DNMG150404 AT9530 Tungaloy indexable insert — 55° rhombic for turning, 0.4 mm radius

The DNMG150404 AT9530 is an ISO rhombic indexable insert for precision external and internal turning, optimised for fine and light finishing of steel.

• Coated cermet grade AT9530
• 55° rhombic geometry for versatile turning
• 0.4 mm corner radius for consistent surface finish
• Double-sided chipbreaker for longer tool life

High-precision finishing and predictable wear

The coated cermet grade AT9530 is formulated for finishing and light cutting of steel, focusing on an improved surface finish and even flank wear. Cermet-based grades combine hardness and heat resistance to reduce edge rounding during long runs; as a result, the cutting edge maintains form for a stable process and predictable component quality. This behaviour reduces the need for frequent edge changes and supports higher first-pass quality in serial production.

Geometry tuned for controlled cutting and superior surfaces

A 55° rhombic insert with a 0.4 mm corner radius offers a balance between strength and fine-edge definition. The rhombic shape and 0° clearance create a controlled cutting geometry that is well suited to finishing passes where micro-geometry governs the final tolerance and appearance. The double-sided chipbreaker provides consistent chip control on both edges, improving stability when light interruptions or variable section thicknesses occur, and helping to guard against poor surface texture or rework.

ISO compatibility for straightforward system integration

Supplied as an ISO-format indexable plate, the insert fits into standard toolholders when shape, clearance angle, tolerance class, fixing method, size and thickness match the holder specification. The ISO conformity simplifies the selection of holder, clamp set and replacement screws within existing tool systems. The plate thickness of 4.76 mm and the cylindrical hole enable secure clamping and repeatable positioning, so tool changes are quick and process repeatability is supported across shifts.

Benefits in production flow and application guidance

Using a finishing-oriented grade such as AT9530 reduces polishing and secondary operations for components requiring tight surface specifications. The insert geometry and chip control reduce thermal and mechanical stresses on the cutting edge, which translates into steadier cycle times and fewer process interruptions. Selection of the chipbreaker and grade should be matched to material, stability and cutting parameters to fully exploit the advantages of this insert in turning applications.

FAQ

What materials is this insert designed for?
The DNMG150404 AT9530 insert from Tungaloy is intended primarily for finishing and light machining of steel, where the AT9530 grade offers an emphasis on surface quality and uniform wear.

Is the DNMG150404 compatible with standard ISO holders?
Yes, the DNMG150404 conforms to ISO dimensions; compatibility depends on matching form, clearance angle, tolerance class, fixing method, size and thickness to the chosen holder.

How does the 0.4 mm corner radius affect results?
A 0.4 mm corner radius provides better edge strength than very small radii while still delivering a fine machined finish, making the insert suitable for controlled finishing passes.

Can the AT9530 grade be used for interrupted cuts?
The coated cermet AT9530 offers good edge stability for light interruptions, and the double-sided chipbreaker helps maintain chip control, though heavier interruptions may require a different grade or geometry.

What is the benefit of a double-sided chipbreaker?
A double-sided chipbreaker provides two usable cutting edges with consistent chip control on each side, extending insert utilisation and improving process reliability during turning operations.
