• 0.2 mm corner radius for fine turning operations
• One-sided chipbreaker with centre hole fitment

Improved surface quality and predictable wear for finishing

The AT9530 composition is a coated cermet developed for finishing and light machining of steel, prioritising a consistent surface finish and even wear behaviour. With a 0.2 mm corner radius and a 60° insert geometry, this grade reduces the risk of built-up edge and supports stable cutting conditions at finishing feeds. The choice of a cermet compound provides a balance between hardness and toughness, which helps to maintain edge integrity during intermittent cuts and to deliver repeatable dimensional results. These properties make the insert particularly suitable where surface integrity and reduced polishing are decisive.

Secure clamping and ISO compatibility for predictable setups

Compatibility with clamping systems follows ISO standards; fitment depends on insert form, relief angle, tolerance class, fastening method, size and thickness. The triangular shape and ISO designation ensure broad compatibility with standard holders and boring bars intended for TPMT formats. The insert is supplied with a cylindrical hole and a single‑side countersink (40°–60°), enabling consistent seating and straightforward replacement during production. The nominal thickness of 2.38 mm contributes to stable clamping and predictable stiffness in light turning applications, which supports process reliability on flexible machinery and automatic tool changers.

Material and geometry that extend operating windows

Made from cemented carbide, the insert benefits from a substrate designed for dimensional stability under thermal load. The AT9530 coating and structure aim to keep flank wear uniform, extending the useful life of the cutting edge in finishing cycles. The one‑sided chipbreaker is optimised for chip control during finish passes, reducing risk of surface damage and easing swarf evacuation. Together, the substrate, coating and geometry widen the effective operating window by allowing slightly higher cutting speeds compared with uncoated grades, while retaining the fine edge necessary for high‑quality surface outputs.

Practical application advice and selection guidance

When specifying an insert for fine turning, match the AT9530 grade to steels where surface finish and low wear are priorities rather than aggressive material removal. The triangular TPMT form supports multiple indexing positions, improving economy for finishing tasks. For roughing or heavy interrupted cuts, select a tougher grade or a larger corner radius; for delicate contours or close tolerances the 0.2 mm corner radius delivers the controlled engagement required. For questions about exact holder compatibility, insert stacking or recommended cutting data, Metav Werkzeuge can provide tailored guidance and cutting recommendations.

FAQ

Is this insert suitable for finishing steel?
Yes. The TPMT090202 AT9530 insert is formulated for finishing and light machining of steel, emphasising surface quality and uniform wear.

Which holders accept this TPMT insert?
Compatibility is determined by ISO form, relief angle (11°), tolerance class, fastening type, size and thickness; the TPMT shape fits holders designed for the TPMT090202 format.

What is the corner radius and why does it matter?
The corner radius is 0.2 mm; a smaller radius reduces cutting forces and supports finer surface finishes during finishing passes.

Does the insert have a mounting hole and seating feature?
Yes. The insert is supplied with a cylindrical hole and a single‑side countersink (40°–60°) for reliable seating and clamping.

Is this grade recommended for roughing or heavy interrupted cuts?
No. The AT9530 cermet grade is optimised for finishing and light turning; for heavy roughing, a tougher or specially designated roughing grade should be chosen.
