Consistent finishing quality for steel components

The NS9530 cermet finishing grade is formulated to deliver a sharp cutting edge and low cutting forces, which together enable superior surface finishes on steel workpieces. As an uncoated cermet insert, it minimises built-up edge during continuous cuts and short, precise engagements, reducing the need for secondary operations. The combination of a finely graded substrate and a defined nose geometry ensures repeatable results across batch runs, making the insert particularly suitable for shops prioritising surface integrity and dimensional stability.

Predictable chip control and secure clamping for longer productive runs

A double-sided chipbreaker and a cylindrical hole contribute to consistent chip formation and secure seat fixation in the toolholder. The chipbreaker is optimised for small depths of cut and continuous turning, promoting steady chip evacuation and decreasing the risk of irregular chip build-up. Secure clamping, aided by the through-hole, reduces vibration and maintains cutting-edge position, which in turn supports tool life and process reliability during medium- to long-length production runs.

Simple integration into ISO toolholder systems with clear dimensions

The insert follows ISO form conventions for rhombic turning inserts and is compatible with ISO-style holders when the holder’s form, clearance angle, tolerance class, fastening and size match the insert specification. Key dimensions include an inscribed circle of 15 mm, a thickness of 4.76 mm, a nose radius of 0.4 mm and a lead angle of 55° with a 0° rake/clearance. These defined figures support straightforward setup and predictable cutting geometry when selecting or verifying a suitable external or internal turning holder.

Who benefits and typical applications in production

Job shops and production departments performing finishing passes on steel components will find the combination of NS9530 grade and the rhombic insert form advantageous for precision turning tasks. The insert is geared towards external and internal finishing where surface quality and low cutting forces are priorities. For operations that require tight tolerances and consistent surface texture, the uncoated cermet insert provides a balance of sharpness and wear resistance, reducing rework and supporting efficient throughput.

FAQ

Which materials is this insert best suited for?
The DNMG150404 NS9530 is an uncoated cermet finishing grade optimised for steel, delivering low cutting forces and excellent surface finish for finishing operations.

Can the insert be used for internal as well as external turning?
Yes; the DNMG150404 geometry and the double-sided chipbreaker support both external and internal turning when paired with a compatible holder and correct mounting.

What are the key dimensions to check before fitting the insert?
Confirm the inscribed circle (15 mm), thickness (4.76 mm), nose radius (0.4 mm) and the 55° lead angle, and ensure the holder accepts a rhombic insert with a cylindrical locating hole.

Is the cutting material coated?
No, the NS9530 grade is an uncoated cermet developed specifically for finishing with a sharp edge and reduced cutting forces.

How does the chipbreaker affect machining performance?
The double-sided chipbreaker is designed for continuous cuts and small depths of cut, promoting stable chip formation and improving surface quality during finishing.
