DPMT 11T304 NS9530 — Turning insert (uncoated cermet), Tungaloy

DPMT11T304 NS9530 is an ISO rhombic turning insert designed for finishing steel with a sharp cutting edge and low cutting forces

• ISO‑standard rhombic insert
• NS9530 uncoated cermet grade
• Sharp edge for superior surface finish
• 0.4 mm nose radius for fine finishing

Consistent finishing for steel turning operations

The NS9530 uncoated cermet grade is formulated for finishing operations on steel, delivering a sharp cutting edge that reduces cutting forces and enhances the final surface quality. Cermet combines ceramic and metallic properties to resist abrasion while preserving edge geometry; this results in stable performance during continuous feeds and when taking small depths of cut. The design reduces the need for additional polishing, shortening downstream processing and improving throughput.

Secure mounting and predictable geometry for repeatable results

The ISO‑compliant rhombic form and 11° clearance ensure consistent seating and predictable tool engagement across standard holders. The insert features a through‑hole with a cylindrical bore and a single‑side countersink (40°–60°) for positive clamping and repeatable positioning. The nominal geometry, including the 55° main cutting angle, supports stable chip control and dimensional consistency, so compatibility with the correct holder—considering form, clearance, tolerance class, clamping and thickness—becomes straightforward.

Productivity gains through reduced secondary work

As a finishing grade, this insert is optimised to deliver high surface quality with minimal passes. The 0.4 mm radius promotes fine profile accuracy while the single-sided chipbreaker helps form short, controllable chips under continuous cutting conditions. Together, these features contribute to lower cycle times and reduced rework, offering an efficient balance of precision and economy for medium‑volume production runs.

Choosing the right variant and handling tips

Select the matching chipbreaker and NS9530 grade when machining steels where a fine surface and low cutting forces are priorities. The insert thickness (3.97 mm) and insert size (11) require corresponding holder dimensions; ensure the clamping hardware and screws match the insert’s countersink and hole style. Handles and toolblocks rated for the insert geometry will preserve edge life; replace screws and clamps that show wear to maintain repeatability and surface integrity.

FAQ

Which materials is this insert best suited for? The DPMT11T304 NS9530 insert is primarily intended for finishing operations on steel, where its uncoated cermet composition provides a fine surface and low cutting forces.

What cutting conditions suit this grade? NS9530 performs best with continuous cutting and small depths of cut, offering stable edge life and high surface quality under consistent feed conditions.

How is the insert secured to the holder? The insert uses a cylindrical hole with a single-sided countersink (40°–60°) for positive clamping; correct holder selection and matching screws ensure repeatable seating.

What surface finish can be expected? Thanks to the sharp edge and low cutting forces of the NS9530 grade, a high surface finish is achievable in a single finishing pass for many steels.

Which chipbreaker and operations are supported? This configuration features a one-sided chipbreaker and is suitable for external and internal turning where finishing and chip control are required.
