TPGT 16T308 NS9530 — TPGT16T308 Tungaloy turning insert (Finishing, ISO)

TPGT16T308 NS9530 is a triangular ISO indexable insert for precision turning, optimised as a finishing grade for Stahl with a sharp cutting edge and low cutting forces

• ISO‑standard triangular insert 16 mm
• Uncoated cermet grade NS9530 for finishing
• Sharp edge with low cutting forces and high finish
• Cylindrical hole with single‑side countersink

Precision finishing for demanding turning operations

The insert is an ISO‑standardised triangular indexable insert designed for high‑quality finishing passes. Built from cemented carbide and specified as an uncoated cermet NS9530, the geometry and material pairing produce a sharp cutting edge and low cutting forces, which together minimise tool deflection and enhance dimensional control during continuous cuts and light depths of cut. The result is a consistent surface integrity with reduced need for rework. Compatibility with toolholders is determined by form, relief angle, tolerance class, fastening method, size and thickness, which ensures predictable seating and repeatable performance when the correct holder is selected.

Stable geometry and secure seating for reliable tool life

The triangular form with an included angle of 60°, a corner radius of 0.8 mm and a relief angle of 11° provides a robust cutting geometry that supports the finishing application. A cylindrical hole with a single‑side countersink (40°–60°) and a plate thickness of 3.97 mm give stable clamping and repeatable position accuracy in the pocket. The one‑sided chipbreaker is matched to the grade for controlled chip formation during finishing passes, reducing vibration and improving surface finish. Because the grade is uncoated, wear behaviour is highly predictable under light finishing conditions, making it a suitable choice for consistent, high‑quality results on Stahl.

Application guidance and system considerations

Intended primarily for external and internal turning, this insert performs best in finishing applications where small feed rates and shallow cuts are used. Select the corresponding holder, clamp set and fastening screws that match the insert form, tolerance class and thickness to ensure full ISO compatibility. Where high surface quality and low cutting forces are priorities, the NS9530 cermet offers a balance of wear resistance and edge sharpness. If there is any uncertainty about holder selection, cutting data or chipbreaker choice, technical advisors can clarify the correct combination of insert grade and tool system to suit the component and machining conditions.

FAQ

What materials is this insert intended for?
The TPGT16T308 NS9530 insert is specified as a finishing grade for Stahl, offering a sharp edge and controlled wear suited to fine finishing passes.

Is the insert coated or uncoated?
This insert uses an uncoated cermet NS9530 grade, which provides a sharp cutting edge and predictable wear behaviour for finishing applications.

Which toolholders are compatible with this insert?
Compatibility depends on the holder’s pocket form, relief angle, tolerance class, fastening method, size and plate thickness. Use a holder designed for ISO TPGT inserts and verify the pocket matches the TPGT16T308 dimensions.

How does the corner radius affect the machining result?
The 0.8 mm corner radius balances edge strength and surface finish; it helps reduce chatter while delivering the improved surface quality expected from finishing inserts.

What is the purpose of the countersunk hole?
The cylindrical hole with single‑side countersink (40°–60°) ensures secure clamping and correct seating in the pocket, aiding repeatability and positional stability of the indexable insert.
