DCGT 11T304 NS9530 — ISO rhombic turning insert, uncoated cermet, Tungaloy

The DCGT11T304 NS9530 is an ISO‑standard rhombic turning insert engineered for fine finishing of steel components in continuous cuts and small depths of cut.

• ISO rhombic geometry for stable indexing
• Sharp NS9530 uncoated cermet for fine finishing
• 0.4 mm corner radius for precise contours
• Central hole with cylindrical seat and countersink

Delivering consistent fine finishing with low cutting forces

The uncoated cermet grade NS9530 is formulated to produce a very sharp cutting edge and reduced built‑up edge, which results in lower cutting forces and improved surface quality when turning steel. For shops seeking predictable part finish and dimensional stability, this grade supports continuous cutting strategies and small depth‑of‑cut machining where surface integrity is critical. The rhombic insert geometry and the modest 0.4 mm corner radius ensure accurate contouring on external and internal profiles while maintaining consistent tool life in routine finishing operations.

Stable chip control and secure clamping for productive turning

A one‑sided chipbreaker combined with the central cylindrical hole and one‑sided countersink (40°–60°) provides repeatable chip flow and secure mechanical clamping in compatible holders. The insert’s 7° clearance angle reduces rubbing at the flank and helps to maintain cutting efficiency across a range of feed rates. Together, these details enable predictable chip evacuation and minimise the risk of unexpected edge damage, enhancing process stability in production runs and reducing downtime for edge changes.

Easy integration into ISO‑compliant tool systems

Designed to the ISO turning insert family, the geometry, thickness and hole configuration of this series ensure broad compatibility with standard external holders and boring bars when matched by form, clearance angle and tolerance class. The insert thickness of 3.97 mm and the inscribed circle size 11 make setup straightforward for existing toolholders that accept the DCGT form. Where grading and chip control are decisive, selecting the matching holder and clamping kit ensures the insert performs to its intended specification without adaptation.

Practical benefits for workshop productivity and quality

Using a grade focused on finishing translates into measurable shop benefits: fewer rework cycles due to improved surface finish, reduced force‑induced distortion on thin‑walled parts, and extended intervals between tool edge changes when conditions align with the grade’s strengths. The DCGT geometry with 55° insert angle also supports stable engagement on shoulders and taper features. For operations prioritising repeatability and surface integrity in steel turning, this insert offers a balanced compromise between sharp cutting performance and dependable handling under continuous feed conditions.
