TPGM 070102 NS9530 – Tungaloy turning insert (uncoated cermet, 60°)

The TPGM070102 NS9530 is an ISO-standard triangular indexable insert designed for external and internal turning, optimised for fine finishing of steel with continuous cuts.

• Sharp cutting edge for superior surface finish
• Uncoated cermet grade NS9530 for low cutting forces
• ISO 070102 triangular form, 60° included angle
• Single-sided chipbreaker for reliable chip control

Consistent fine finishing thanks to the cutting concept

The combination of a sharp cutting edge and the uncoated cermet NS9530 grade delivers noticeably improved surface quality on steel during finishing passes. Cermet materials offer a harder, more wear-resistant cutting edge than conventional grades, which reduces built-up edge and stabilises the cutting action in continuous cuts. For applications with small depths of cut and a priority on surface integrity, the insert’s geometry ensures low cutting forces and a clean part finish.

Compatibility and secure mounting for reliable production

This insert follows ISO-standard dimensions and is specified as TPGM 070102, so compatibility with appropriate triangular holders is determined by form, relief angle, tolerance class, fastening method, size and thickness. The insert features a cylindrical hole for positive clamping and a 1.59 mm thickness that matches standard clamping sets. Correct pairing with a suitable external holder or boring bar preserves repeatable seat location and tool life.

Chip control and stability in steady cutting conditions

With a single-sided chipbreaker designed for continuous cutting, the insert produces short, manageable chips under the recommended feeds and depths. The moderate 0.2 mm corner radius balances edge strength and fine surface finish: the radius helps absorb cutting forces while keeping profile accuracy. For stable processes and consistent results, select feeds and depths aligned with finishing parameters rather than heavy roughing cuts.

Material grade, application and practical recommendations

The NS9530 grade is formulated as an uncoated cermet for finishing steel, offering low friction and reduced adhesion tendencies. This makes the insert particularly suitable for achieving high-quality surfaces in uninterrupted turning operations. Where interrupted cuts or heavy-duty roughing are required, alternative grades or coated solutions should be considered to preserve edge life and process security.

FAQ

What material is the insert intended for?
The TPGM070102 NS9530 is specified as an uncoated cermet grade optimised for finishing operations on steel.

Can this insert be used for internal boring as well as external turning?
Yes, the ISO triangular geometry and cylindrical hole permit use in appropriate external holders and boring bars for both external and internal turning.

How does the 0.2 mm corner radius affect the finish?
A 0.2 mm corner radius provides a compromise between edge strength and surface quality, reducing the risk of edge chipping while supporting a fine finish.

Is the chipbreaker suitable for interrupted cuts?
The single-sided chipbreaker is tailored to continuous cutting and fine finishing; for frequent interruptions or heavy roughing, a different chip control geometry is recommended.

Which specification determines holder compatibility?
Compatibility is set by the insert’s form, relief angle, tolerance class, fastening method, size and thickness, so matching the ISO 070102 designation with a suitable holder is essential.
