SCMT 09T304 NS9530 — Tungaloy indexable insert for turning, sharp-edge finishing

The SCMT09T304 NS9530 is an ISO-standard square turning insert designed for fine finishing of steel components in continuous-cut applications.

• Sharp-edge cermet for fine finishing
• ISO-standard square shape, 09 size
• Optimised for continuous cuts and small depths
• Through-hole with cylindrical countersink (40°–60°)

High-quality finishing with a sharp cermet grade

The insert is specified as an uncoated cermet grade (NS9530), which delivers a sharp cutting edge and reduced cutting forces for improved surface quality on steel. This composition is chosen to combine good wear resistance with an ability to produce low-roughness finishes during light cuts. As a result, components requiring tight surface-tolerance and consistent roughness values benefit from stable cutting behaviour and longer intervals between reworking.

Reliable holder compatibility and secure clamping

Designed to ISO geometry, the square form and detailed dimensions ensure repeatable compatibility with matching external holders or boring bars. Compatibility is determined by form, relief angle 7°, tolerance class, fastening method, size and plate thickness, so correct pairing with the clamping kit and screws is essential. The insert’s through-hole with cylindrical hole and one-sided countersink (40°–60°) enables secure seating and reliable torque transmission in standard ISO clamping systems.

Optimised for continuous cuts and low-depth finishing passes

With a single-sided chipbreaker and a small corner radius 0.4 mm, the geometry supports continuous cutting and small depths of cut, reducing vibration and promoting stable chip formation. These characteristics lower process variability, improve tool life and help achieve consistent batch-to-batch surface quality. The design is particularly suitable where modest material removal and excellent surface finish are the primary objectives.

Practical integration into workshop tool systems

The insert is part of an ISO insert system and is intended to be used with a matching external holder or boring bar, plus the appropriate shim/clamp set and spare screws. Its 3.97 mm plate thickness and square 09 size make it straightforward to fit into common turning tool families, simplifying inventory and tool-change procedures. The system approach supports efficient changeover and predictable machining outcomes, enabling smoother production planning in finishing operations.

FAQ

What material is this insert optimised for?
The NS9530 grade is optimised for finishing on steel; the uncoated cermet composition emphasises low cutting forces and high surface quality with continuous cuts.

Which geometry and size does the insert use?
This is a square ISO insert in 09 size with a 90° included angle and 0.4 mm corner radius, compatible with ISO external holders designed for the SCMT family.

How does the through-hole design affect clamping?
The through-hole with cylindrical hole and one-sided countersink (40°–60°) provides stable seating and predictable clamp engagement in standard ISO clamping arrangements.

Is this insert suitable for interrupted cuts?
The design and sharp-edge cermet are optimised for continuous, light finishing cuts; interrupted or heavily interrupted conditions may require a different geometry or grade.

What does the system package require for installation?
Installation requires a matching external holder or boring bar, plus the appropriate shim/clamp set and replacement screws to ensure correct seating and torque transmission.
