TNMG 160408 NS9530 indexable insert for turning — Tungaloy, uncoated cermet, 0.8 mm radius

TNMG160408 NS9530 is an ISO‑standard triangular indexable insert intended for finishing operations in turning, offering a sharp cutting edge and consistent surface quality.

• ISO‑standard TNMG 160408 geometry
• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge for high surface finish
• Double‑sided chipbreaker with cylindrical hole

High‑quality finishing with low cutting forces

The TNMG160408 NS9530 insert is engineered as a finishing grade: the uncoated cermet composition and the fine edge geometry deliver low cutting forces and a superior surface finish on steel. Cermet combines ceramic hardness with metallic toughness, which reduces built‑up edge formation and supports continuous cuts with small depths of cut. The result is a repeatable machined surface and lower rework rates, which contributes to predictable cycle times in production.

Reliable fit and ISO compatibility for flexible tool chains

ISO standardisation ensures precise interchangeability: the 60° included angle and triangular form match holders and boring bars designed for TNMG inserts. Key dimensions such as the inscribed circle (16 mm), plate thickness 4.76 mm and the cylindrical hole define compatibility with clamping sets and replacement screws. Using standardised geometry simplifies tool inventory and allows seamless integration into existing tool posts without compromise to concentricity or clamping stability.

Improved chip control and machining stability

The double‑sided chipbreaker provides controlled chip formation for finishing feeds and steady metal evacuation. Stable chip control reduces vibration and protects the cutting edge, enabling consistent performance across repeated cycles. For best results, pair the insert with a rigid external holder or boring bar and select a chipbreaker and grade combination that suits the workpiece and machining strategy to maximise productivity and edge life.

Process recommendations for turning applications

Intended primarily for turning and fine finishing of steel, the insert performs best in continuous cuts and small feed ranges; the corner radius of 0.8 mm supports edge strength while maintaining a fine profile on the workpiece. The insert is supplied as part of an ISO insert system that typically includes a matching external holder or boring bar, a shim/clamping set and replacement screws. Matching toolholder stability and correct clamping torque will help exploit the NS9530 grade’s advantages and ensure repeatable results.

FAQ

What materials is this insert suitable for?
The TNMG160408 NS9530 is specified as a finishing grade for steel and is optimised to deliver low cutting forces and improved surface finish when machining steel.

What are the key geometrical characteristics of the insert?
The TNMG160408 feature set includes a 16 mm inscribed circle, a 60° included angle, a 0.8 mm corner radius and a plate thickness of 4.76 mm, with a cylindrical hole for standard clamping.

Is the insert reversible or single‑use?
The insert is double‑sided with a chipbreaker on both faces, allowing indexation to a fresh cutting edge when one side is worn.

Which holder type is recommended for this geometry?
Use an ISO‑compatible external turning holder or boring bar that accepts TNMG‑style triangular inserts with a 60° included angle and a cylindrical hole clamping system.

What cutting conditions are suggested for best results?
For finishing applications, employ continuous cuts with modest depths of cut and feed rates suitable for the NS9530 cermet grade; ensure a rigid tool setup to exploit the insert’s low cutting force characteristics.
