CPMT 080208 NS9530 Tungaloy turning insert — ISO CPMT, uncoated cermet, 80°

The CPMT080208 NS9530 Tungaloy insert is an ISO-standard rhombic turning insert designed for finishing cuts on steel, offering a sharp cutting edge and consistent surface quality.

• ISO rhombic insert, 80° cutting geometry
• NS9530 uncoated cermet, finishing grade
• Sharp cutting edge for superior surface finish
• 0.8 mm corner radius, with central hole & countersink

Optimised finishing for steel components

The insert is engineered as a finishing grade for steel, utilising the NS9530 uncoated cermet to achieve a sharp cutting edge and low cutting forces. These properties reduce vibration during continuous cuts and encourage a stable cut formation, which in turn leads to a consistent surface finish and less rework. The combination of a fine cutting geometry and the cermet cutting material makes this solution especially effective where small depths of cut and high-quality part appearance are required.

Secure seating and predictable fit in holders

Compatibility with clamping systems is determined by the insert’s form, relief angle, tolerance class, attachment style, size and thickness. The rhombic 80° geometry and 11° relief angle allow predictable seating in ISO-compatible holders and boring bars. The insert’s central hole with a cylindrical bore and a one-sided countersink (40°–60°) ensures repeatable clamp engagement and reliable orientation, supporting steady production runs and reducing downtime associated with misfits.

Geometry and dimensions that support consistent performance

With a 0.8 mm corner radius and a 2.38 mm thickness, the insert balances edge strength with the finesse required for finishing operations. The rhombic form distributes cutting loads efficiently, while the nominal 80° cutting angle provides a compromise between strength and accessibility on profiles. These dimensional choices contribute to process stability and predictable tool life when paired with the appropriate holder and cutting parameters.

Selecting this grade for production reliability

The uncoated cermet composition of this grade favours continuous cutting and small feeds, delivering excellent surface quality without the need for additional coating layers. Where process reliability and repeatable part quality matter most, this insert’s specification supports manufacturers aiming for productivity and surface integrity.

FAQ

What materials is this insert best suited for?
The CPMT080208 NS9530 insert is formulated as a finishing grade for steel; the NS9530 uncoated cermet excels in continuous cuts and small depths of cut on steel workpieces.

How does the insert secure in the holder?
Retention is via the central hole with a cylindrical bore and a one-sided countersink (40°–60°); the rhombic form, relief angle and thickness ensure a repeatable fit in ISO-compatible holders.

Can the insert be used for roughing operations?
This grade and geometry are optimised for finishing; for heavy roughing, a tougher grade or a different geometry would be preferable to withstand higher cutting forces.

What surface quality can be expected with this insert?
Thanks to the sharp cutting edge of the NS9530 uncoated cermet, the insert provides high surface quality in finishing passes when combined with appropriate feeds and speeds.

Is the CPMT080208 compatible with standard ISO CPMT holders?
Yes — compatibility is governed by the ISO form, relief angle, tolerance class, attachment style, size and thickness; the CPMT080208 conforms to ISO specifications for this type.
