CNMG090404 AT9530 indexable turning insert for finishing, Tungaloy

The CNMG090404 AT9530 is an ISO-standard indexable insert designed for finishing and light turning of steel, optimised for excellent surface quality and even wear across the cutting edge.

• ISO-standard rhombic insert, 80° cutting angle
• Coated cermet grade AT9530 for high surface finish
• Double-sided chipbreaker, cylindrical hole
• 0.4 mm corner radius for fine finishing

High-quality finishing for steel components

The CNMG090404 AT9530 delivers a measured improvement in surface integrity thanks to its coated cermet composition and geometry. The AT9530 grade is formulated for Schlicht- and light machining of steel, emphasising a stable cutting edge and uniform wear patterns that reduce the need for rework. The 0.4 mm corner radius supports consistent part tolerance at finishing feeds, while the rhombic 80° geometry balances strength and access to external and internal contours. This combination results in fewer secondary operations and a predictable finish quality in serial production.

Greater process stability and extended tool life

A finishing-grade cermet offers higher hot hardness and reduced built-up edge compared with conventional carbides, which supports even wear and steady cutting forces during prolonged runs. The double-sided chipbreaker provides controlled chip formation at finishing parameters, lowering the risk of surface damage and minimising tool-change downtime. Such predictable behaviour contributes to improved uptime and a better cost-per-part ratio when used in precision turning applications.

ISO compatibility and practical system integration

The insert conforms to ISO indexing and is compatible with appropriate external holders or boring bars when matching form, clearance, tolerance class, fastening and thickness. The item includes a cylindrical hole for secure fastening and a plate thickness of 4.76 mm, with a relief angle of 0° suited to finishing geometries. The complete cutting system comprises the ISO insert, a matching holder or boring bar, the recommended underlay/clamp set and replacement screws; this modular approach simplifies inventory and reduces setup complexity on the shop floor.

FAQ

What materials is this insert best suited for?
The CNMG090404 AT9530 insert is optimised for finishing and light machining of steel; the AT9530 coated cermet grade emphasises surface quality and consistent wear when used on steel workpieces.

Is the insert indexable on both sides?
Yes, this indexable turning insert features a double-sided chipbreaker, allowing both sides to be used subject to proper indexing and secure clamping.

How does the 0.4 mm corner radius affect part finish?
A 0.4 mm corner radius helps produce finer surface finishes and supports tighter dimensional control during finishing passes when using the CNMG090404 AT9530 geometry.

Which holder types are compatible with this ISO insert?
Compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; the ISO-standard CNMG090404 shape fits standard external holders or boring bars designed for rhombic 80° inserts.

What advantages does the AT9530 coating provide?
The AT9530 coated cermet grade improves surface integrity and promotes even wear over the cutting edge, which benefits finishing operations and reduces the frequency of tool changes.
