TPMT 16T304 NS9530 ISO turning insert — uncoated cermet for finishing, Tungaloy

The TPMT16T304-PS NS9530 is an ISO turning insert engineered for precision external and internal turning, optimised for continuous finishing cuts on steel with low cutting forces and excellent surface quality.

• TPMT16T304-PS NS9530 uncoated cermet grade
• Sharp edge for high surface finish
• PS chipbreaker for continuous cuts
• 11° rake angle and 0.4 mm corner radius

Achieve consistently superior surface finishes with a finishing-grade cermet

The uncoated cermet grade NS9530 is designed for finishing operations on steel, offering a very sharp cutting edge and reduced built-up edge tendency. This combination yields improved surface integrity at low depths of cut and supports continuous cutting conditions. The insert’s geometry and material reduce cutting forces, which in turn lowers vibration and helps produce repeatable part quality. For processes where surface roughness and dimensional consistency are critical, the composite ceramic-metal cutting material provides the edge retention and thermal stability required for extended finishing runs.

Clear compatibility criteria to match the correct holder and clamping

Compatibility with a toolholder depends on several defined parameters: insert form and size, rake angle, tolerance class, clamping and fastening method, thickness and locating hole geometry. This triangular insert uses an ISO-style designation and a cylindrical hole with a single-sided countersink (40°–60°); the correct seat and screw must be selected to ensure secure fixation and optimal cutting geometry. Checking holder specifications against these characteristics prevents misalignment and ensures the intended cutting angle and clearance are maintained during turning operations.

Productivity benefits from geometry and chip control

The PS chipbreaker is tailored for small depths of cut and continuous feeds, promoting short, controllable chips that evacuate reliably in stable machining conditions. Combined with the 0.4 mm corner radius and 11° rake, the geometry supports low cutting forces and high surface finish without sacrificing edge robustness. The cermet composition delivers a fine balance between hardness and toughness, making the insert particularly effective for finishing passes where minimal vibration and consistent tool life are priorities—contributing to predictable cycle times and reduced rework.

Practical application advice and handling notes for reliable performance

Use this insert for precision external and internal turning where continuous cuts and fine finishing are required; its 16 mm inscribed size and 3.97 mm thickness suit compact to medium-duty holders. For best results, pair the insert with a holder that matches the ISO seat and provides rigid clamping; ensure cutting parameters are conservative during initial trials to confirm stability. As an uncoated grade, the insert performs best at moderate cutting speeds typical of finishing operations; monitoring wear and replacing inserts before edge chipping preserves part quality and process reliability.

FAQ

What materials is this insert suitable for?
The TPMT16T304-PS NS9530 is a finishing-grade cermet insert optimised for machining steel, delivering low cutting forces and high surface quality during continuous finishing cuts.

Which turning operations are appropriate for this grade?
Ideal uses include external and internal finishing passes where small depths of cut and consistent surface finish are required; the PS chipbreaker aids chip control in continuous feeds.

How is compatibility with a toolholder determined?
Compatibility is based on insert form and size, rake/clearance angles, tolerance class, clamping method, thickness and locating hole geometry; verify that the chosen holder matches these parameters.

What does the PS chipbreaker do in practice?
The PS chipbreaker produces short, controllable chips under continuous cutting conditions, improving evacuation and helping to maintain stable machining and surface quality.

Is the insert coated and what are the implications?
This is an uncoated cermet grade; the lack of coating gives a very sharp edge for finishing and reduced cutting forces, though thermal and adhesion behaviours differ from coated carbide grades.
