CCGT 09T304 NS9530 – ISO rhombic turning insert, 7° clearance (Tungaloy)

The CCGT 09T304 NS9530 is an ISO rhombic turning insert designed for finishing operations on steel, offering a sharp cutting edge and stable chip control for continuous turning with small depths of cut.

• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge for low cutting forces
• ISO rhombic CCGT09 with 7° clearance
• Single-sided chipbreaker; hole with countersink

Achieve high-precision finishing with low cutting forces and superior surface quality

The uncoated NS9530 cermet is formulated for finishing steel components where surface integrity matters. Its sharp edge geometry produces low cutting forces, which reduces tool-induced vibration and helps maintain tight dimensional tolerances. In practice, this results in a smoother surface finish and less need for secondary operations when machining continuous cuts and shallow depths of cut. For shops focusing on consistent part quality, the combination of a fine cermet grade and a small corner radius delivers measurable gains in finish and repeatability.

Ensure reliable seating and compatibility with ISO holders for consistent clamping

Compatibility with a toolholder depends on form, relief angle, tolerance class, clamping method, size and thickness. The rhombic insert features a 7° clearance angle and is supplied with a cylindrical hole plus a single-sided countersink (40°–60°), so correct matching to the clamping seat is essential. The ISO designation guarantees interchangeability with standard holders; however, checking the holder’s seat geometry and screw style ensures the insert is clamped securely and performs as intended. Proper seating minimises micro-movement, improving tool life and part consistency.

Boost productivity with predictable chip control and application-focused geometry

The insert’s single-sided chipbreaker and compact 0.4 mm corner radius are optimised for finishing passes, promoting controlled chip formation and stable cutting even at modest feed rates. A plate thickness of 3.97 mm contributes to rigidity in the cutting zone, while the rhombic form and 80° included angle provide accessibility for external and internal turning. Together these features reduce process variation and the likelihood of rework, delivering a more economical production flow for short-cycle or high-mix environments where surface quality and repeatability are priorities.
