DCGT 11T302 NS9530 Turning Insert — DCGT11T302, uncoated cermet, 7° clearance by Tungaloy

DCGT11T302 NS9530 is a precision ISO turning insert designed for finishing steel in continuous-cut operations, compatible with standard ISO holders when matching form, size and clamping.

• Uncoated cermet for high-quality finishing
• Sharp cutting edge for low cutting forces
• ISO rhombic shape with 55° included angle
• Cylindrical hole with 40°–60° countersink

High-precision finishing with a low-force cutting edge

The insert is supplied in the NS9530 grade, an uncoated cermet developed for fine finishing on steel. The material combination yields a sharp cutting edge and reduced built-up edge, which leads to lower cutting forces and a consistently improved surface finish in continuous, light-cut turning operations. For shops aiming to increase first-pass quality while reducing rework, this geometry and grade support shorter cycle times and predictable results. The product name DCGT11T302 appears on most technical drawings and order references for clear identification.

Predictable mounting and geometry for stable machining

The ISO rhombic format with a 55° included angle and 7° clearance ensures stable engagement and repeatable tool positioning when matched to an appropriate external holder or boring bar. The 0.2 mm corner radius balances edge strength with the fine finish expected from a finishing grade, while the 11 mm size and 3.97 mm thickness provide a compact yet rigid platform. The insert’s cylindrical hole with a single-sided countersink (40°–60°) facilitates secure clamping and straightforward replacement, reducing downtime associated with indexable tooling changes and maintaining consistent cutting geometry across tool life.

Application guidance and process benefits

Designed primarily for turning and specifically for finish passes on steel, the single-sided chipbreaker and cermet composition favour continuous cuts and small depths of cut. This results in excellent surface integrity and minimises the need for secondary polishing. In production environments where surface finish and component conformity are critical, the combination of a dedicated finishing grade and robust ISO compatibility translates into improved process reliability and repeatable part quality. When selecting a holder, ensure form, rake clearance, tolerance class, fastening method, size and thickness match the insert to maintain the advertised performance.

FAQ

What materials is this insert best suited for?
The DCGT11T302 NS9530 Tungaloy turning insert is optimised for finishing operations on steel, where the uncoated cermet grade provides a sharp edge and high surface quality.

How does the 0.2 mm corner radius affect performance?
A 0.2 mm corner radius provides a balance between edge strength and fine surface finish; with the NS9530 grade, this radius supports controlled chip formation and consistent results in finish passes.

Which holder features must be matched to this ISO insert?
Compatibility requires matching form, clearance angle, tolerance class, fastening method, size and thickness; the rhombic shape and 55° included angle must be supported by the chosen external holder or boring bar.

Is this insert suitable for interrupted cuts?
The grade and geometry are optimised for continuous cutting and small depths of cut; interrupted cuts may reduce tool life and are not the primary application for this finishing insert.

What fastening detail does the insert have for mounting?
The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) to ensure secure clamping in compatible ISO clamping systems.
