• 0.4 mm corner radius for fine finish
• Double-sided geometry, cylindrical hole

Consistent finishing and extended tool life

The GT9530 coating is a wear‑resistant cermet grade developed for finishing and light universal turning of steel under stable cutting conditions. Its composition provides a durable cutting edge that reduces flank wear and helps maintain a consistent surface finish over longer tool life. For production runs where repeatability and reduced rework are priorities, this indexable insert delivers reliable edge performance and fewer interruptions for insert changes, improving overall process efficiency.

Precise geometry for stable clamping and accuracy

The ISO designation and rhombic shape ensure straightforward matching with ISO‑compliant toolholders; the insert’s 80° included angle and 0° relief make for a predictable cutting geometry that supports dimensional accuracy. The presence of a cylindrical hole facilitates secure clamping with standard screws and clamping sets, while the double‑sided design offers two usable cutting edges per index, optimising tool utilisation and inventory efficiency without compromising stability.

Practical dimensions that support fine finishing

A 0.4 mm corner radius gives a balance between edge strength and the ability to generate a fine machined surface, especially when paired with modest feeds and stable setups. The plate thickness 4.76 mm and size 12 mm provide sufficient rigidity for finishing passes while keeping the insert compatible with a wide range of holders. The double‑sided chipbreaker geometry assists controlled chip formation, reducing the likelihood of built‑up edge and supporting consistent surface quality during finishing operations.

Selection logic and process benefits

Choosing the GT9530 grade for finishing turning reduces downstream grinding or polishing by delivering superior as‑turned surfaces under the right conditions. The coated cermet grade is particularly economical where longer intervals between index changes are required, resulting in higher effective cutting time and lower process cost per component. For applications requiring stable cutting parameters and good surface integrity, this ISO turning insert is a practical option that helps maintain throughput and part quality.

FAQ

Which materials is the GT9530 grade optimised for? The GT9530 grade is formulated for steel machining in finishing and light universal turning; the CNMG 120404 GT9530 insert performs best under stable cutting conditions where good surface finish is required.

Is the insert indexable and how many cutting edges are available? The CNMG 120404 GT9530 is double‑sided and indexable, providing two usable cutting edges per side depending on clamping and orientation, which extends effective tool life.

How does the 0.4 mm corner radius influence results? A 0.4 mm corner radius increases edge strength while still allowing a fine surface finish; it reduces the risk of edge chipping compared with very small radii and supports consistent part quality in finishing passes.

What determines holder compatibility for this insert? Holder compatibility for this ISO insert is determined by form, relief angle, tolerance class, mounting method, size and thickness; matching the ISO specification ensures secure clamping and accurate cutting geometry.

Is this insert suitable for heavy roughing operations? The GT9530 is a wear‑resistant finishing to light universal grade and is not primarily intended for heavy roughing; for heavy material removal a more robust grade and different geometry would be recommended.
