TCMT 16T304 NS9530 — Tungaloy triangle finishing turning insert (60°)

A TCMT16T304 NS9530 ISO turning insert designed for finishing steel, offering a sharp edge, low cutting forces and compatibility with ISO toolholders

• Finishing grade NS9530 for steels
• Uncoated cermet for low cutting forces
• Triangle insert with 60° included angle
• Cylindrical hole with 40°–60° countersink

Superior finishing performance for steel turning

The NS9530 grade is an uncoated cermet specifically developed as a finishing sort for steel, delivering a high surface finish and low cutting forces in continuous cutting conditions and small depths of cut. Cermet materials combine ceramic hardness with metallic toughness, reducing built-up edge and improving dimensional consistency compared with standard cemented carbide grades. For operations where surface integrity and repeatable finish are priorities, the geometry and material pairing ensure consistent results while keeping cutting forces moderate, which benefits spindle and fixture loads.

Geometry and chip control that boost productivity

A triangular insert with a 60° included angle and a 0.4 mm corner radius provides a controlled contact area and predictable edge engagement, which is ideal for fine finishing passes. The single-sided chipbreaker design supports efficient chip formation during external and internal turning, reducing the risk of long swarf and improving process security. Together, these features promote longer edge life under steady feed conditions and contribute to smoother cycle times and less rework—advantages that translate directly into higher throughput and lower unit costs.

Fast integration into ISO tool systems for simple changeovers

Designed within the ISO turning insert system, the TCMT16T304 format matches standard holder forms and fixation parameters: size 16 with a plate thickness of 3.97 mm and a clearance angle of 7°. The insert is supplied with a cylindrical hole and single-sided countersink (40°–60°), ensuring secure clamping in compatible holders and easy positioning during toolset changes. Compatibility depends on form, clearance angle, tolerance class, fastening and thickness; correct matching with an ISO external holder or boring bar guarantees stable clamping, repeatable seating and straightforward inventory management across workshops.

Material and application guidance for reliable selection

Made from cemented carbide and specified as a finishing cermet, this insert is best applied to steels under continuous cutting regimes and small cross-sections where high surface quality is required. The combination of a sharp edge and the NS9530 microstructure reduces plastic deformation at the cutting edge and limits rubbing, which helps achieve the targeted finish without excessive feed reduction. For selection: pair the insert with a holder that matches the 16T304 ISO code and verify the clamp and seat geometry; for further process optimisation, Metav Werkzeuge can advise on matching chipbreaker and parameter settings for specific steel grades.

FAQ

What materials is this insert best suited for? The TCMT16T304 NS9530 Tungaloy turning insert is specified as a finishing cermet for steel, providing excellent surface quality in continuous cutting and small-depth finishing operations.

How does the NS9530 grade affect cutting performance? NS9530 is an uncoated cermet grade that reduces built-up edge and cutting forces, which helps achieve a smoother surface finish and more consistent dimensional results compared with conventional grades.

Which geometry details ensure stable clamping in holders? The TCMT16T304 features a triangle form with a cylindrical hole and a single-sided countersink (40°–60°); coupled with the 16 mm size and 3.97 mm thickness, this ensures secure seating in compatible ISO holders.

Is the insert suitable for both external and internal turning? Yes, the insert’s single-sided chipbreaker and triangle geometry make it suitable for external and internal turning tasks where finishing performance is required.

How should the insert be matched to a toolholder? Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; match the TCMT16T304 NS9530 to an ISO holder with a 7° clearance and appropriate clamp to ensure repeatable seating and process stability.
