TPMT090208 NS9530 Tungaloy turning insert — triangular ISO finishing grade with 0.8 mm radius

The TPMT090208 NS9530 Tungaloy insert is an ISO-standard triangular turning insert designed for finishing operations on steel, offering a sharp edge geometry and a one-sided chipbreaker for continuous cuts.

• ISO triangular insert for turning
• Uncoated cermet grade NS9530 for finishing
• Sharp cutting edge for high surface finish
• 11° clearance angle for low cutting forces
• Countersunk hole for secure clamping

High-precision finishing with low cutting forces

The insert is manufactured in the NS9530 uncoated cermet grade, optimised for finishing steel with a sharp cutting edge and reduced cutting forces. This combination favours continuous cutting conditions and small depths of cut, delivering a smoother machined surface and consistent dimensional results. For operations where surface integrity and tight tolerances matter, the material pairing and edge geometry reduce the need for secondary finishing, improving process throughput and component quality.

Stable clamping and ISO compatibility for repeatable results

Designed as an ISO-compliant triangular insert, the component features a central clamping hole with a cylindrical hole and single-sided countersink (40°–60°) to secure the insert reliably in compatible external holders or boring bars. The standardised form, size and thickness ensure quick replacement and predictable seating, which supports process stability and reduces downtime related to insert seating and alignment.

Controlled cutting contact for superior surface finish

With an edge radius of 0.8 mm and an 11° clearance angle, the geometry reduces built-up edge and minimises rubbing during finishing cuts. These specifications help maintain a high surface finish while keeping cutting forces low, which is particularly beneficial when machining long, slender workpieces or assemblies that are sensitive to vibration. The one-sided chipbreaker supports chip control under continuous feed conditions, lowering the risk of surface damage from erratic chip flow.

Practical application notes and machining guidance

The insert is specified for turning and should be paired with a suitable holder and torque-controlled clamping to preserve the edge integrity. The one-sided chipbreaker and uncoated cermet grade are best suited to stable setups and steady feeds; choose a matching holder form, free clearance, tolerance class and screw type to ensure full compatibility. For mixed-material runs or interrupted cuts, select an alternative grade or chipbreaker adapted to the specific workpiece material and cutting conditions. Metav Werkzeuge’s technical team can advise on holder selection and recommended cutting data to match the application.

FAQ

What materials is this insert best suited for?
The TPMT090208 NS9530 is formulated as a finishing grade for steel; the uncoated cermet composition gives a sharp edge and low cutting forces suitable for continuous turning of steel components.

Which holders are compatible with this insert?
Compatibility depends on form, clearance, tolerance class, clamping method, size and thickness; the TPMT090208 fits ISO triangular holders designed for 09-size inserts and requires a clamping screw that matches the countersunk hole geometry.

How does the 0.8 mm radius affect surface quality?
A 0.8 mm radius provides a favourable balance between edge strength and smoothness, improving surface finish while maintaining adequate resistance to edge chipping during finishing cuts.

Is coolant required when using the NS9530 grade?
For many finishing operations the NS9530 uncoated cermet performs well under dry and low-coolant conditions due to its sharp edge, but coolant use should be chosen based on material, machine rigidity and cycle specifics.

What is the manufacturer SKU for ordering and traceability?
The manufacturer SKU is TUN6998544 and the article number is 6998544 for the TPMT090208 NS9530 Tungaloy turning insert
