TPGT 090202 NS9530 Tungaloy turning indexable insert — 0.2 mm radius, 11° relief

The TPGT090202 NS9530 is a triangular ISO turning insert intended for finishing steel, offering a sharp edge geometry for continuous cuts and small depths of cut.

• ISO triangular insert, size 09
• Uncoated cermet finishing grade NS9530
• 11° relief angle for low cutting forces
• Cylindrical hole with 40°–60° countersink

Achieve superior surface finish with a finishing-grade cermet

The uncoated cermet composition (NS9530) is optimised as a finishing grade for steel, delivering a sharp cutting edge and low cutting forces that reduce vibration and tool chatter. For operations with continuous cutting and modest depths of cut, this material combination improves part tolerances and reduces the need for secondary finishing, which supports a more efficient production flow. The result is a consistent high surface finish and reliable dimensional accuracy on turned components.

Designed to fit ISO toolholders with clear mounting parameters

The insert follows ISO geometry and fits into compatible triangular holders when form, relief angle, tolerance class, fastening and plate thickness are matched. Key mounting values — 11° relief angle, 2.38 mm thickness and a cylindrical hole with one-sided countersink (40°–60°) — ensure reproducible clamping and stable seating in standard toolposts. Pay attention to the holder’s seat and screw arrangement: correct pairing avoids runout and preserves the intended cutting geometry and surface quality.

Practical advantages for reliable process performance

Choosing a finishing-grade insert brings measurable process benefits: reduced cutting forces lower machine load and can permit higher feed rates within finish limits, while the 0.2 mm corner radius preserves a crisp edge for fine detail on external and internal profiles. The one-sided chipbreaker supports chip control in stable setups and reduces the risk of re-cutting, which enhances cycle-time predictability and part-to-part consistency. These practical advantages translate into better throughput and fewer reworks in precision turning applications.

Guidance for selecting the right chipbreaker and setup

Typical applications include external and internal turning of steel where surface quality and dimensional control are priorities. Select the chipbreaker and grade that match the workpiece material, machining type and setup stability: the NS9530 grade is tailored for finish passes and small depth-of-cut conditions. Ensure the toolholder and clamping kit (underlay/clamp and replacement screws) correspond to the insert’s ISO designation and hole style to guarantee secure mounting and repeatable performance.

FAQ

Which materials is this insert intended for?
The NS9530 finishing grade is intended primarily for steel; the TPGT090202 NS9530 Tungaloy indexable insert performs best on continuous cuts and small depths of cut when a high surface finish is required.

Can the insert be used for internal turning as well as external turning?
Yes — the insert is suitable for both external and internal turning operations when mounted in an appropriate ISO-compatible holder and used with stable machining parameters.

What are the key dimensions to check when selecting a holder?
Check the insert designation (TPGT090202), 11° relief angle, 2.38 mm thickness, size 09, and the hole style (cylindrical hole with one-sided countersink) to ensure the holder seat and fastening match.

Is the cutting material coated?
The cutting material is an uncoated cermet (NS9530), selected to provide a sharp edge and superior surface quality in finishing applications.

How does the 0.2 mm corner radius influence results?
A 0.2 mm corner radius maintains a fine edge that enhances surface finish and detail definition while distributing cutting forces in finish passes; it is well suited to tight-tolerance turning.
