TPMT090208 AT9530 triangular indexable turning insert, coated cermet, Tungaloy

TPMT090208 AT9530 is a triangular, ISO‑standard indexable insert designed for precision turning and light finishing operations on steel.

• Coated cermet grade AT9530
• Triangular 60° insert form
• 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink

Delivering consistent surface finish with a coated cermet grade

The combination of a coated cermet cutting material and the AT9530 grade is aimed at achieving a high‑quality surface finish during finishing and light machining of steel. The AT9530 coating promotes even wear across the cutting edge, reducing the need for frequent index changes and helping to maintain dimensional stability over longer runs. By prioritising surface integrity, the insert supports processes where finish and repeatability are decisive, making it suitable for small‑batch precision components as well as higher‑volume finishing passes.

Secure clamping and ISO compatibility for reliable set‑ups

Compatibility with the toolholder is governed by precise factors such as form, clearance angle, tolerance class, fastening method, size and thickness. The triangular 60° geometry combined with a cylindrical hole and single‑sided countersink (40°–60°) ensures secure clamping in compatible holders and boring bars. Specifying the correct holder and matching shim or clamp prevents movement under cutting forces and maintains repeatable positioning. Systematically checking these parameters simplifies set‑up and reduces downtime when replacing inserts.

Geometry tailored to finishing cuts and controlled chip formation

With a 0.8 mm corner radius and a plate thickness of 2.38 mm, the insert is optimised for light engagement and finishing feed rates; the modest radius balances edge strength with the ability to produce fine surface textures. The one‑sided chipbreaker supports predictable chip formation in finishing cuts, while the triangular shape offers three usable corners per insert, improving cost efficiency. In practice, this geometry helps stabilise cutting action and contributes to uniform wear distribution when paired with appropriate feeds and depth of cut for finishing operations.

FAQ

What materials is this insert intended for?
This insert is specified for finishing and light machining of steel; the AT9530 coated cermet is optimised for achieving superior surface quality and even wear when used on steel.

How does the 0.8 mm corner radius influence performance?
A 0.8 mm corner radius provides a compromise between edge strength and fine surface generation; it helps to smooth the turned surface while retaining sufficient edge stability for finishing passes.

Which holder characteristics must be checked for compatibility?
Compatibility depends on form, clearance angle (11°), tolerance class, fastening method, size (09) and thickness (2.38 mm); matching these parameters to an ISO‑compliant holder ensures correct seating and clamping of the insert.

Why is the hole and countersink design important?
The cylindrical hole with a single‑sided countersink (40°–60°) secures the insert under clamping forces and aligns the insert consistently in the pocket, contributing to repeatable cutting geometry and safer tool operation.

Can this insert be used for internal and external turning?
Yes — the model series and geometry support both external and internal turning, provided the selected holder and chipbreaker are appropriate for the intended turning operation and workpiece stability.
