TPMT 16T304 NS9530 — TPMT16T304-PM ISO turning insert by Tungaloy

A TPMT16T304-PM NS9530 ISO turning insert designed for precision finishing in steel turning, suitable for both external and internal operations

• Triangle insert, 60° cutting geometry
• Cermet grade NS9530 for fine finishes
• 0.4 mm corner radius for precision
• 11° clearance angle, low cutting forces
• Cylindrical hole with single‑side countersink

Consistent finishing and material suitability

The NS9530 grade is an uncoated cermet developed for finishing applications on steel, providing a sharp cutting edge and low cutting forces that reduce tool chatter and improve component surface quality. This makes the insert particularly effective in continuous cut scenarios and for small depths of cut where a superior surface finish is required. The choice of cermet substrate results in good wear resistance during finishing cycles and stable edge condition over repeated parts, supporting predictable machining outcomes and fewer mid‑batch interventions.

Geometry engineered for reproducible accuracy

A controlled geometry contributes directly to process reliability: the 60° geometry in triangular form gives a defined cutting angle, while the 0.4 mm nose radius balances form accuracy and surface roughness. The 11° relief angle lowers friction at the flank face and helps maintain the sharp edge characteristic of this grade. Manufactured to ISO dimensions, the insert’s tolerances and sizes permit straightforward interchangeability with ISO‑compliant holders, simplifying tool changeovers and reducing set‑up time in mixed‑machine environments.

Secure clamping and robust insert body

Mechanical stability is ensured by the cylindrical hole with a single‑side countersink (40°–60°), which supports reliable clamping and repeatable seating in the toolholder. The 3.97 mm thickness of the insert enhances rigidity at the cutting edge, reducing vibration during light finishing passes and improving dimensional consistency. The triangular ISO format also offers multiple effective cutting edges per index, increasing economy of use and supporting uninterrupted production runs when combined with appropriate clamping components and replacement screws.

Recommended use cases and handling advice

Designed primarily for turning of steel, the insert performs best in finishing operations where small material removal rates and continuous cuts are common. Select the PM chipbreaker and NS9530 grade to favour surface quality and reduced burr formation. Ensure the matching holder corresponds to the insert’s form, relief, tolerance class, fastening method, size and thickness to achieve intended performance. Regular inspection of seat condition and replacement screws will maintain clamping accuracy and prolong the insert’s serviceable life.

FAQ

What materials is this insert suited for?
The TPMT16T304-PM NS9530 is formulated for turning steel with a finishing focus; the NS9530 uncoated cermet provides low cutting forces and excellent surface quality for continuous cuts.

How does the insert index and tool life behave in finishing jobs?
Thanks to the triangular ISO format and robust body, the TPMT16T304-PM from Tungaloy offers multiple usable edges and predictable tool life when used under recommended finishing conditions; SKU 6998558-Tungaloy identifies the exact article.

What clamping features must the holder provide?
The holder must accommodate the triangular ISO form, accept the cylindrical hole with single‑side countersink seating and match the insert thickness (3.97 mm) and relief angle for secure and repeatable clamping.

Is this insert suitable for internal and external turning?
Yes; the TPMT16T304-PM NS9530 is specified for both external and internal turning operations where a finishing grade and sharp cutting edge are required.

Which chipbreaker should be selected for best surface finish?
The PM chipbreaker paired with the NS9530 grade is recommended to favour surface quality and stable chip control during finishing cuts.
