CNMG 090408 GT9530 Tungaloy Turning Insert — Coated Cermet, 0.8 mm Corner Radius

CNMG 090408 GT9530 is an ISO-standard rhombic turning insert designed for precision external and internal turning in stable machining conditions

• Coated cermet grade GT9530
• ISO CNMG 090408 rhombic insert
• 0.8 mm corner radius for fine finishes
• Double-sided chipbreaker with cylindrical hole

Consistent surface quality and prolonged tool life

The GT9530 grade is a coated cermet engineered for low-wear finishing and light general-purpose turning where a high-quality surface finish matters. The combination of cermet chemistry and a tailored coating improves resistance to abrasive wear while maintaining sharp cutting edges; this results in fewer tool changes and more consistent part surfaces during series production. For operations where dimensional stability and surface integrity are priorities, the insert's polished edge geometry supports predictable cutting forces and smoother finish.

ISO standard geometry for simple toolholder selection

Supplied as an ISO CNMG 090408 format, the insert fits standard holders when shape, clearance angle, tolerance class, fastening method, size and thickness are matched. The rhombic form and central hole enable secure clamping on a wide range of external holders and boring bars. Stating the ISO designation simplifies procurement and ensures compatibility across tool systems, while the two-sided design provides economical indexable performance with repeatable seating and concentricity.

Precision geometry that promotes process stability

With a 0.8 mm corner radius, 4.76 mm thickness and an 80° approach angle, the geometry is tuned for stable cutting with reduced vibration and improved edge strength. The rake angle 0° offers a predictable cutting action across common steels, helping to maintain surface finish without excessive cutting forces. These features assist in achieving reproducible machining results, especially in applications where tool runout and fixture rigidity are controlled and where consistent tool life is essential for planning production cycles.

Practical system considerations and handling benefits

The insert forms part of a complete system: indexable plate, matching clamping kit or shim, fastening screws and the appropriate external holder or boring bar. The double-sided chipbreaker and cylindrical centre hole facilitate reliable seating and straightforward indexing, while the rhombic shape enables use in both external and internal turning. Operators benefit from reduced setup times and predictable replacement intervals, enabling smoother workflow planning and lower inventory complexity when using standard ISO formats.

FAQ

What materials is this insert best suited for?
The GT9530 grade is a coated cermet optimised for steel machining where good surface finish and extended life are required; it performs well in stable cutting conditions.

How many cutting edges are available per insert?
The double-sided geometry provides two usable cutting edges per indexable plate before regrinding or replacement is necessary.

How does the ISO CNMG 090408 designation help when selecting a holder?
ISO CNMG 090408 identifies the insert form and size so compatible holders can be selected based on shape, thickness (4.76 mm), clearance and clamping method to ensure correct fit and repeatability.

What benefit does the 0.8 mm corner radius provide?
A 0.8 mm corner radius balances edge strength with surface quality, reducing the risk of chipping while supporting finer surface finishes in finishing passes.

Is the GT9530 insert suitable for heavy roughing?
GT9530 is a wear-resistant finishing to light general-purpose grade; for heavy roughing, a tougher grade would be recommended to withstand higher mechanical loads.
