DNMG 150408 NS9530 Tungaloy Turning Insert — ISO rhombic insert for finishing

The DNMG 150408 NS9530 Tungaloy Turning Insert is an ISO‑standard rhombic indexable insert engineered for finishing operations in external and internal turning of steel.

• Sharp cermet grade NS9530 for fine finishing
• Low cutting forces for stable continuous cuts
• ISO DNMG150408 rhombic insert, 55° lead angle
• Cylindrical hole for secure clamping

Consistent surface quality through sharp cermet cutting geometry

The uncoated cermet grade NS9530 is formulated for finishing of steel, offering a very sharp cutting edge that reduces ploughing and enables a superior surface finish in light cuts. As a finishing grade, the material provides low cutting forces and stable metal removal during continuous cuts and small depths of cut. The combination of sharp geometry and the fine grain of the insert material helps to achieve reproducible surface roughness values while keeping thermally induced edge dulling to a minimum.

Reliable fit and repeatable clamping for process stability

Compatibility with holders is defined by form, clearance angle, tolerance class, fastening, size and thickness; the ISO DNMG150408 format guarantees interchangeability across standard turning systems. The rhombic shape with a cylindrical hole ensures secure axial and radial location, while the 55° lead angle balances accessibility and strength. With an insert thickness of 4.76 mm and a nose radius of 0.8 mm, the geometry supports precise profiling and predictable deflection margins for slender setups.

Productivity benefits from chip control and predictable behaviour

The double‑sided chipbreaker design promotes controlled chip formation in finishing cuts, reducing the risk of long, entangling swarf and helping to maintain uninterrupted machining cycles. Because the grade is uncoated, the initial sharpness of the cutting edge is maximised, which translates into lower feed force requirements and reduced machine vibration for delicate operations. These process attributes contribute to shorter cycle times on finishing passes and consistent part quality in serial production.

Practical system guidance and suited applications

Designed for integration in a standard turning system—indexable insert, matched external holder or boring bar, backing/clamp set and replacement screws—this insert is best applied where a fine surface finish on steel is the priority. Select the double‑sided chipbreaker and the NS9530 finishing grade when stability is assured and material removal is light; for roughing or interrupted cuts, choose a more robust grade or a dedicated chipbreaker variant. The rhombic profile and 55° lead angle permit efficient approach angles for both external profiling and internal turning operations.

FAQ

What materials is this insert optimised for?
The DNMG 150408 NS9530 is optimised for finishing operations in steel, where sharp edge geometry and low cutting forces are required to achieve high surface quality.

Is the insert indexable on both sides?
Yes, the insert features a double‑sided chipbreaker design that allows indexing to the next cutting edge, extending usable life before replacement is required.

Which holders are compatible with this ISO format?
Standard ISO‑compatible DNMG holders and boring bars that accept DNMG150408 inserts will accommodate this format; compatibility depends on form, clearance angle and clamp arrangement.

What are the key geometry values to consider for setup?
Important geometry values are the nose radius of 0.8 mm, the insert thickness of 4.76 mm and the 55° lead angle, which together influence approach angle, deflection and achievable surface finish.

How does the uncoated cermet grade affect performance?
The uncoated cermet grade NS9530 provides a very sharp initial edge and low cutting forces, making it well suited to continuous finishing cuts and small depths of cut where surface quality is critical.
