry; compatibility is determined by form, free angle, tolerance class, fastening, size and thickness.

Can this insert be used for internal turning? Yes; the insert is suitable for both external and internal turning operations provided the correct holder and chipbreaker are selected for the workpiece geometry and machining stability.

What are the ordering references for this item? Manufacturer article number 6951508, SKU 6951508-Tungaloy and manufacturer SKU TUN6951508 identify the Tungaloy VBMT160402-TM NS9530 insert for procurement and logistics.
