DPMT 070208 NS9530 — ISO rhombic turning insert for precision finishing, Tungaloy

DPMT 070208 NS9530 is an ISO rhombic turning insert designed for finishing operations on steel, offering a sharp cutting edge and a format compatible with standard ISO holders.

Rhombic insert size 07 Cermet grade NS9530 for finishing 11° clearance angle for sharp cutting Cylindrical hole with countersink

High-precision finishing with reduced cutting forces

The insert combines an uncoated cermet composition with a finely honed geometry to deliver low cutting forces and an excellent surface finish during continuous turning operations. The NS9530 grade is optimised as a finishing sort for steel, providing a sharp cutting edge and stable edge retention at small depths of cut. Thanks to the fine-grain substrate and polished cutting face, the component machining process often requires fewer secondary operations, saving cycle time and lowering total process cost while maintaining dimensional consistency.

Reliable fit and secure mounting for ISO systems

As an ISO-compliant rhombic insert, the item integrates into standard turning systems where compatibility depends on shape, relief angle, tolerance class, fastening and thickness. The rhombic geometry and cylindrical hole with single-sided countersink (40°–60°) ensure reproducible seating and clamping in matching holders, while the 11° clearance and 55° included angle support effective chip formation for finishing cuts. Choosing the correct holder and clamping set maintains repeatability and avoids unexpected tool movement, which protects workpiece quality.

Material behaviour and machining advantages of the cermet grade

Built on a cemented carbide substrate and finished as an uncoated cermet, the insert excels in continuous-feed finishing of steel by reducing built-up edge and improving edge stability at low to moderate cutting speeds. The cermet chemistry offers a balance between wear resistance and a fine cutting edge, which translates into superior surface quality on turned components. This behaviour makes the insert well suited for both external and internal turning where smooth, consistent surfaces are required and where small feeds and light depths of cut are the norm.

Productivity improvements and selection guidance

Selecting this insert with the appropriate single-sided chipbreaker and matching grade for the workpiece stability enhances productivity by reducing rework and inspection time. The modest corner radius (0.8 mm) supports fine finishing without compromising dimensional control, while the standardised ISO 070208 designation simplifies tool management and reordering. For applications requiring high surface integrity, this combination of geometry and NS9530 grade delivers repeatable results and contributes to overall process efficiency.
