CPMT 090308 AT9530 turning insert by Tungaloy — coated cermet for fine finishing

CPMT 090308 AT9530 is an ISO‑normed turning insert designed for finishing and light machining in steel applications, offering a balanced geometry for stable cutting and superior surface quality.

• Coated cermet AT9530
• ISO CPMT090308 rhombic insert
• 11° clearance for stable cutting
• 0.8 mm corner radius for fine finish

Achieving consistent surface quality with a specialised grade

The combination of a coated cermet AT9530 cutting material and a precision geometry targets finishing and light machining where surface integrity matters. The coating promotes even wear, which reduces the frequency of index changes and maintains a consistent profile across batches. For operators aiming for reproducible part finish in serial work, this results in fewer re‑works and more predictable process windows. The insert’s geometry supports low‑vibration engagement, translating the material advantages into tangible throughput improvements without sacrificing finish quality.

Secure clamping and ISO compatibility for reliable set‑ups

Manufactured to ISO specifications, the CPMT 090308 form requires a holder that matches the insert’s shape, clearance angle, tolerance class, fastening method, size and thickness to ensure repeatable positioning. The insert’s 11° clearance and standardised seat dimensions simplify integration into existing toolholders when the correct holder pocket and clamp are used. Correct matching reduces runout and improves tool life, while the standard format allows straightforward replacement and inventory management across multiple machines.

Geometry and chip control engineered for finishing passes

The rhombic shape with a 0.8 mm corner radius and 3.18 mm thickness combines rigidity with a fine cutting edge suitable for finishing cuts. The design includes a cylindrical hole with a single‑sided countersink (40°–60°) to ensure secure seating and clamp stability. A single‑sided chipbreaker assists with controlled chip formation during light cuts, which supports consistent surface texture and reduces the risk of edge build‑up on the insert. Together, these features make the insert well suited to precision external and internal turning operations with a focus on surface finish.

Practical selection and application guidance for efficient machining

Select the chipbreaker profile and the AT9530 grade to match material, machining method and component stability: choose this coated cermet for steels where finishing and uniform tool wear are priorities. The insert is intended for turning operations where gentle engagement and steady cutting conditions prevail; it performs especially well in finishing and light‑cut scenarios. For complex component set‑ups or where vibration control is critical, consult technical data or the supplier to ensure the correct holder and clamping components are specified to exploit the insert’s benefits fully.

FAQ

Is this insert suitable for finishing steel?
The CPMT 090308 AT9530 insert is optimised for finishing and light machining of steel, where the AT9530 coating promotes uniform wear and a superior surface finish.

Which toolholders are compatible with this insert form?
Compatibility requires an ISO‑compliant holder matching the insert form, clearance angle, tolerance class, fastening method, size and thickness—ensure the holder accepts the CPMT090308 geometry for secure seating.

What advantages does the AT9530 coating offer?
The AT9530 coated cermet provides even wear and stable cutting edges, supporting consistent part quality and extended intervals between indexing or replacement.

How is the insert mounted given the hole style?
The cylindrical hole with a single‑sided countersink (40°–60°) is intended for clamp or screw fastening together with an underlay; correct clamp selection ensures repeatable clamping and minimal runout for the Tungaloy insert (SKU 6773736‑Tungaloy).

Can this insert be used for internal turning operations?
Yes, the geometry and chip control of the CPMT090308 make it suitable for both external and internal turning when matched with the appropriate holder and stable set‑up.
