DCMT070202 NS9530 indexable turning insert — uncoated cermet, fine finishing, Tungaloy

DCMT070202 NS9530 is an ISO-format indexable insert designed for precision external and internal turning, optimised for fine finishing on steel with continuous cuts and small depths of cut.

• Uncoated cermet grade NS9530 for fine finishing
• Sharp cutting edge for low cutting forces
• ISO DCMT geometry for wide holder compatibility
• One-sided chipbreaker optimised for continuous cuts

Achieve consistent high-quality surfaces with low cutting effort

The uncoated NS9530 cermet grade delivers a sharp cutting edge that reduces cutting forces and enhances surface quality on steels. This characteristic is especially valuable in finishing passes where high surface finish is required and where small depths of cut are common. The insert’s geometry supports steady cutting behaviour in continuous operations, helping to maintain part tolerances and reduce downstream polishing or grinding effort.

Secure fit and predictable performance in ISO systems

The ISO DCMT form follows standard dimensions and fixation criteria, so compatibility with authorised external holders and boring bars is straightforward. The insert’s relief angle of 7° and nominal approach angle of 55° are designed to match common clamp and screw patterns; compatibility depends on holder form, angle and tolerance class. This standardisation reduces set-up time and supports repeatable results across batch runs.

Optimised chip control and fine-detail finishing

A one-sided chipbreaker directs chips away from the cutting zone, supporting uninterrupted cutting in continuous feeds and minimising re-cutting of swarf. The small corner radius of 0.2 mm promotes fine edge definition, producing sharp contours and improving finish on turned components. These attributes make the insert suitable for external and internal finishing tasks where dimensional accuracy and visual quality are priorities.

Practical guidance for selection and use

Select the uncoated cermet grade when priority is finishing on steels with stable cutting conditions and modest material removal. The DCMT070202 geometry and the insert’s standardised hole and countersink ensure secure clamping; use an appropriate holder with matching form and tolerance class. If uncertainty remains about the best holder or cutting parameters for a specific component, additional process data and tailored recommendations are available.

FAQ

What materials is this insert suited for?
The DCMT070202 NS9530 insert is formulated as an uncoated cermet for finishing operations on steel and is optimised for continuous cutting and small depths of cut.

How does the 0.2 mm corner radius affect machining?
A 0.2 mm radius provides a fine cutting edge that improves dimensional accuracy and surface quality during finishing passes with the DCMT070202 geometry.

Is the insert compatible with standard ISO holders?
Yes. The insert follows ISO DCMT dimensions and the standard hole/countersink arrangement, allowing secure fixation in holders designed for DCMT inserts.

What chip control can be expected from this grade?
The one-sided chipbreaker is designed to direct chips away from the cutting zone, supporting uninterrupted continuous cuts and reducing the risk of chip re-cutting.

Can this insert be used for roughing?
The NS9530 uncoated cermet is primarily a finishing grade; for heavy roughing it is preferable to select a grade designed for higher cutting forces.
