CPMT090304 GT9530 — ISO turning indexable insert, coated cermet (Tungaloy)

The CPMT090304 GT9530 is a rhombic ISO insert for turning, designed for finishing to light universal operations on steel where excellent surface quality and extended wear resistance are required

• Coated cermet grade GT9530
• Rhombic ISO insert CPMT 090304
• 0.4 mm corner radius for fine finish

Reliable surface finish with wear-resistant grade

The combination of a coated cermet cutting material and a small 0.4 mm corner radius delivers consistent surface quality in stable turning setups. The GT9530 grade is formulated for high wear resistance during finishing and light general-purpose cuts in steel; this reduces the frequency of tool changes and helps maintain dimensional consistency across production runs. Where surface integrity is critical, the insert’s geometry and coating work together to lower flank wear and preserve the cutting edge for longer intervals, supporting steady cycle times and predictable component quality.

Precise geometry for predictable tool mounting

Designed to the ISO turning insert family, the rhombic shape with an 80° included angle and 11° relief ensures compatibility with standard external holders and boring bars. The ISO conformity means that form, relief angle, tolerance class, fastening method, size and thickness determine holder fit; this makes changeovers straightforward and reduces setup time on multi-shift lines. The insert’s cylindrical hole with single-sided countersink (40°–60°) enables secure clamping and stable seating, translating into reduced vibration and improved repeatability in precision turning operations.

Chip control and process stability for productive turning

A one-sided chipbreaker and the optimised GT9530 composition focus on controlled chip formation under stable cutting conditions, which enhances process reliability and operator safety. In practice, the chip control design supports consistent swarf evacuation and helps avoid re-cutting or surface defects during finishing passes. The 3.18 mm thickness and ISO size designation contribute to mechanical robustness, allowing the insert to withstand moderate cutting forces while preserving the fine edge required for high-quality finishes on steel components.

FAQ

What materials is this insert best suited for?
The GT9530-coated cermet is optimised for machining steel in finishing and light universal turning operations; the CPMT090304 insert performs best under stable cutting conditions where surface finish and longer tool life are priorities.

Is the insert compatible with standard ISO holders?
Yes. The CPMT090304 conforms to ISO turning-insert standards; compatibility depends on form, relief angle, tolerance class, fastening, size and thickness, so it fits standard external holders and boring bars designed for CPMT geometry.

How is the insert secured to the holder?
The insert features a cylindrical hole with a single-sided countersink (40°–60°) for secure clamping; this mounting style provides stable seating and supports repeatable positioning during tool changes.

Can this insert be used for internal turning as well as external turning?
The insert is suitable for both external and internal turning applications, provided the holder and setup meet the ISO specifications and the cutting conditions remain within the stable range recommended for finishing work.

What is the article number and manufacturer SKU for ordering?
The article number is 6998320 and the manufacturer SKU is TUN6998320 for the Tungaloy CPMT090304 GT9530 turning insert.
