CPMT 080202 NS9530 indexable insert for turning by Tungaloy — uncoated cermet, rhombic 80° geometry

CPMT080202 NS9530 Tungaloy insert is an ISO‑standard indexable insert designed for precision turning and finishing of steel components, offering a sharp cutting edge and low cutting forces for continuous cuts and small depths of cut.

• Sharp uncoated cermet cutting edge
• Optimised for fine finishing on steel
• Rhombic 80° geometry, 0.2 mm radius
• Cylindrical hole with 40°–60° countersink

Consistent surface quality through a finishing‑oriented grade

The NS9530 grade is an uncoated cermet designed specifically for finishing operations on steel. Its inherently sharp edge and low cutting resistance produce high surface quality even at small feed and depth settings. Because the grade targets continuous cutting, it helps to reduce vibration and maintain a steady tool‑workpiece interaction, which leads to reproducible part quality and fewer rework cycles. This makes the insert particularly suitable where surface integrity and tight tolerances are required.

Geometry and ISO compatibility for reliable clamping

The rhombic 80° geometry combined with a 0.2 mm radius and 11° clearance supports stable engagement and predictable cutting forces. The insert follows ISO designation CPMT080202, so compatibility with ISO holders is governed by form, clearance angle, tolerance class, fixation method, size and thickness. Choosing holders matched to these parameters ensures correct seat and clamp pressure, minimising chatter and enabling repeatable tool changes without additional adjustment.

Practical application: efficient finishing on steel

For turning operations that prioritise finish, the single‑sided chipbreaker is adapted to small depths of cut and continuous feeds, helping to control chip flow and avoid surface disturbance. The insert’s characteristics translate to fewer passes to achieve the target finish and a reduced need for secondary polishing. When machining steel in finishing passes, select cutting values that favour the grade’s strengths—moderate cutting speed with low feed—to exploit the sharp uncoated edge and obtain consistent results.

Material behaviour and tool life considerations

Manufactured from a wear‑resistant carbide substrate and specified as an uncoated cermet, the insert balances a keen cutting edge with stable wear behaviour for finishing tasks. Cermet grades like NS9530 offer excellent surface finish potential and low built‑up edge tendency; however, their best performance appears under steady cutting conditions and with appropriate cutting data. Monitoring tool condition and using optimised feeds will extend useful life and maintain the desired component finish.

FAQ

What is the primary application for this insert?
The CPMT080202 NS9530 Tungaloy insert (SKU 6998454-Tungaloy) is intended for turning, with a focus on finishing operations on steel where a fine surface is required.

How does the single‑sided chipbreaker affect machining?
The single‑sided chipbreaker on this NS9530 grade promotes controlled chip formation during continuous cuts and small depths of cut, improving chip evacuation and surface consistency when using the CPMT080202 indexable insert.

Which holders are compatible with the insert?
Compatibility depends on the holder’s form, clearance angle, tolerance class, fixation and size; use holders designed for the ISO CPMT080202 geometry to ensure correct seating and clamping for the Tungaloy finishing insert.

What cutting data should be prioritised for best surface finish?
Prioritise moderate cutting speeds and low feeds for finishing with the NS9530 uncoated cermet; these settings reduce cutting forces and exploit the insert’s sharp edge for improved surface quality.
