CCMT09T304 NS9530 Tungaloy turning insert — ISO rhombic format, uncoated cermet, 0.4 mm radius

A CCMT09T304-format indexable turning insert by Tungaloy, designed for fine finishing in turning operations and compatibility with standard ISO toolholders.

• CCMT09T304 format for ISO toolholders
• NS9530 uncoated cermet grade for fine finishing
• 0.4 mm corner radius for precise profiles
• Cylindrical hole with single countersink 40°–60°

Precision finishing for steels with low cutting forces

The CCMT09T304 NS9530 insert is manufactured as an uncoated cermet grade optimised for finishing cuts where a fine surface finish and low cutting forces are priorities. The NS9530 composition delivers a sharp edge geometry, reduced built-up edge tendency and consistent edge integrity during continuous, light-depth passes. With a 0.4 mm corner radius, the insert supports precise profile control and predictable corner behaviour, which helps to maintain dimensional accuracy and reduces the need for secondary finishing. The result is a combination of improved surface quality and extended effective tool life in stable turning conditions.

Secure clamping and ISO compatibility for consistent results

Designed to the ISO indexable insert system, this rhombic-shaped insert features an 80° included angle and a 7° relief (clearance) angle. Compatibility with a holder is determined by the insert form, relief angle, tolerance class, method of attachment, size and thickness. The ISO conformity simplifies replacement and inventory management across a production facility. The cylindrical hole with a single countersink (40°–60°) ensures a reliable locating and clamping interface; when paired with a correctly specified external holder or boring bar and appropriate shim/fastening set, the assembly minimises vibration and contributes to reproducible cutting conditions.

Chip control and application guidance for continuous turning

This insert is supplied with a one-sided chipbreaker, intended for continuous cuts and small depths of cut typical of finishing operations. Select the chipbreaker and grade combination according to workpiece material and machining stability: the NS9530 finishing grade is particularly suitable for steel where a sharp cutting edge and low cutting forces are required. The insert’s geometry and single-sided chip control promote smooth chip flow and reduce intermittent loading on the cutting edge, which is beneficial in automated or lights-out production runs. For varied production requirements, pairing the insert with holders engineered for stiffness will enhance productivity and surface integrity.

FAQ

What materials is this insert suitable for?
The NS9530 finishing grade is specified for machining steel and is provided as an uncoated cermet to deliver sharp-edge performance and good surface finish when the CCMT09T304 insert is used in turning operations.

How does the 0.4 mm corner radius affect part quality?
A 0.4 mm corner radius offers a balance between edge strength and profile precision; it helps achieve consistent corner geometry and a high-quality surface finish on turned components when light finishing passes are used.

Is the CCMT09T304 compatible with standard ISO holders?
Yes. The CCMT09T304 format conforms to ISO indexable insert standards; compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness, so matching those parameters ensures secure clamping and repeatable performance.

What type of chip control does the insert provide?
The plate is supplied with a one-sided chipbreaker designed for continuous cutting and small depths of cut typical of finishing operations, promoting stable chip flow and reduced edge loading.

Can this insert be used for internal turning?
Yes. The geometry and chip control of the CCMT09T304 make it suitable for both external and internal turning applications when mounted in an appropriate boring bar or holder that provides sufficient rigidity.
