CPMT090304 AT9530 Turning insert (CPMT 090304 AT9530) — Tungaloy, coated cermet, 11° clearance

The CPMT090304 AT9530 is an ISO‑norm indexable turning insert in rhombic form, designed for finishing and light turning of steel with a focus on superior surface finish and uniform wear.

• Coated cermet grade AT9530
• Optimised for finishing operations
• ISO rhombic 09 size, 11° clearance
• Cylindrical hole with single‑side countersink

Achieving consistently superior surface finish and wear behaviour

The insert’s core advantage is its AT9530 grade: a coated cermet designed for finishing and light turning of steel. The composition and coating combine a low built‑up edge tendency with even abrasive wear, which helps to maintain a fine and repeatable surface finish over longer tool life. With a fine 0.4 mm nose radius the geometry supports delicate profile detail and improved part aesthetics while limiting vibration when run at appropriate feeds and speeds. For operations where part appearance and dimensional stability are priorities, this cutting geometry reduces rework and inspection cycles through predictable performance.

Secure seating and straightforward integration into ISO systems

Built to ISO standards, the plate’s rhombic form and the mounting arrangement with a cylindrical hole plus single‑side countersink (40°–60°) make it compatible with a wide range of external holders and boring bars that accept 09 size rhombic inserts. The 11° clearance angle reduces rubbing on the flank face and helps preserve the cutting edge under light finishing feeds. When selecting a holder, match form, clearance, tolerance class, fastening method, size and thickness as these determine full compatibility. Correct clamping and the use of the specified washer/klemmsatz and screw torque lead to reliable repeatability and reduced index‑to‑index variance during production.

Productivity benefits and choice guidance for finishing steel

Choosing a coated cermet like AT9530 for finishing means a balance between high surface quality and tool life: cermets often outperform uncoated carbides in finish turning of steel by resisting built‑up edge and preserving edge form. The one‑sided chipbreaker facilitates predictable chip flow in finishing cuts while avoiding aggressive chip formation that can mar fine surfaces. For stable setups and light depths of cut the insert pays off through fewer tool changes and consistent workpiece quality. When uncertainty exists about grade selection, consult process engineers to match the AT9530 characteristics to the specific steel grade and machining parameters; small adjustments to feed and speed often unlock substantial improvements in finish and life.

FAQ

Is this insert compatible with standard ISO turning holders?
The CPMT090304 AT9530 indexable insert is manufactured to ISO geometry and will fit holders designed for rhombic 09 inserts when form, clearance and thickness are matched; refer to the holder’s specifications for compatible tolerance classes.

For which operations is this grade recommended?
The AT9530 coated cermet is intended for finishing and light turning of steel; the CPMT090304 insert provides improved surface finish and uniform wear in stable setups and reduced built‑up edge compared with some carbide options.

What are the key mounting features to check before use?
Ensure the holder accepts the rhombic 09 form, 3.18 mm plate thickness and the with‑hole fastening (cylindrical hole with single‑side countersink); correct clamping and the designated screw/underlay set preserve repeatability and tool life.
