CCMT09T308 NS9530 Tungaloy indexable turning insert (uncoated cermet, 7° relief)

The CCMT09T308 NS9530 Tungaloy is an ISO-standard rhombic indexable insert designed for finishing turning operations on steel.

• Uncoated cermet grade NS9530 for fine finishing
• Rhombic CCMT form, 0.8 mm nose radius
• 7° relief angle, 80° included angle
• Cylindrical hole with one-sided countersink

Achieve superior surface finish with low cutting forces

The uncoated cermet grade NS9530 is engineered for finishing applications where surface integrity and dimensional accuracy matter. With a sharp cutting edge and low built-in cutting forces, the insert reduces burr formation and supports extended tool life under continuous cutting conditions. This combination results in a reliably smooth surface without resorting to aggressive machining parameters, making it particularly suited to fine external and internal turning of steel components where a high-quality finish is the primary requirement.

Stable performance for continuous and light-removed cuts

Designed for continuous cutting and small depths of cut, the insert delivers consistent performance when paired with appropriate holder rigidity and cutting data. The one-sided chipbreaker assists chip control in stable setups, while the cermet substrate maintains edge integrity during prolonged finishing cycles. The geometry promotes low vibration susceptibility, so productivity improves through fewer rework cycles and reduced tool-change frequency — a rational efficiency gain for production-oriented workshops.

ISO compatibility and mounting details for predictable setup

Compatibility with standard toolholders depends on form, relief angle, tolerance class, fastening method, size and thickness. The insert follows ISO CCMT geometry: rhombic form, size 09, nose radius 0.8 mm, thickness 3.97 mm and an included angle of 80°. The fixing hole is with a cylindrical hole and a one-sided countersink (40°–60°), so secure clamping and correct seat alignment in the matching holder are essential for repeatable results. These measurable parameters simplify tool selection and help avoid trial-and-error in the workshop.

When this grade is the preferred choice

Select this indexable insert for finishing passes where surface finish and low cutting forces are priorities, particularly in steady-state turning of steel with small feed and depth settings. The combination of NS9530 composition and CCMT geometry offers a pragmatic balance between finish quality and tool life. For applications with interrupted cuts or unstable setups, consider a grade and chipbreaker tailored to those conditions; Metav Werkzeuge’s technical advisers can help match toolholder and cutting data to the workpiece and machine dynamics.

FAQ

Which materials is this insert suitable for?
The NS9530 uncoated cermet grade is intended primarily for finishing steel; the insert’s low cutting-force behaviour supports fine surface results in continuous turning operations.

How does the CCMT geometry affect holder compatibility?
Holder compatibility is determined by the CCMT form, relief angle, tolerance and fastening dimensions; the CCMT09T308 format aligns with ISO-standard holders when the seat and clamp correspond to the insert’s size and thickness.

What surface quality can be expected with a 0.8 mm nose radius?
A 0.8 mm nose radius provides a favourable trade-off between surface finish and strength for finishing cuts, yielding smooth part faces while keeping cutting forces low.

Is the insert coated?
The insert is an uncoated cermet (NS9530), optimised for sharp-edge finishing on steel rather than coated wear resistance for roughing operations.

What chip control does the insert provide?
This variant features a one-sided chipbreaker, offering controlled chip formation in stable cutting conditions; selection of chipbreaker and cutting data should match workpiece material and machine rigidity.
