DCMT 11T302 AT9530 turning insert for finishing – Tungaloy

The DCMT11T302 AT9530 is an ISO rhombic turning insert engineered for finishing and light machining of steel, prioritising excellent surface finish and steady wear behaviour.

• ISO rhombic insert DCMT 11T302
• AT9530 coated cermet for fine finishes
• 0.2 mm corner radius for precision profiles

Improve surface quality with a coated cermet grade

The coated cermet grade AT9530 is tailored for finishing and light-cutting operations on steel, emphasising a superior surface finish and uniform wear over the tool life. As a finishing grade, the microstructure and coating combination support stable cutting edges at the lower cutting depths typical of final passes. This results in fewer rework cycles and a predictable wear pattern, which helps maintain part tolerances and reduces inspection effort. The paragraph focuses on measurable benefits rather than broad claims, highlighting why a fine-grade insert is appropriate for high‑quality turned surfaces.

Precision geometry for reliable seating and repeatability

The insert features a rhombic form with a 55° geometry, a 0.2 mm corner radius and a 7° clearance angle, with a plate thickness of 3.97 mm and a nominal size of 11. The mounting includes a cylindrical hole with a single-sided countersink (40°–60°) to suit standard clamping systems. Compatibility with the toolholder is determined by form, clearance angle, tolerance class, fastening, size and thickness; matching these parameters ensures accurate seating, repeatable indexation and consistent chip flow. Such geometry data are decisive for fixture selection and process planning in production environments.

Application guidance to increase productivity and predictability

Intended for turning where surface integrity is a priority, the insert pairs with a matching single-sided chipbreaker and the correct holder to balance chip control and stability. Selecting the appropriate chipbreaker and grade according to workpiece material and machine stability improves cycle consistency and reduces scrap rates. If pockets of hard inclusions or heavy interrupted cuts are expected, the grade’s characteristics suggest limiting depth of cut and favouring finishing passes; for more aggressive material removal, consider alternative grades designed for roughing. Practical guidance and process parameters help integrate the insert into existing turning operations with minimal trial-and-error.

FAQ

Is this insert suitable for machining steel? Yes. The DCMT11T302 AT9530 Tungaloy turning insert is designed specifically for finishing and light machining of steel, with a focus on surface quality and even wear.

What is the corner radius and how does it affect the component? The corner radius is 0.2 mm; a smaller radius like this helps produce precise profiles and fine surface finishes while keeping cutting forces moderate.

Which holder characteristics must match the insert? Holder compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; ensure the toolholder matches these parameters for the insert to seat and index correctly.

Can this insert be used for roughing operations? This grade is optimised for finishing and light machining; for heavy roughing, a different, more robust grade designed for higher material removal rates is recommended.

What are the mounting details for the insert? The plate has a cylindrical hole with a single-sided countersink (40°–60°) and a thickness of 3.97 mm, intended for standard ISO clamping systems and secure seating.
