SPMT 090304 AT9530 — Tungaloy turning insert for finishing

SPMT 090304 AT9530 is an ISO-format turning insert designed for finishing and light machining on steel, combining a coated cermet grade with a small corner radius for excellent surface quality

• Coated cermet grade AT9530
• Optimised for finishing of steel
• ISO SPMT090304, 0.4 mm corner radius
• Cylindrical hole with 40°–60° countersink

Predictable productivity through controlled wear

The insert delivers steady performance by pairing a coated cermet formulation with a geometry tuned for finishing. The AT9530 grade is developed to promote uniform wear patterns, which reduces the frequency of unscheduled index changes and supports predictable cycle times. With a fine cutting edge and 0.4 mm corner radius, the component is suited to operations where surface integrity and repeatability matter most. This balance of wear resistance and edge stability contributes directly to higher throughput on medium- to high-volume turning tasks.

Superior surface finish in light machining

For jobs that prioritise surface quality over heavy metal removal, the insert’s geometry and coating work together to produce consistently low roughness values. The single-sided chipbreaker aids chip control in finishing cuts while the insert’s small corner radius helps minimise waviness on external and internal profiles. As a result, finishing cycles often require fewer downstream operations, improving overall process efficiency and reducing handling time.

Easy integration with ISO tool systems

This indexable plate follows ISO form and dimensional standards, allowing straightforward use with compatible holders and boring bars. The SPMT090304 designation and square plate form simplify selection for shops running standard toolholders; compatibility is determined by form, clearance angle, tolerance class, fixing method, size and thickness. The insert’s cylindrical hole with a single-sided countersink (40°–60°) ensures secure clamping and repeatable seating in the pocket, improving stability during fine turning.

Material suitability and technical advantages

Manufactured from cemented carbide and finished with the AT9530 coating, the insert is optimised for steel finishing and light turning. The plate thickness of 3.18 mm and 11° clearance support stable cutting conditions while maintaining a sharp cutting edge for high-quality surfaces. The square 09 size and included angle of 90° make the insert versatile for external and internal profiles where access and rigidity are factors. The combination of substrate and coating gives a compromise between toughness and wear resistance tailored to fine turning.

FAQ

What materials is this insert intended for?
The SPMT090304 AT9530 insert is optimised for finishing and light machining of steel using the AT9530 coated cermet grade.

Is the insert compatible with standard ISO holders?
Yes; the insert follows ISO dimensions for SPMT090304 plates and is compatible provided the holder matches form, size, thickness and fixing method.

How does the 0.4 mm corner radius affect finishing?
A 0.4 mm corner radius on this insert reduces surface waviness and helps achieve finer finishes on external and internal turning profiles.

What clamping interface does the insert require?
The insert has a cylindrical hole with a single-sided countersink (40°–60°) for secure mounting and repeatable seating in the pocket.

Which feature of the AT9530 grade improves process stability?
The AT9530 coated cermet promotes even wear and maintains edge integrity in finishing cuts, supporting consistent process stability
