DCMT 070208 NS9530 — ISO turning insert for finishing, Tungaloy

The DCMT 070208 NS9530 is an ISO rhombic insert engineered for precision external and internal turning, offering a cermet finishing grade optimised for continuous cuts.

• ISO rhombic 07 geometry
• Uncoated cermet NS9530 grade
• 0.8 mm corner radius
• Cylindrical hole with countersink

Predictable surface quality from a cermet finishing grade

The NS9530 uncoated cermet grade delivers a sharp cutting edge and low cutting forces, which together produce a high surface finish in finishing operations. The DCMT 070208 NS9530 insert is intended for continuous turning with small depths of cut, where consistent edge line and chip control reduce rework and downstream polishing. The material properties of the cermet contribute to stable cutting temperatures and improved dimensional consistency, supporting a measurable reduction in secondary operations and a more reliable production flow.

Secure seating and ISO-based compatibility for reliable clamping

As an ISO indexable insert in rhombic format, compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness. This insert has a 2.38 mm thickness, a 7° relief angle and a 0.8 mm corner radius, plus a cylindrical hole with a one-sided countersink (40°–60°) for positive seating. The single-sided chipbreaker supports predictable chip formation under steady feeds. These features combine to improve tool stability, reduce vibration and deliver repeatable clamping behaviour when matched with a suitable external holder, thereby lowering scrap rates and increasing throughput.

Practical efficiency for steel finishing applications

This finishing grade is formulated specifically for machining steel, providing sharpness and longevity for continuous finishing passes. The uncoated cermet composition emphasises surface quality and dimensional accuracy rather than aggressive stock removal, making it ideal where finish and tolerance are priorities. Operational benefits include stable chip formation, reduced cutting forces and a tendency toward consistent tool life when operated within recommended small depths of cut. For production planning, the insert supports streamlined processes and fewer adjustments between batches, contributing to overall shop-floor efficiency and predictable cycle times. Technical queries may be directed to Metav Werkzeuge specialists for help selecting the correct chipbreaker and holder combination.

FAQ

Is the insert compatible with standard DCMT holders?
The DCMT 070208 NS9530 insert follows ISO indexing and is compatible with holders prepared for DCMT 07 geometry when form, relief angle, tolerance class, fastening, size and thickness are matched.

Which materials is this grade suitable for?
The NS9530 uncoated cermet grade is optimised for finishing steel, providing a sharp edge and low cutting forces for high surface quality in continuous turning.

What are the key dimensions to check when selecting a holder?
Confirm the 2.38 mm thickness, 07 size, 7° relief angle and the presence of a cylindrical hole with a one-sided countersink to ensure correct seating and clamping for this insert.

Can the insert be used for internal turning as well as external turning?
Yes; the insert is suitable for both external and internal turning when used with an appropriate holder and when cutting parameters are adapted for internal operations.

How does the one-sided chipbreaker affect machining?
The one-sided chipbreaker on this insert promotes controlled chip formation in finishing passes, supporting stable cutting and consistent surface quality for the DCMT 070208 NS9530.
