DPMT11T308 11T308 NS9530 DPMT turning insert — uncoated cermet finishing grade by Tungaloy, 11° relief, rhombic form

DPMT11T308 NS9530 Tungaloy-Wendeplatte is an ISO-format indexable insert designed for precision external and internal turning where surface finish and low cutting forces are critical

• ISO rhombic insert DPMT11T308
• Cermet NS9530 for fine finishing
• 11° relief, 55° included angle
• Cylindrical hole with single‑side countersink

Deliver consistently fine surface finishes with minimal cutting forces

The uncoated cermet construction of this finishing grade is engineered to deliver a sharp cutting edge and low cutting forces, which directly reduces workpiece distortion during light finishing passes. For turning tasks that prioritise surface quality—especially continuous cuts with small depths of cut—this insert provides a measurable benefit: improved first-pass finish and reduced need for secondary operations. The material choice and edge form make the insert particularly suited to finishing operations on steel, where consistent geometry and a refined surface are central to downstream processes.

Secure fit and ISO compatibility simplify tool setup

Designed to the ISO standard for turning inserts, the geometry ensures reliable seating and repeatable positioning in compatible toolholders. Compatibility is defined by shape, relief angle, tolerance class, clamping style, size and thickness; this insert features a rhombic form, 11° relief and a thickness of 3.97 mm, together enabling secure clamping and predictable cutting behaviour. The central cylindrical hole with a one‑sided countersink (40°–60°) provides standard fixation while supporting easy rotation when reindexing, helping to maintain production uptime and reduce handling complexity.

Apply the right chipbreaker and cutting conditions for the best outcome

The tooling system works as a whole: choose the chipbreaker and grade that match component material, machining type and machine/tool stability. This particular insert comes with a single-sided chipbreaker intended for finishing; pairing it with a rigid holder and stable setup yields the best results. For finishing of steel components, small feeds and shallow depths of cut are recommended to exploit the low cutting forces and sharp edge geometry, which together enhance surface quality and dimensional accuracy without excessive tool wear.

Practical handling and application notes for longer service life

Although optimised for finishing, the insert benefits from correct handling and mounting: ensure the mating holder and shim/clamp are free from damage and that tightening torque follows the holder supplier’s guidance to preserve seating and repeatability. The 0.8 mm corner radius is suited to fine-profile detail without compromising edge strength in light cuts. Avoid heavy interrupted cuts and unstable set-ups; when used in the intended continuous finishing regime, the insert supports predictable tool performance and contributes to a streamlined machining process with fewer reworks.

FAQ

What work is this insert designed for?
This insert is intended for precision external and internal turning, particularly finishing passes on steel where the NS9530 cermet grade yields low cutting forces and high surface quality.

Which materials are suitable with this grade?
The NS9530 cermet grade is a finishing sort optimised for steel; for other materials, select an appropriate grade and chipbreaker matching the workpiece and machining conditions.

What are the key geometry specifications?
The insert has a rhombic form with a 55° included angle, 11° relief, 0.8 mm corner radius and a thickness of 3.97 mm, providing a stable seating and fine edge for finishing operations.

How important is holder choice for performance?
Holder compatibility is critical: the insert’s performance depends on correct seating, clamping and the holder’s rigidity. ISO‑compliant holders matching the insert’s shape and tolerance class are recommended.

Is this insert suitable for interrupted cuts?
This finishing insert is intended primarily for continuous cuts and small depths of cut; interrupted or heavy cuts may reduce life and compromise surface finish.
