CCMT09T302 NS9530 Tungaloy ISO turning insert — finishing grade, sharp edge

CCMT09T302 NS9530 is an ISO‑standard rhombic insert designed for external and internal turning, offering a sharp cutting edge and low cutting forces for high‑quality surface finishes.

• CCMT09T302 turning insert by Tungaloy
• Uncoated cermet NS9530 finishing grade
• 0.2 mm corner radius for high surface finish
• Cylindrical hole + 40°–60° countersink

Delivering repeatable fine finishes with low cutting effort

The uncoated cermet grade NS9530 is formulated as a dedicated finishing grade for steel, providing a sharp cutting edge and low cutting forces that reduce heat and minimise workpiece distortion. This results in consistently improved surface quality on turned components and fewer secondary operations. As an ISO component, the insert supports standardised clamping routines and predictable process behaviour, which helps stabilise cycle times and reduces scrap rates.

Secure fit and straightforward mounting for production reliability

Compatibility with toolholders is defined by form, relief angle, tolerance class, fastening method, size and thickness. The insert’s rhombic shape, 3.97 mm thickness and cylindrical hole with a single‑side countersink (40°–60°) ensure secure locating and repeatable seating in most ISO‑compliant external holders and boring bars. This mechanical reliability reduces index‑up time and makes tool changes predictable in a high‑mix workshop environment.

Small corner radius for controlled finishing passes

With a 0.2 mm corner radius, the insert supports fine finishing passes that preserve geometric accuracy while enhancing visual and tactile surface quality. The small radius helps to avoid chatter in light‑cutting conditions and, combined with the sharp cermet edge, enables low feed, high‑quality cuts on continuous turning operations. Engineers seeking tight tolerances will find this geometry especially useful for specification‑driven production.

Process advantages and application scope

Designed primarily for turning, the insert serves both external and internal operations where a finishing cut is required. The 80° included angle and 7° relief angle contribute to stable cutting forces and consistent chip flow when paired with an appropriate single‑sided chipbreaker. The result is reduced tool‑wear variability and more predictable insert life, which benefits planning for regrind or replacement intervals and supports lean manufacturing goals.

Material suitability and handling recommendations

The grade is optimised for steel work, particularly in continuous cutting and small depths of cut; it is not coated, which enhances edge sharpness for finishing tasks. Select a matching single‑sided chipbreaker and an ISO‑standard holder that accommodates the insert’s form and dimensions to fully exploit the NS9530 characteristics. For best results, use appropriate cutting data for finishing: reduced feeds, moderate spindle speeds and steady coolant or air blow to maintain chip control and surface integrity.

FAQ

What applications suit this insert best?
The CCMT09T302 NS9530 insert is intended for finishing in external and internal turning operations, particularly on steel where a sharp uncoated cermet edge and low cutting forces are required.

Is the insert compatible with standard ISO holders?
Yes. Compatibility depends on holder form, relief angle, tolerance class, fastening and plate thickness; the insert follows ISO geometry and is suitable for ISO‑compliant external holders and boring bars.

What material is the insert made from and which workpieces are recommended?
The insert is made of cemented carbide cermet (uncoated) in grade NS9530, optimised for steel finishing cuts and continuous turning with small depths of cut.
