TPMT 110308 NS9530 — ISO triangular turning insert with PS chipbreaker (Tungaloy)

The TPMT 110308 NS9530 is an ISO-standard triangular insert for turning, optimised for finishing steel with a sharp cutting edge, small depths of cut and continuous machining.

• ISO-standard triangular insert, 11° relief
• Uncoated cermet for finishing
• 0.8 mm corner radius for fine profiles
• Cylindrical hole with countersink for secure clamp

Fine finishing and reduced rework

The NS9530 grade is an uncoated cermet designed specifically as a finishing grade for steel, offering a sharp cutting edge that reduces ploughing and lowers cutting forces. This results in a consistent surface quality on external and internal profiles and minimises the need for subsequent manual finishing. For applications with small depths of cut and continuous cutting, the geometry and microstructure of the grade help secure predictable dimension tolerance and repeatable surface results, making it suitable where part appearance and dimensional accuracy are priorities.

Secure clamping and easy indexing

ISO compliance and the insert’s geometry simplify toolholder selection: compatibility is determined by shape, relief angle, tolerance class, clamping method, size and thickness. The triangular form provides three indexing edges, enabling quick rotation and maximising usable edges per insert. The cylindrical hole with a single-sided countersink (40°–60°) ensures reliable location and seating in the pocket, while the 3.18 mm thickness contributes to stable clamping and vibration resistance during finishing passes.

Productivity through predictable performance

A 0.8 mm corner radius and the PS chipbreaker combine to deliver stable chip control in light finishing cuts without aggressive cutting forces. The 11° relief angle reduces rubbing on the flank and helps maintain cutting-edge sharpness, supporting longer intervals between indexings on continuous operations. As a result, cycle times remain consistent and scrap due to surface defects is reduced. For manufacturers seeking high first-pass quality and lower rework rates, these inserts contribute directly to process efficiency and predictable production output.

FAQ

What materials is this insert intended for?
The TPMT 110308-PS NS9530 is formulated as a finishing grade for steel and is recommended where a sharp edge and high surface quality are required.

How many usable edges does the insert offer?
The triangular form provides three cutting edges per insert; the ISO geometry and the cylindrical hole with countersink support secure seating and reliable indexing.

Is the insert coated and how does that affect use?
This insert uses an uncoated cermet grade (NS9530), which promotes a sharp edge and excellent surface finish in finishing applications over coatings that are typically chosen for roughing or higher thermal loads.

Which feature most influences surface finish in continuous cuts?
A combination of the NS9530 cermet grade, the 0.8 mm corner radius and the PS chipbreaker stabilises chip formation and reduces cutting forces, directly improving surface quality on continuous finishing passes.
