TPMR 160304 NS9530 — ISO triangular turning insert by Tungaloy for finishing operations

TPMR 160304-23 NS9530 is an ISO‑standard triangular indexable insert designed for external and internal turning, offering a finishing grade optimised for steel machining

• ISO‑standard triangular insert for turning
• Uncoated cermet NS9530 for high surface finish
• Sharp cutting edge for low cutting forces
• Suitable for continuous cuts and fine finishing

High‑quality finishing with uncoated cermet for steel

The insert uses an uncoated cermet grade (NS9530) developed for finishing steel where a sharp cutting edge and low cutting forces are decisive. Cermets combine ceramic and metallic phases to produce a hard, wear‑resistant cutting edge with excellent thermal stability; this makes the grade particularly effective in continuous cut scenarios and where small depths of cut are used. The result is improved surface finish and reduced tendency for built‑up edge, which supports repeatable part quality in serial production. Emphasis on edge sharpness reduces cutting energy and contributes to longer tool life under finishing conditions.

Consistent seating and geometry for stable turning results

The ISO design of the triangular insert ensures predictable seating in compatible holders: the combination of the 60° included angle, 11° relief angle and a 0.4 mm nose radius yields a balance between edge strength and surface quality. Compatibility with a toolholder depends on form, relief, tolerance class, clamping method, size and thickness; correct pairing secures stable chip formation and lowers vibration. The controlled geometry benefits dimensional consistency and reduces rework, especially when paired with a correctly rated external holder or boring bar and standard shim/clamp kits.

System approach for efficient shopfloor use

Planning the cutting operation around this insert supports process efficiency: the TPMR160304-23 format works within ISO holder systems and pairs with a matching chipbreaker (type 23) to control chip flow during finishing. The recommended system comprises the indexable insert, a matching external holder or boring bar, and the appropriate shim/clamp and replacement screws for secure mounting. This configuration minimises downtime for insert changes and helps maintain steady cycle times, while the finishing‑oriented cermet reduces the need for multiple passes to achieve target surface roughness.

FAQ

What materials is this insert intended for?
The TPMR160304-23 NS9530 is specified as a finishing grade for steel and performs best where a sharp edge and low cutting forces are required.

Can this insert be used for internal and external turning?
Yes, the triangular ISO geometry permits use in both external and internal turning when mounted in a suitable holder or boring bar.

What does the chipbreaker 23 indicate?
Chipbreaker 23 denotes the chip control geometry optimised for finishing cuts and continuous chip formation with this insert geometry and grade.

How does the 0.4 mm nose radius affect the finish?
A 0.4 mm nose radius provides a compromise between edge strength and surface quality; with the NS9530 cermet, it helps achieve fine surface finishes while maintaining adequate edge life.
