SPMT090304 GT9530 indexable turning insert — coated cermet, 0.4 mm corner radius, for turning (Tungaloy)

SPMT090304 GT9530 is a square ISO indexable insert designed for external and internal turning, providing high-quality finishing and improved tool life under stable machining conditions.

• Coated cermet grade GT9530
• ISO square format 09, 3.18 mm thick
• 0.4 mm corner radius for fine finishing
• One-sided chipbreaker, with central hole

Precise finishing through a wear-resistant coated cermet

The coated cermet grade GT9530 provides a targeted balance between wear resistance and edge sharpness, making it particularly suited for finishing and light universal operations on steel. The microstructure of the cermet substrate and the applied coating extend effective cutting life while preserving a sharp cutting edge; this yields consistent surface quality and reduces the need for rework. For production runs where surface integrity and dimensional stability are priorities, the coated cermet composition minimises built-up edge and maintains performance over longer tool cycles.

Reliable fit and stable clamping for repeatable results

This ISO-design insert conforms to standard geometries so that compatibility with holders is determined by form, clearance angle, tolerance class, fastening and thickness. The 11° relief angle and the central hole with cylindrical seat plus single-sided countersink (40°–60°) ensure a secure and repeatable mounting interface. A plate thickness of 3.18 mm and the square 09 size give robust support in the pocket, while the defined 0.4 mm corner radius helps control cutting forces. Together, these characteristics improve process stability and simplify tool-change procedures for predictable component quality.

Application guidance and productivity advantages in turning

Designed for turning operations, the insert is applicable for both external and internal machining where a fine finish is required. Selecting the matching one-sided chipbreaker and the GT9530 grade according to workpiece material and machine stability results in optimised chip control and longer intervals between indexings. In practice, this leads to higher throughput for finished components and a lower cost per part in stable setups. The compatibility with common ISO holders and the standardised geometry also supports fast tool replacement and effective stock management.

FAQ

What materials is this insert suited for?
The GT9530-coated cermet insert is optimised for steel finishing operations; select the chipbreaker and machining parameters to match component material and stability.

How does the GT9530 grade improve surface finish?
GT9530's combination of cermet substrate and coating maintains a sharp cutting edge and resists built-up edge, which helps produce a consistent, fine surface finish during turning.

Is the SPMT090304 compatible with standard ISO holders?
Yes, the SPMT090304 follows ISO geometry; compatibility depends on holder form, clearance angle, tolerance class, fastening and thickness.

What benefit does the 0.4 mm corner radius provide?
A 0.4 mm corner radius reduces cutting stress while enabling precise finishing, helping to achieve dimensional accuracy and good surface integrity.

Can this insert be used for heavy roughing?
This insert is specified as a wear-resistant finishing to light universal grade; for heavy roughing, a different geometrical form or a tougher grade should be selected.
