TPMT 130302 NS9530 — TPMT 130302 NS9530 turning insert for finishing, Tungaloy

The TPMT130302-PS NS9530 is an ISO triangular indexable insert optimised for finishing operations in turning on steel, offering a precise cutting geometry for continuous cuts and small depths of cut.

• Sharp cutting edge for fine finishing
• Low cutting forces for stable machining
• Uncoated cermet grade NS9530
• ISO triangular form with 60° corner

Consistent finishing brought by cermet technology

The uncoated cermet NS9530 is formulated for reliable finishing on steel, combining a sharp cutting edge with reduced built‑up edge tendency. This results in lower cutting forces, which in turn minimises vibration and enables stable turning at small depths of cut. The practical effect is fewer rejects and more predictable batch runs, especially where a high‑quality surface finish is required. The material's behaviour in continuous cutting makes the insert particularly suitable for light finishing passes where dimensional accuracy and surface integrity are priorities.

Design and geometry that simplify tool selection

With a triangular shape and a 60° corner, the insert delivers good access to external and internal profiles while offering three usable cutting edges. The specified 0.2 mm corner radius balances strength and form accuracy, producing fine toolmarks without compromising edge life. The 11° relief angle reduces cutting resistance, supporting smooth chip flow when paired with an appropriate holder. Being ISO‑standardised, compatibility with a wide range of holders is determined by form, clearance angle, tolerance class, fixing method, size and thickness — this makes system integration straightforward in existing tool setups.

Practical chip control and holder integration

Equipped with a PS chipbreaker, the insert supports short, controllable chips during finishing, reducing the need for special chip management. The plate features a cylindrical hole with a one‑sided countersink (40°–60°) for secure clamping and repeatable seating. As part of a typical system — indexable insert, compatible external holder or drill bar, backing pad/clamping set and spare screws — the component allows rapid changeover and predictable repeatability on production lines. These design choices reduce downtime and maintain throughput in medium‑volume turning operations.

Material, application and operational benefits

Although compact in size, the insert delivers measurable gains: the uncoated cermet composition enhances wear resistance at finishing speeds, while the geometry is optimised for continuous cutting and small feed rates. For shops aiming to improve surface quality without significant process changes, this insert offers a practical route to better part finish and reduced secondary processing. The consistent performance also supports traceable process control, which is advantageous for regulated or high‑precision manufacturing environments.

FAQ

What material is the insert designed to machine?
The insert is optimised for machining steel; the NS9530 cermet composition is tuned for finishing on steel with improved surface quality.

Is this insert compatible with standard ISO holders?
Compatibility depends on holder form, relief angle, tolerance class, fixing method, size and plate thickness; the insert follows ISO‑standard dimensions for straightforward integration.

What does the PS chipbreaker provide?
The PS chipbreaker promotes controlled, short chips during finishing, aiding safe chip evacuation and reducing the need for elaborate chip management.

Can the insert be used for roughing operations?
This grade and geometry are intended for finishing and small depths of cut; for heavy roughing, a different grade with higher toughness is recommended.

How many usable cutting edges does the triangular insert offer?
The triangular design provides three cutting edges per indexable plate, enabling quick rotation when an edge is worn.
