DCMT070204 NS9530 indexable turning insert — uncoated cermet, 7° clearance (Tungaloy)

A DCMT070204 NS9530 indexable turning insert designed for fine finishing of steel in external and internal turning, offering a sharp cutting edge and low cutting forces.

• Uncoated cermet for fine finishing
• Low cutting forces, sharp cutting edge
• ISO rhombic 07 shape, 7° clearance
• Cylindrical hole with 40°–60° countersink

Superior surface quality for finishing operations

The NS9530 grade is an uncoated cermet intended as a finishing mix for steel, providing a sharp cutting edge and reduced built-up edge compared with many coated grades. This results in a better surface finish under continuous cutting conditions and when using small depths of cut. The 0.4 mm corner radius supports fine profile definition and smooth transitions, while the inherent hardness and edge stability of cermet help to keep cutting forces low, which in turn reduces vibration and the risk of chatter during light finishing passes.

ISO compatibility and secure seating for predictable results

Designed to the ISO designation DCMT070204, the insert uses a rhombic (07) geometry and a nominal engagement angle of 55°, ensuring broad compatibility with standard ISO turning holders. The 2.38 mm thickness and the 7° clearance are decisive for correct seating and cutting geometry; compatibility to a given holder depends on form, clearance angle, tolerance class, fastening, size and thickness. The insert is supplied with a cylindrical hole and a single-side countersink (40°–60°) for secure mechanical location and positive clamping in a suitable pocket with the correct clamping set and screw.

Machining benefits and typical applications

As a finishing grade for steel, this insert excels on continuous cuts and small feed-depth combinations where a fine surface is the primary objective. The single-sided chipbreaker supports predictable chip formation for finishing passes and contributes to stability in many set-ups. Because the grade aims to minimise plastic deformation at the cutting edge, it is particularly suitable where low cutting forces and a high surface integrity are required, for both external and internal turning tasks that prioritise dimensional control and surface quality.

Practical selection and handling guidance

Select the NS9530 finishing grade when the priority is surface quality rather than heavy material removal. Match the chipbreaker style to the workpiece material and the clamping stability of the set-up; the single-sided breaker is optimised for finishing and steady feeds. Ensure the insert pocket is clean, the seating surface undamaged and the correct screw and clamping set are used to achieve repeatable positional accuracy. Regular inspection of the cutting edge and adherence to recommended torque values will help maintain consistent results across production batches.

FAQ

Which materials is this insert intended for?
The DCMT070204 NS9530 insert is a finishing grade specifically formulated for steel, providing a sharp edge and low cutting forces for improved surface integrity.

What chip control can be expected from this geometry?
The single-sided chipbreaker on this Tungaloy insert offers controlled chip formation suited to finishing passes and steady feeds, improving stability during light cuts.

How is the insert secured in the holder?
The insert uses a cylindrical hole with a single-side countersink (40°–60°) and is clamped into an ISO-compatible pocket; correct clamping sets and screws must be used to ensure reliable seating of the DCMT070204 NS9530.

Which holder characteristics ensure compatibility?
Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; the rhombic 07 format and 2.38 mm thickness require an ISO holder pocket matching these dimensions.

What does the 0.4 mm corner radius affect in practice?
A 0.4 mm corner radius offers a balance between fine surface finish and edge strength, enabling precise profile definition on finishing passes with less tendency for edge breakdown.
