DCGT 11T302 AT9530 indexable insert for turning (rhombic, 55°) by Tungaloy

The DCGT 11T302 AT9530 is an ISO-compliant, rhombic turning insert designed for finishing and light machining of steel, optimised for surface quality and even wear.

• Coated cermet grade AT9530 for superior surface finish
• 55° rhombic geometry for precise turning engagement
• 0.2 mm corner radius for consistent, fine edges
• Cylindrical hole + 40°–60° countersink for secure clamp

Enhanced finishing and consistent tool life for turning processes

The combination of a coated cermet grade and a compact geometry delivers measurable improvements in surface quality and tool life during finishing cuts. The AT9530 grade is formulated to reduce adhesion and provide even wear, which helps maintain consistent component tolerances across a production run. As an ISO-format cutting solution, this insert supports predictable machining results when matched with the correct holder, minimising process variation and reducing rework. The result is a reliable finishing performance that supports efficient shop-floor throughput.

Secure clamping and ISO compatibility for reliable setup

Compatibility with holders is determined by form, clearance angle, tolerance class, clamping method, size and thickness; this insert adheres to ISO norms to support straightforward integration. The cylindrical hole with a one-sided countersink (40°–60°) provides positive seating and stable clamping, while the 55° rhombic shape balances axial engagement and chip evacuation. With a thickness of 3.97 mm, a nominal size of 11, and a 0.2 mm corner radius, the geometry is tailored to finishing and light turning operations where stability and repeatability are required.

Improved productivity through material engineering and chip control

The cutting concept combines a carbide substrate with a coated cermet top layer to obtain both toughness and a fine cutting edge. Cermet offers a ceramic-rich surface that resists built-up edge formation and promotes a high-quality surface finish, while the underlying carbide provides core strength. The single-sided chipbreaker design supports controlled chip formation during low-to-moderate feed finishing, which reduces the risk of edge damage and shortens secondary operations such as deburring. This balance of edge quality and chip control translates into higher first-pass yield and more consistent productivity.

FAQ

Which materials are suitable for this insert?
The insert is optimised for finishing and light machining of steel; the AT9530 coated cermet promotes high surface quality when used on typical steel grades.

What holder characteristics are required for correct use?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; holders matching ISO DCGT11T302 geometry and a secure clamping seat for the cylindrical hole are recommended.

How does the AT9530 grade improve surface finish?
The AT9530 coating reduces adhesion and promotes uniform wear, while the cermet surface helps form a fine edge that produces improved surface finish in finishing operations.

Is the insert suitable for heavy roughing?
This insert is designed for finishing and light machining; for heavy roughing, a different geometry or tougher grade would be more appropriate.
