DCMT070202 NS9530 — Turning insert (uncoated cermet, 0.2 mm radius) by Tungaloy

DCMT070202 NS9530 is an ISO-standard rhombic turning insert designed for precision finishing of steel components, offering a sharp cutting edge and stable performance in continuous cut conditions.

• Uncoated cermet finishing grade
• Sharp edge for superior surface finish
• One-sided chipbreaker for continuous cuts
• Rhombic 07 geometry with 55° included angle

Deliver consistent finishing and low cutting forces for steel turning

The insert is developed as a finishing grade for steel, based on an uncoated cermet substrate that prioritises a sharp edge and reduced cutting resistance. These characteristics contribute to low cutting forces, which in turn lower feed-induced vibration and support finer surface finishes during small depth-of-cut operations. The combination of sharp geometry and the small 0.2 mm corner radius enables reliable dimensional control on external and internal profiles while maintaining a high-quality surface without aggressive parameters.

Stable chip control and predictable productivity

A one-sided chipbreaker provides a consistent chip form suited to continuous cuts, improving evacuation and reducing the risk of built-up edge. This stability in chip formation enhances tool life and machining predictability, which is particularly valuable in serial production or when machining long parts. The finishing nature of the grade means process windows are optimised for small feeds and reduced cutting forces, resulting in a balance between surface integrity and productive machining.

ISO compatibility and secure mounting for system flexibility

Manufactured to ISO standards, the insert’s compatibility with holders depends on form, relief angle, tolerance class, fastening method, size and thickness. Key geometry details — rhombic 07 shape, 55° included angle, 7° relief angle and 2.38 mm thickness — support straightforward selection of matching external holders or boring bars. The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) to suit common clamping systems; a complete cutting system therefore comprises an ISO insert, an appropriate external holder or boring bar, a shim/clamping set and replacement screws. If uncertainty arises regarding holder choice or clamping, Metav Werkzeuge’s consultants can advise on the correct combination for the intended turning task.

FAQ

What material is the NS9530 grade optimised for?
The NS9530 grade is a finishing cermet optimised primarily for machining steel, delivering a sharp edge and reduced cutting forces for high surface quality.

Which holder geometry suits this insert?
Compatibility depends on holder form, relief angle, tolerance class and clamping method; the insert’s rhombic 07 shape, 7° relief angle and 2.38 mm thickness are the key parameters for selecting a matching external holder or boring bar.

Is the insert suitable for continuous cuts or interrupted cuts?
The one-sided chipbreaker and the uncoated cermet finishing grade make it particularly well suited to continuous cuts and small depths of cut; interrupted cuts are generally less favourable for this finishing specification.

What is the correct designation and SKU for ordering?
Order as DCMT070202 NS9530; the SKU/reference is 6998468-Tungaloy and the manufacturer article number is 6998468.
