DCGT11T304 NS9530 ISO indexable turning insert — uncoated cermet finish grade | Tungaloy

The DCGT11T304 NS9530 is an ISO‑standard indexable insert for external and internal turning, optimised for fine finishing of steel with low cutting forces and excellent surface quality

• ISO rhombic insert DCGT 11T304 NS9530
• Uncoated cermet for fine finishing
• 0.4 mm corner radius for smooth surfaces
• 7° relief angle for low cutting forces
• Cylindrical hole with 40°–60° countersink

Consistent finishing performance for steel turning

The finishing grade is based on an uncoated cermet formulation, marked NS9530, which provides a balance of sharpness and wear resistance suited to continuous cutting and small depths of cut. The cutting geometry and the 0.4 mm corner radius produce a finer edge contact that lowers cutting forces and reduces workpiece vibration, resulting in a measurable improvement in surface finish. For operations where dimensional repeatability and minimal post‑process smoothing are essential, this insert delivers the required outcome with predictable results.

Secure ISO compatibility and straightforward mounting

Designed to the ISO‑standard geometry DCGT11T304, the insert is compatible with holders that match in form, relief angle, tolerance class, fastening type, size and thickness. The 7° relief angle and 3.97 mm thickness are decisive for stable clamping and reliable cutting line placement. The plate’s rhombic outline and its hole configuration — a cylindrical centre hole with a one‑sided countersink (40°–60°) — simplify location and fastening in standard external holders and boring bars, reducing setup time and enabling consistent assembly across production batches.

Predictable chip control and durable finish life

The single‑sided chipbreaker and the cermet cutting material create a controlled chip formation that suits finishing cuts in steel, maintaining edge integrity under steady feeds. The combination of a sharp, wear‑resistant cutting edge and the single‑sided chipbreaker allows for low cutting forces and minimal flank abrasion, which translates into longer useful life in finishing duties. For non‑specialists: cermet combines ceramic hardness with metallic toughness, delivering good wear resistance while retaining an edge geometry that produces improved surface quality compared with conventional grades.

FAQ

Which materials is this insert intended for?

The DCGT11T304 NS9530 indexable insert is formulated as a finishing grade for steel; the uncoated cermet composition is optimised for low cutting forces and high surface quality in steel turning.

What are the main advantages of the NS9530 uncoated cermet grade?

NS9530 provides a sharp cutting edge with good wear resistance typical of cermet compositions, yielding improved surface finish and stable dimensional results during continuous finishing operations.

How is compatibility with tool holders ensured?

Compatibility is governed by the ISO geometry: form, relief angle, tolerance class, fastening method, size and thickness must match the holder. The DCGT11T304 form, the 7° relief angle and the hole/countersink detail permit reliable clamping in standard external holders and boring bars.

Is the insert suitable for interrupted cuts or roughing?

This grade is optimised for continuous finishing cuts and small depths of cut; interrupted cuts and heavy roughing are not the primary application and may reduce tool life or compromise finish quality.

What assembly and positioning features support repeatability?

The rhombic shape with a central cylindrical hole plus one‑sided countersink (40°–60°) and defined thickness ensure consistent seating and tightening force, which aids repeatable positioning and stable cutting conditions.
