TPMR160304 NS9530 turning insert — triangular insert, 0.4 mm radius, 11° clearance | Tungaloy

The TPMR160304 NS9530 is an ISO‑standard triangular turning insert designed for precision finishing of steel in continuous turning applications.

• ISO‑standard triangular insert
• Uncoated cermet NS9530 for fine finishing
• Corner radius 0.4 mm for consistent surface
• 11° clearance and one‑sided chipbreaker

Superior surface finish with lower cutting forces

The uncoated cermet composition NS9530 is engineered as a finishing grade that provides a very sharp cutting edge and reduced cutting forces, which directly benefits surface quality when turning steel. The low edge strength of the grade is deliberate: it produces minimal built‑up edge and promotes stable cutting at small depths of cut, making it ideal for continuous fine finishing and short‑chip formation. The combination of the 0.4 mm corner radius and the sharp cermet enables improved plateaus and reduced need for secondary finishing, translating into shorter process chains and less rework.

Consistent fit and straightforward mounting for productivity

Compatibility with the toolholder is governed by geometry: form, clearance angle, tolerance class, fastening method, size and thickness. The ISO designation guarantees interchangeability with holders designed for the TPMR form; the 11° clearance eases chip flow while maintaining a controlled shear zone. The insert is supplied without a hole, requiring a compatible clamp or screw system; the triangular format provides three usable cutting edges per insert, improving cost efficiency per edge change. Clear identification of size and thickness allows predictable seating and repeatable runout, which reduces set‑up time and improves first‑pass yield.

Improved process stability during continuous turning

A one‑sided chipbreaker tailored for finishing supports consistent chip formation in uninterrupted cuts, keeping forces steady and avoiding vibration at light feeds. The triangular geometry contributes to mechanical stability in the clamping pocket, while the thin 3.18 mm thickness balances rigidity with accessibility in tight turning envelopes. Where small depth‑of‑cut finishing is required, the combination of grade and geometry affords a reliable tool life, ensuring repeatable dimensional results and a stable surface roughness across batches.

Economical finishing with predictable results

For high‑volume finishing where repeatability matters, the insert delivers predictable performance and lower overall process cost. The NS9530 grade’s emphasis on surface finish reduces dressings and downstream polishing. Traceable identifiers—manufacturer SKU and article numbers—support inventory management and reorders; the ISO‑compliant system structure simplifies sourcing of matching holders, shims and replacement screws, promoting lean production workflows. The net result is a finishing solution that is technically clear, practical and designed for productive turning operations.

FAQ

What materials is this insert suited for?
The NS9530 finishing grade is optimised for steel; the TPMR160304 insert performs best in continuous turning operations on steel where a high surface finish is required.

Is this insert compatible with standard TPMR holders?
Yes. The TPMR160304 follows ISO geometry so compatibility is determined by the holder’s form, clearance angle, tolerance class, fastening and pocket thickness.

How many cutting edges are available per insert?
The triangular format provides three usable cutting edges; rotation yields multiple dressings before the insert must be replaced.

What is the function of the one‑sided chipbreaker?
The one‑sided chipbreaker is configured for finishing: it supports short, controlled chip formation suitable for continuous cuts and helps maintain low cutting forces and a stable surface finish.

Which identifiers should be used when reordering?
Use the article number 6998568 and manufacturer SKU TUN6998568 when reordering to ensure the correct TPMR160304 NS9530 Tungaloy turning insert is supplied.
