TPMT 130308 NS9530 — ISO triangle turning insert for finishing (Drehen), Tungaloy

The TPMT130308-PSS NS9530 is an ISO-compliant triangle insert designed for external and internal turning, optimised as a finishing grade for steel with continuous cuts and small depth of cut.

• ISO triangle form for standardised holders
• Cermet NS9530 for excellent surface finish
• Low cutting forces for continuous finishing cuts
• 0.8 mm corner radius for precision edges

Engineered for consistent finishing and low cutting forces

This insert combines an uncoated cermet NS9530 grade with a sharp cutting edge to deliver low cutting forces and an improved finish when machining steel. As a finishing solution, the geometry reduces the load on the tool and the workpiece, which helps achieve tighter dimensional tolerances and a finer surface without the need for extensive secondary operations. The combination of grade and geometry is particularly suited to stable setups and continuous cutting where surface integrity is a priority.

Geometry and clamping designed to simplify tool selection

The insert is ISO-compliant, which streamlines holder compatibility because form, 11° clearance, tolerance class, attachment and thickness are standardised. The PSS chipbreaker is matched to the finishing application to control chips in small depths of cut, while the cylindrical hole with single-side countersink (40°–60°) supports secure clamping and repeatable positioning. Critical dimensions such as the 60° included angle, 3.18 mm thickness and 0.8 mm corner radius are selected to balance edge strength with the ability to produce fine surface finishes.

Practical advantages in production and process planning

Using this insert for turning reduces the need for post-machining and supports predictable process windows, which benefits cycle time and downstream handling. The cemented carbide substrate offers stable edge retention for finishing passes in steel, and the combination of grade and chipbreaker reduces risk of built-up edge under continuous cutting. For best results, select a holder and clamping system compatible with ISO TPMT geometry and verify insert seating and seat tolerance to ensure repeatability in serial production.

FAQ

What materials is this insert intended for? The TPMT130308-PSS NS9530 is a finishing-grade insert developed primarily for machining steel; the NS9530 cermet provides a sharp edge and improved surface quality in continuous finishing cuts.

Which holders are compatible with this triangle insert? Compatibility depends on ISO triangular insert seats that match the TPMT form, 11° clearance, thickness 3.18 mm and the 13 mm inscribed circle; ensure the holder accepts a TPMT-style insert and the specified clamping arrangement.

How does the PSS chipbreaker influence machining? The PSS chipbreaker is designed to promote controlled chip formation in finishing operations, reducing the tendency for long stringy chips and helping to maintain a consistent surface finish during small depth cuts.

Is the TPMT130308-PSS NS9530 suitable for internal turning? Yes, the geometry and NS9530 finishing grade make this insert suitable for internal and external turning where fine surface quality and low cutting forces are required; verify holder reach and rigidity for internal applications.
