DNMG 150408 NS9530 Tungaloy ISO turning insert for finishing

The DNMG 150408 NS9530 is an ISO-standard rhombic turning insert intended for external and internal turning, optimised for finishing cuts in steel and continuous-cut operations

• ISO rhombic DNMG 150408 geometry
• NS9530 uncoated cermet finishing grade
• Low cutting forces and sharp cutting edge
• Double-sided chipbreaker, cylindrical hole

High-quality finishing with reduced cutting forces

The NS9530 uncoated cermet grade provides a clearly perceptible benefit for finishing operations: a sharp cutting edge that lowers cutting forces and produces a high surface finish even at small depths of cut. This advantage translates into fewer secondary passes and less need for manual rework, improving overall process efficiency. The morphology of the grade is geared towards continuous cutting, so stability and surface quality remain consistent during long running times.

Dependable ISO compatibility for flexible tool choices

The ISO-designation ensures the insert fits standard toolholders when the geometric attributes match. Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness, so the component is suitable for common clamping systems in modern turning applications. The standardised format simplifies tool management in the workshop and enables rapid replacement, reducing setup times and supporting repeatable machining results.

Consistent chip control and secure mounting for uptime

Equipped with a double-sided chipbreaker and a cylindrical centre hole, this rhombic insert promotes controlled chip formation and easy indexing. The 0.8 mm corner radius and 0° relief angle contribute to a predictable contact geometry that supports a stable cutting process and reduces the risk of vibration. Secure clamping via the cylindrical hole and standard fastening elements reduces the likelihood of insert movement, helping to maintain surface quality and extend productive cutting time between tool changes.

Practical advantages in the workshop and recommended use

Designed as a finishing grade for steel, the insert performs best with small feed rates and continuous cuts where high surface integrity is required. The simple system setup — insert, matching outer holder or boring bar, backing/clamping set and spare screws — permits quick replacement and consistent repeatability across batches. Where higher chipload or interrupted cuts are expected, choosing a different breaker or grade is advised; for fine finishing, the combination of geometry and grade delivers measurable improvements in output consistency and part appearance.
