CCGT 09T304 NS9530 ISO turning insert — finishing grade (Tungaloy)

CCGT 09T304 NS9530 is an ISO‑standard rhombic turning insert designed for finishing turning of steel with a sharp, uncoated cermet cutting edge and a 0.4 mm nose radius.

• NS9530 cermet, uncoated finishing grade
• Sharp edge for low cutting forces
• Rhombic ISO CCGT 09T304, 80° geometry
• Cylindrical hole with 40°–60° countersink

High‑precision finishing performance for consistent surfaces

The NS9530 uncoated cermet grade delivers a sharp cutting edge tailored for fine finishing operations. Its geometry and edge preparation lead to low cutting forces, which reduces chatter and tool deflection and therefore improves dimensional stability on external and internal turns. For shops prioritising surface integrity, the insert supports continuous cuts and small depths of cut, resulting in a reliably high surface finish without resorting to additional passes.

Design and mounting features that simplify tool selection

The insert follows the ISO CCGT form and is compatible with standard external holders or boring bars; compatibility is governed by form, relief angle, tolerance class, fastening, size and thickness. The insert has a rhombic shape with an 80° included angle, a 0.4 mm nose radius and a 7° relief angle, and is supplied with a cylindrical hole and a one‑sided countersink (40°–60°) for secure clamping. These measurable characteristics make holder matching straightforward and reduce setup time in production environments.

Production advantages and economical operation

Using an uncoated cermet finishing grade offers low friction at the cutting edge and excellent edge retention on steels, which translates into fewer interruptions for tool changes and a more economical machining cycle. The combination of sharp geometry and the NS9530 substrate provides consistent chip formation for finishing feeds, supporting higher process reliability and predictable part outcomes. The insert’s construction enables efficient batch finishing where uniformity and repeatability are required.

Application guidance and material suitability

This insert is optimised for turning steel in finishing applications; choose the NS9530 grade and the matching single‑sided chipbreaker for workpieces where a fine surface and low cutting forces are priorities. The system typically consists of the ISO insert, a matching external holder or boring bar, a support or clamp set and suitable fixing screws. For less experienced users, matching the relief angle, tolerance class and clamping method to the holder specification is decisive for achieving the expected results.

FAQ

What machining tasks is this insert designed for? This insert is intended for finishing turning of steel; the NS9530 uncoated cermet grade and rhombic geometry make it suitable for external and internal finishing operations.

Which holder types are compatible with the CCGT 09T304 NS9530 insert? Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; the insert is designed for standard external holders and boring bars that accept ISO CCGT‑style inserts.

How does the NS9530 grade affect cutting behaviour? The NS9530 uncoated cermet provides a sharp edge and reduced cutting forces, promoting stable chip formation and superior surface finish in finishing cuts.

What clamping feature does the insert have? The insert is supplied with a cylindrical hole and a one‑sided countersink (40°–60°) to ensure reliable clamping in compatible holders.

Is the insert suitable for interrupted cuts or heavy roughing? This grade and geometry are optimised for continuous finishing cuts and small depths of cut; for heavy roughing or highly interrupted cuts, a different grade or geometry should be selected.
