CCMT 09T308 NS9530 indexable turning insert by Tungaloy — uncoated cermet, rhombic 80° geometry

CCMT09T308 is an ISO-standard indexable turning insert designed for finishing operations in steel, suitable for both external and internal turning applications.

• ISO 09 insert for external and internal turning
• Uncoated cermet NS9530 for superior finish
• Rhombic geometry with 80° included angle
• 0.8 mm corner radius for fine finishing

Achieve consistently superior surface finish with low cutting forces

The uncoated cermet grade NS9530 is formulated as a finishing grade for steel, combining ceramic hardness with a metallic binder to maintain a sharp cutting edge and resist heat during continuous cuts. This results in low cutting forces, reduced tendency to vibrate and a measurable improvement in surface integrity compared with standard carbide grades. For operations with small depths of cut and stable setups, the insert’s material composition promotes repeatable part quality and fewer secondary finishing steps.

Secure fit and defined geometry for reproducible machining

The insert follows ISO-standard dimensions and must be matched to an appropriate toolholder; compatibility depends on insert form, relief angle, tolerance class, clamping and thickness. With a 7° relief and a rhombic profile that yields an 80° included angle, the geometry balances cutting edge strength and access to tight contours. The plate thickness of 3.97 mm and a 0.8 mm radius are optimised for finishing passes where a narrow contact zone is required to preserve dimensional accuracy and achieve consistent part faces.

Practical integration in the turning system and versatile finishing use

As part of an ISO turning system, the insert is used with a matching external holder or boring bar plus a shim and clamping kit; the central hole with a cylindrical bore and one-sided countersink (40°–60°) ensures reliable positioning and torque transmission. The single-sided chipbreaker provides controlled chip formation in continuous cuts, simplifying chip evacuation and reducing risks in long turning cycles. The carbide substrate remains robust under typical finishing speeds, making the insert a practical choice for machine shops seeking productive, high-quality turning in steel.

FAQ

Which materials is this insert best suited for? The CCMT09T308 NS9530 insert from Tungaloy is optimised for machining steel, particularly where a finishing grade with low cutting forces and excellent surface quality is required.

Can the insert be used for internal as well as external turning? Yes, the rhombic geometry and ISO sizing make the insert suitable for both external and internal turning when paired with the correct holder and mounting accessories.

What does the 0.8 mm radius mean for surface finish? A 0.8 mm corner radius provides a small contact area that helps achieve a finer surface finish while maintaining edge strength appropriate for finishing passes.

How is the insert secured in the holder? The insert features a central cylindrical hole with a one-sided countersink (40°–60°); secure clamping requires a matching toolholder, shim and clamping kit to ensure positional accuracy and stable cutting conditions.
