DCMT 070204 NS9530 — Turning insert, uncoated cermet, Tungaloy

DCMT070204 NS9530 Tungaloy insert for ISO-form turning applications, optimised for finishing cuts on Stahl with a single-sided chipbreaker and a narrow corner radius.

• Uncoated cermet grade NS9530
• Designed for finishing turning
• Rhombic ISO shape 07, 55° cutting angle
• 0.4 mm corner radius, 7° clearance

High-precision finishing with low cutting forces

The NS9530 uncoated cermet grade is developed for finishing cuts on Stahl, delivering a combination of a sharp cutting edge and reduced friction that supports consistently high surface quality. The narrow 0.4 mm corner radius and the geometry designed for continuous cuts reduce vibration and cutting forces, which in turn minimises workpiece distortion and helps achieve reproducible part tolerances. This makes the insert particularly suitable for light- to medium-duty finishing where surface integrity and dimensional accuracy are decisive.

Reliable clamping and straightforward holder compatibility

Designed to ISO plate dimensions, the rhombic 07 format and the central hole ensure compatibility with standard ISO external inserts and boring bars. The plate thickness of 2.38 mm and the cylindrical hole with a one-sided countersink (40°–60°) provide secure seating and repeatable clamping behaviour. Because compatibility depends on form, free angle, tolerance class, fastening method, size and thickness, the standardised geometry simplifies insert selection and shortens setup times in production environments, supporting efficient changeover and lower downtime.

Controlled chip formation and consistent surface integrity

The single-sided chipbreaker combined with the uncoated cermet composition promotes fine, predictable chip formation during finishing passes and small depths of cut. The material pairing—cermet cutting composition on a robust backing—supports a sharp edge that resists adhesion and provides a high-quality surface finish even at continuous cutting conditions. For turning operations where low cutting forces and excellent part appearance are priorities, this solution reduces the need for secondary finishing and enhances process stability.

FAQ

What types of operations is this insert intended for?
The DCMT070204 NS9530 insert is intended for finishing turning operations, offering a sharp edge and low cutting forces suitable for continuous cuts on Stahl.

Is the cutting grade coated or uncoated?
This insert uses an uncoated cermet grade (NS9530), which prioritises edge sharpness and surface finish in finishing applications.

Which holder features are required for correct mounting?
Correct mounting requires an ISO-compatible holder matching the plate form, free angle and thickness; the DCMT070204 uses a cylindrical hole with a one-sided countersink for positive clamping.

What surface quality can be expected with this insert?
When used for the recommended finishing parameters, the NS9530 grade promotes a high surface finish due to its sharp edge and controlled chip formation.

How does the corner radius influence performance?
The 0.4 mm corner radius reduces cutting forces and helps to achieve fine surface results in small-depth finishing cuts while maintaining dimensional accuracy.
