TPGT16T308 NS9530 — Tungaloy indexable insert for turning, finishing grade, 60°

A TPGT16T308 NS9530 ISO-format insert engineered for finishing turns on steel, offering a sharp cutting edge, low cutting forces and controlled chip formation for continuous cuts.

• ISO 16T308 geometry, 60° included angle
• Uncoated cermet NS9530 for fine finishing
• Cylindrical hole with single-sided countersink
• 0.8 mm corner radius for small depth cuts

Achieve superior surface finish with a finishing-grade cermet

The uncoated cermet grade NS9530 combines a fine-grained ceramic matrix with metallic binder phases to maintain a very sharp cutting edge. This material choice reduces built-up edge and lowers cutting forces, which translates to consistently improved surface quality on steel during finish turning. For applications with small depths of cut and continuous cutting, the insert significantly reduces the need for manual rework while supporting tighter dimensional tolerances. The result is reliable, repeatable finishing performance suited to precision components.

Reliable geometry and secure mounting for stable machining

Designed with a 60° included angle and an 11° clearance at the cutting face, the insert offers predictable engagement and reduced radial forces. The triangular form with a cylindrical hole and single-sided countersink (40°–60°) enables positive location and secure clamping in compatible ISO holders. Compatibility depends on the holder’s form, relief angle, tolerance class, fastening method, size and thickness; the ISO series system requires a matching outer holder or boring bar, a suitable shim or clamp set and replacement screws for safe assembly. This systematic approach minimises vibration and ensures repeatable positioning.

Practical benefits in process and tool management

With a 0.8 mm corner radius the insert is ideal for finishing passes and small feed conditions where edge strength and surface integrity matter. The single-sided chipbreaker supports effective chip control in fine-turning regimes, reducing the risk of surface damage and improving cycle stability. The insert’s geometry and cermet composition favour continuous cuts and low-feed finishing, making it a practical choice for shop floors seeking consistent part quality without complex parameter tuning.

Selecting the right grade and integrating into workflows

As part of an ISO indexable insert system, this turning insert is intended to be used with holders specified for triangular inserts of 16 mm size. The TPGT16T308 variant combines the finishing-focused NS9530 grade with a 3.97 mm thickness to balance rigidity and cutting access on turned parts. For new setups, select a holder and clamping kit that match the insert’s form and thickness; for existing fixtures, verify tolerance class and fastening compatibility. Where tool life and surface finish are priorities, the finishing cermet helps to extend effective process windows and reduce secondary operations.

FAQ

What materials is this insert designed for?
The NS9530 finishing grade is optimised for steel; the Tungaloy TPGT16T308 insert gives a sharp edge and low cutting forces suited to fine finishing on steel workpieces.

How does the uncoated cermet grade compare to coated carbide for finishing?
Uncoated cermet like NS9530 maintains a sharper edge and lowers cutting forces compared with many coated carbides, making it preferable for final passes where surface finish is critical on steel.

Which holder features must be checked for compatibility?
Compatibility requires a holder matching the insert’s triangular form, 3.97 mm thickness, relief/clearance angle and fastening style; verify tolerance class and clamp fit before assembly with the TPGT16T308 insert.

What cutting conditions suit this insert best?
The insert excels in low-depth, continuous finishing cuts and small feed rates where its 0.8 mm corner radius and chip control deliver consistent surface quality.

Is the chip control handled by the insert geometry or coating?
Chip control is delivered by the one-sided chipbreaker geometry; NS9530 is uncoated, so chip behaviour relies on the insert form and cutting parameters rather than a coating.
