DCGT 11T302 NS9530 ISO rhombic turning insert for finishing — Tungaloy

The DCGT11T302 NS9530 is an ISO‑standard rhombic turning insert designed for finishing operations on steel, offering a sharp cermet grade for low cutting forces and superior surface quality.

• Cermet finishing grade NS9530
• Sharp cutting edge for fine finishes
• Low cutting forces for continuous cuts
• ISO rhombic 11 with 7° clearance

High‑precision finishing with a cermet grade built for steel

The combination of uncoated cermet and the NS9530 grade makes this insert ideal for delicate finishing passes on steel where a high surface finish is essential. The thin, sharp edge and optimised geometry reduce cutting forces, which is particularly beneficial for small depths of cut and continuous turning operations. For workshops seeking a reliable finishing solution, the cemented carbide substrate and cermet chemistry provide stable cutting behaviour and predictable surface results across batch production.

System compatibility and secure clamping for dependable results

Designed as an ISO‑type insert, compatibility with a holder is determined by form, clearance angle, tolerance class, fixation, size and thickness. The rhombic form with a 7° clearance and an included 0.2 mm corner radius supports precision positioning and repeatable part quality. The insert is supplied as part of a system comprising a suitable outer holder or boring bar, shim/clamping set and replacement screws; matching these elements ensures secure clamping and avoids chatter. For process planning, specify the ISO code and size so that the appropriate holder geometry can be selected with confidence.

Productivity benefits and application guidance for production use

As a finishing grade intended for continuous cutting and small feed/stroke values, the insert reduces rework and accelerates throughput by producing parts closer to final tolerance on the first pass. The one‑sided chipbreaker geometry helps form consistent chips when machining steel in steady conditions, supporting predictable tool life and surface integrity. For shops aiming to improve cycle times without sacrificing finish, this insert delivers a pragmatic balance of toughness and edge sharpness suitable for series production and precision components.

FAQ

What applications is this insert best suited for?
The DCGT11T302 NS9530 insert is optimised for finishing on steel, especially continuous turning with small depths of cut where a high surface finish is required.

Is the insert suitable for interrupted cuts?
Given the uncoated cermet composition and its sharp edge, the DCGT11T302 performs best in continuous cuts; interrupted cuts may reduce edge life and are not the primary application.

How does the one‑sided chipbreaker affect machining?
The one‑sided chipbreaker on this grade promotes consistent chip formation during finishing passes, supporting stable cutting forces and improved surface quality with the NS9530 chemistry.

What must be considered when matching a holder to this insert?
Compatibility depends on insert form, clearance angle, tolerance class, fixation method, size and thickness; ensure the holder matches the ISO designation and the 11 size to guarantee correct seating and clamping.

Can this insert be used on materials other than steel?
This grade is specified for finishing steel; performance on other materials is not indicated in the available data and should be validated before production use.
