SCMT 09T304 AT9530 Drehen — Tungaloy turning insert, coated cermet, 0.4 mm radius

The SCMT09T304 AT9530 Tungaloy insert is a coated cermet finishing grade designed for external and internal turning of steel, offering consistent wear behaviour and high surface quality in light machining operations.

• Coated cermet grade AT9530
• Optimised for finishing on steel
• 0.4 mm corner radius for fine detail
• ISO square insert, 09 size, with hole

Superior surface quality through a cermet finishing grade

The AT9530 grade combines a coating with a cermet substrate to deliver a stable cutting edge and reduced built-up edge during finishing passes. This results in a noticeably improved surface finish while extending predictable tool life under light cutting conditions. The moderate toughness of the grade helps maintain edge integrity where minimal material removal and high dimensional accuracy are required, making it particularly suitable for applications where consistent part appearance and reduced rework are priorities.

Precise fit and secure clamping for predictable machining outcomes

Compatibility with holders depends on form, relief angle, tolerance class, fastening method, size and thickness; this insert is ISO‑standardised for straightforward selection. The square shape (09 size) with a 0.4 mm corner radius, 3.97 mm thickness and a 7° relief angle ensures correct seating and repeatable geometry. The insert features a cylindrical hole with a one‑sided countersink (40°–60°) to secure clamping and accurate locating; such details reduce vibration and improve repeatability in both external and internal turning setups.

Practical selection and machining guidance for efficient processes

For finishing and light turning operations on steel, select the AT9530 grade with the one‑sided chipbreaker provided to control chips and favour consistent cutting forces. The combination of a coated cermet and a small corner radius supports low cutting forces and fine edge definition, which helps to achieve dimensional tolerance quickly and reduce downstream polishing. Where higher material removal is required, choose a tougher grade; for superior surface integrity in final passes the AT9530 offers a clear balance between surface quality and wear stability.

FAQ

Which materials is this insert suitable for?
The SCMT09T304 AT9530 Tungaloy insert is optimised for finishing and light machining of steel, offering enhanced surface quality and consistent wear under temperate cutting conditions.

What does the 0.4 mm corner radius mean for part finish?
A 0.4 mm corner radius on the insert produces finer edge transitions and improved surface integrity during finishing cuts, reducing the need for secondary polishing when using the AT9530 grade.

How does the hole and countersink affect clamping?
The cylindrical hole with one‑sided countersink (40°–60°) ensures reliable seating and central clamping, which improves locating accuracy and reduces vibration for repeatable turning operations with the SCMT09T304.

Can this insert be used for internal turning?
Yes, the insert’s geometry and stable wear behaviour make it suitable for both external and internal turning when paired with an appropriate holder and correct clamping.

What are the key dimensional parameters to check for holder compatibility?
Verify ISO designation, shape (square), thickness 3.97 mm, relief angle 7°, size 09 and hole style; these determine correct fit and secure clamping for the insert.
