CPGT080204 NS9530 Tungaloy turning insert — ISO rhombic 80° · uncoated cermet

The CPGT080204 NS9530 is an ISO rhombic turning insert designed for finishing turns on steel, offering a sharp cutting edge and predictable performance in continuous cuts.

• ISO rhombic insert CPGT 080204, 80° geometry
• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge for low cutting forces
• With central hole and 40°–60° countersink

Consistent finishing for steel components

The uncoated NS9530 grade is optimised for finishing of steel, delivering low cutting forces and an acute cutting edge that reduces workpiece distortion during light-pass turning. The rhombic 80° geometry, paired with a 0.4 mm corner radius, promotes stable contact conditions and a high-quality surface texture; this is particularly beneficial where dimensional accuracy and surface integrity are critical. The material combination of the cutting grade ensures a narrow range of chip formation, reducing vibration and improving repeatability in serial production.

Process reliability and predictable tool life

A finishing-oriented cermet like NS9530 is engineered for continuous cuts and small depths of cut, where the focus is on surface finish and edge sharpness rather than heavy metal removal. The sharp edge and the single-sided chipbreaker reduce built-up edge and lower cutting forces, which supports consistent part quality and predictable tool wear. Where process stability and consistent results are required, the insert’s geometry and grade contribute to reduced rework and higher first-pass yield.

Compatibility and mounting for swift index changes

As an ISO plate, compatibility with the clamping system depends on form, relief angle, tolerance class, mounting, size and thickness. The system typically comprises an ISO turning insert, a matching external holder or boring bar, a locating pad or clamping kit and replacement screws for rapid changeovers. The central hole with a cylindrical bore and one-sided countersink (40°–60°) ensures secure seating and repeatable positioning in standard clamping systems, enabling straightforward indexing and minimal fixture adjustment time.

Practical recommendations for productive turning

For finishing passes, select a stable holder and minimise overhang to exploit the low cutting forces of the cermet grade; the 11° relief angle and sharp edge favour continuous cuts with small depths of cut. The single-sided chipbreaker and the rhombic plate form are suited to unobstructed chip flow in common steel turning scenarios. Match the chipbreaker and the insert grade to the workpiece stability and machining strategy to achieve the best compromise between surface finish and tool life. If specific cutting parameters are required, consult the technical datasheet to align speeds and feeds with machine capability and part requirements.

FAQ

What materials is this insert intended for? The insert with grade NS9530 is intended primarily for finishing of steel; the cutting concept is optimised for continuous cuts and small depths of cut.

How does the CPGT080204 geometry affect machining? The rhombic 80° geometry gives a versatile cutting edge orientation that supports stable contact and good surface finish during finishing operations with low cutting forces.

Is the insert suitable for unstable setups or long overhangs? The CPGT080204 NS9530 insert is designed for situations favouring low cutting forces and sharp edges; for long overhangs or unstable setups, a more robust grade or geometry should be considered to maintain process security.

What clamping elements are required for installation? Installation requires a compatible ISO holder or boring bar, locating pad or clamping kit, and the correct replacement screw; the central hole with countersink ensures repeatable seating.
