DCMT11T304 AT9530 ISO rhombic turning insert for finishing, Tungaloy

The DCMT11T304 AT9530 is an ISO rhombic turning insert designed for finishing and light turning of steel with a focus on surface quality and predictable wear

• ISO rhombic insert, DCMT form
• Coated cermet grade AT9530
• 0.4 mm nose radius for fine finishes
• 7° clearance; cylindrical hole with countersink

Achieve superior surface finish with a coated cermet grade

The insert employs a coated cermet specification AT9530, developed for finishing and light machining of steel where surface integrity matters. The composition balances ceramic hardness and metallic toughness to reduce flaking and promote uniform wear across the cutting edge. This results in longer intervals between index changes and a consistently improved surface finish, especially on external and internal turning operations that demand close tolerances and fine surface texture. The cermet coating also supports stable performance at finishing feeds and moderate cutting speeds.

Confident compatibility with ISO toolholder systems

Compatibility with toolholders is governed by geometric and dimensional standards: insert form, clearance angle, tolerance class, attachment method, size and thickness. The rhombic insert follows established ISO dimensions so it mates reliably with matching clamping systems. Correct pairing ensures the insert seats correctly and the specified clearance angle is maintained, reducing chatter and improving reproducibility. Where vibration dampening or added rigidity is required, selecting an appropriate external holder or boring bar and a correctly rated clamping set will preserve edge life and process stability.

Geometry and clamping designed for stable finishing cuts

The rhombic plate with a 55° principal angle and a 0.4 mm nose radius gives a precise contact geometry that favours fine cutting action and low cutting forces. The plate thickness of 3.97 mm contributes axial and radial rigidity when clamped in a suitable holder, while the single-sided chipbreaker helps control chip flow for finishing feeds. The insert is manufactured with a cylindrical hole and a one-sided countersink (40°–60°) to ensure secure and repeatable clamping; this design supports predictable cutting behaviour and eases index changes during production.

Practical selection and system notes for efficient machining

For reliable outcomes, choose a chipbreaker and grade matched to workpiece material, machining style and machine stability. The grade AT9530 is optimised for consistent edge condition during finishing of steel; a different chipbreaker or a more robust grade should be selected for higher stock removal or interrupted cuts. The full system comprises the ISO insert, a compatible external holder or boring bar, and the necessary shim/clamp set plus replacement screws to complete the assembly. If part geometry, surface finish or cycle time targets are critical, a short validation run with the insert in the intended holder will clarify the final parameter window for feeds and speeds.

FAQ

What materials is this insert best suited for?
The DCMT11T304 AT9530 Tungaloy insert (SKU 6762156-Tungaloy) is intended primarily for steel finishing and light turning, where the coated cermet grade AT9530 delivers improved surface quality and controlled wear.

Which toolholders will accept this insert?
Compatibility follows ISO standards: the insert fits holders that match the DCMT form, size 11, thickness 3.97 mm, clearance angle 7° and the specified tolerance class; always verify form and attachment type before assembly.

What nose radius and geometry should be expected for fine finishing?
This insert features a 0.4 mm nose radius and a rhombic geometry that favour fine surface finishes and low cutting forces in finishing operations.

Does the insert include a chipbreaker and what is its effect?
Yes — the insert has a single-sided chipbreaker designed to promote consistent chip control and steady surface quality during finishing feeds.

Is the insert suitable for heavy roughing or interrupted cuts?
The DCMT11T304 AT9530 Tungaloy insert is optimised for finishing and light machining; for heavy roughing or highly interrupted cuts a more robust grade and different chipbreaker geometry are recommended.
