DPMT DPMT11T308 NS9530 — Indexable Turning Insert for Turning (Tungaloy)

DPMT11T308 NS9530 is an ISO‑format rhombic insert optimised for precision external and internal turning, offering a sharp cutting edge and low cutting forces for excellent surface quality

• Uncoated cermet NS9530 for superior finish
• Sharp cutting edge for low cutting forces
• ISO rhombic form DPMT with 11° relief
• Cylindrical hole with 40°–60° countersink

High‑quality finish and reduced rework through grade design

The NS9530 grade is an uncoated cermet developed for finishing operations in steel, delivering a sharp cutting edge that reduces cutting forces and limits workpiece deformation. This leads to a measurable improvement in surface finish, shorter downstream finishing cycles and fewer rejected parts. For operations with continuous cutting and small depths of cut, the grade supports consistent dimensional accuracy and helps maintain stable process windows.

Consistent clamping and compatibility with ISO holders

Built to the ISO DPMT series, the insert's rhombic geometry and standard sizing ensure compatibility with a wide range of external holders and boring bars; holder fit depends on form, relief angle, tolerance class, fixing method, size and thickness. The insert features an 11° relief, a corner radius of 0.8 mm, and a plate thickness of 3.97 mm, enabling predictable seat location and repeatable set‑up when replacing inserts, which reduces machine downtime and simplifies tool inventory management.

Improved chip control and process stability

Equipped with a single‑side chipbreaker, the design supports controlled chip formation in finishing cuts, minimising the risk of entangling chips and improving evacuation. Selecting the appropriate chipbreaker and the NS9530 grade for the workpiece material and process stability yields stable cutting conditions and consistent edge integrity. These factors contribute to predictable cycle times and allow planners to model cost‑per‑part with greater confidence.

System‑oriented setup for efficient tool changes

The insert is supplied as part of an ISO‑based system: the insert, a matching external holder or boring bar, a shim/clamping set and spare screws form the working assembly. This modular approach simplifies maintenance and tool change routines, supports fast replacement, and keeps fixtures and countersinks aligned. The product is identified by manufacturer SKU TUN6951258, enabling straightforward procurement and traceability within production environments.

FAQ

What materials is this insert intended for?
The NS9530 grade is designed for finishing in steel; the insert provides low cutting forces and a sharp cutting edge suited to continuous finishing cuts on steel components.

How does the DPMT geometry affect holder compatibility?
ISO DPMT format determines compatibility by form, relief angle, tolerance, fixing method, size and thickness; matching these parameters with the chosen holder ensures correct fit and repeatable positioning.

Which chip control is provided by this insert?
The insert features a single‑side chipbreaker that promotes stable chip formation in finishing operations, improving evacuation and reducing the chance of chip interference.

What are the key dimensions to check before ordering?
Verify the corner radius (0.8 mm), plate thickness (3.97 mm), relief angle (11°) and plate size (11 mm) against the holder specifications to ensure proper seating and clamping.

Can this insert be used for both internal and external turning?
Yes, the ISO‑format rhombic geometry and the uncoated cermet NS9530 grade make it suitable for both external and internal finishing applications where small depths of cut are required.
