CPMT 080204 AT9530 CPMT rhombic ISO turning insert for finishing — Tungaloy

The CPMT080204 AT9530 is a rhombic ISO turning insert designed for finishing and light turning of steel, combining a coated cermet cutting grade with a one-sided chipbreaker for stable, high-quality results

• Coated cermet AT9530 for superior surface finish
• Rhombic ISO insert CPMT080204 with 11° clearance
• 0.4 mm corner radius for fine finishing
• Cylindrical hole with single-sided countersink

Consistent finishing and why the cermet grade matters

The coated cermet AT9530 is optimised for finishing and light machining of steel, offering a fine-grain cutting surface that promotes excellent surface finish and uniform wear across the cutting edge. Cermet combines ceramic hardness with a metallic binder to resist abrasive wear while preserving edge integrity; the applied coating further improves adhesion and reduces flank wear. For operations where appearance and dimensional consistency are priorities, this combination reduces rework and enhances process stability.

Precision geometry that supports reliable toolholding and repeatable results

The rhombic ISO geometry with an 11° clearance and a 0.4 mm corner radius is intended for controlled contact between tool and workpiece during finishing passes. The insert’s cylindrical hole with single-sided countersink (40°–60°) provides secure clamping and precise seating in compatible holders; compatibility is determined by geometry, clearance angle, tolerance class, fastening method, size and thickness. The compact 2.38 mm thickness and size designation 08 keep the insert suitable for finishing where limited overhang and good rigidity are required.

Practical process benefits and selection guidance

A one-sided chipbreaker tuned to finishing reduces built-up edge and produces predictable chip formation under light cut regimes, so cycle consistency improves and surface quality becomes more repeatable. Select the chipbreaker and grade to match workpiece stability and machining parameters: when higher cutting speeds and steady feeds are possible, the coated cermet choice helps extend effective tool life and maintain edge sharpness. For operators new to cermet grades, reducing feed slightly compared with conventional carbide finishing settings often yields the best combination of life and finish.

Compatibility, installation and shop-floor considerations

The ISO-standard designation simplifies procurement and replacement; still, ensure matching of form, free clearance, tolerance class, fastening and thickness when pairing the insert with external holders or boring bars. The rhombic form and the countersunk hole require a holder designed for CPMT-style inserts; correct seating prevents micro-movements that can degrade surface finish. For process documentation, note the grade designation, insert geometry and holder type to reproduce optimal cutting conditions across batches.

FAQ

What materials is this insert intended for? The CPMT080204 AT9530 is specified for finishing and light machining of steel using a coated cermet cutting grade.

How does the 0.4 mm corner radius affect the finish? A 0.4 mm corner radius helps produce a finer surface finish while maintaining adequate edge strength for finishing passes with consistent feed and depth.

Which holders are compatible with this ISO rhombic insert? Compatibility depends on holder form, free clearance, tolerance class, fastening, size and thickness; holders designed for CPMT-style ISO inserts are required.

What is the purpose of the single-sided countersink on the hole? The cylindrical hole with a single-sided countersink (40°–60°) ensures secure seating and correct axial positioning in the clamping system for repeatable results.

Can this grade be used at higher cutting speeds? The coated cermet AT9530 is optimised for finishing; moderate increases in cutting speed can be beneficial, but optimal parameters depend on workpiece stability and machine rigidity
