TPMT110208-PF NS9530 ISO turning insert — uncoated cermet finishing grade by Tungaloy

TPMT110208-PF NS9530 is an ISO-format triangular indexable insert designed for finishing turns on steels, providing sharp cutting geometry and consistent surface quality

• ISO-standard triangular turning insert
• Cermet finishing grade NS9530
• Sharp edge for high surface finish
• Cylindrical hole with 40°–60° countersink

Consistent finishing performance for steel turning

The insert combines an uncoated cermet substrate with a finishing geometry intended to reduce cutting forces and enhance surface quality. The NS9530 grade delivers a sharp cutting edge and good wear resistance in continuous cutting conditions, which supports predictable component tolerances and repeatable results. By selecting a finishing cermet, the machining process benefits from reduced built-up edge and improved dimensional stability during small depths of cut, making it particularly suitable for final passes where surface integrity is critical.

Precise geometry and secure clamping for repeatability

Dimensional and geometric details determine compatibility with holders and influence process stability. The triangular profile with a 60° included angle, 0.8 mm corner radius and 11° relief angle provides a defined contact geometry that eases toolpath planning and reduces vibration risk during stable turning. The insert features a cylindrical centre hole with a one-sided 40°–60° countersink, ensuring reliable clamping in standard ISO turning holders. The 2.38 mm thickness contributes to bending resistance while allowing the insert to sit securely in the pocket for repeatable indexation.

Material behaviour and application recommendations

As a dedicated finishing grade for steel, this insert excels in continuous cuts and is optimised for small feed and depth settings. The PF chipbreaker geometry promotes predictable chip evacuation for finishing operations and pairs well with the sharp cermet edge to maintain low cutting forces and high surface finish. Use the insert in stable setups with appropriate holder rigidity and moderate cutting speeds tailored to cermet behaviour; this reduces thermal shock and preserves edge sharpness for longer productive life. For mixed or interrupted cuts, assess stability before proceeding to preserve the finishing edge.

Integration into the machining system and replacement logic

The insert is part of a system comprising the ISO insert, a matching external holder or boring bar, a seat/support and fastening hardware. Compatibility hinges on insert form, relief angle, tolerance class, attachment method and size; confirm holder seat geometry matches the TPMT110208-PF profile to ensure correct seating. When replacing inserts, follow the holder torque recommendations and inspect the seat for debris to maintain alignment. Using the correct chipbreaker and grade helps to avoid unnecessary overcutting and supports consistent cycle times across batches.

FAQ

What materials is this insert intended for? The TPMT110208-PF NS9530 is a finishing-grade uncoated cermet insert intended primarily for machining steel, offering low cutting forces and improved surface finish.

How does the PF chipbreaker influence machining? The PF chipbreaker on the insert promotes controlled chip formation during finishing operations, which supports consistent surface quality when using the TPMT110208-PF NS9530 in continuous cuts.

Which holders are compatible with this ISO insert? Compatibility depends on holder form, relief angle and size; the insert follows ISO norms for triangular turning inserts, so it requires an ISO-compatible external holder or boring bar that accommodates the 11° relief and the central hole with a countersink.

What are the key dimensions to check when replacing an insert? Check the insert thickness (2.38 mm), corner radius (0.8 mm), and the included angle (60°) to ensure correct seating and toolpath fidelity with the intended holder when using the TPMT110208-PF NS9530.

Can this insert be used for interrupted cuts? The grade is optimised for finishing and continuous cuts; for interrupted cutting conditions, evaluate workpiece stability and cycle parameters as the sharp cermet edge is more sensitive to shock.
