TPMT 110308 NS9530 — Turning insert (Tungaloy)

TPMT 110308 NS9530 is a triangular ISO turning insert engineered for finishing steel components with a sharp cutting edge and low cutting forces

• ISO-standard triangular insert for finishing
• Uncoated cermet grade NS9530 for fine finishes
• Sharp cutting edge for low cutting forces
• Cylindrical hole with 40°–60° countersink

Achieve high-quality finishes with cermet precision

The triangular ISO insert is designed for finishing and produces a consistently fine surface finish thanks to the uncoated cermet NS9530 cutting material. Cermet combines ceramic and metallic phases to provide a sharp edge and thermal stability, which reduces built-up edge during continuous turning operations. The result is lower cutting forces and improved dimensional control on turned parts, particularly in steel applications where a smooth final surface is required. Emphasis on stable geometry and a defined corner radius supports repeatable results and reduces the need for secondary finishing operations.

Clear compatibility and simple system integration

Compatibility with toolholders is governed by the insert form, 11° relief, tolerance class, fastening method, nominal size and thickness. The ISO designation and triangular form ensure straightforward integration into standard holders and boring bars that accept TPMT-style inserts. The insert’s cylindrical hole with a one-sided countersink (40°–60°) allows secure clamping and consistent seat location, improving repeatability across index changes. This system-oriented approach simplifies tooling logistics and reduces setup time on the shop floor.

Process advantages and application guidance

Using an uncoated cermet grade NS9530 in finishing provides a balance of sharpness and wear resistance: sharp cutting edges lower cutting forces while the material’s wear characteristics maintain edge integrity during longer continuous cuts. For small depths of cut and light feed finishing passes, this geometry and grade help achieve tight tolerances and high surface quality. Where stability and consistent chip formation are priorities, the TSF chipbreaker supports controlled chip flow, aiding surface integrity and reducing the risk of re-cutting.

Practical notes for handling and set-up

The insert’s 0.8 mm corner radius and 3.18 mm plate thickness contribute to stiffness at the cutting edge, allowing fine but stable finishing passes. When mounting, ensure the matching holder accepts the TPMT form and that clamping screws and underlay plates correspond to the ISO tolerance class to secure contact and minimise vibration. For materials selection: the grade is optimised for steel finishing; cutting parameters should be adapted for continuous cuts and small depths of cut to fully exploit the low cutting force characteristic of the grade.

FAQ

What materials is this insert best suited for? This insert, specified as an uncoated cermet NS9530 grade, is optimised for finishing operations in steel; NS9530 emphasises a sharp edge and low cutting forces suitable for continuous turning.

How does the TSF chipbreaker affect machining? The TSF chipbreaker promotes controlled chip formation and evacuation, which supports consistent surface quality and reduces the likelihood of chip interference during finishing cuts with the TPMT 110308 geometry.

What are the key mounting considerations for this insert? Ensure the toolholder matches the TPMT form, the 11° relief and the plate thickness of 3.18 mm; correct seating and clamping, using compatible underlay plates and screws, are necessary for repeatable accuracy.

Can this insert be used for internal turning? Yes, the geometry and low cutting-force characteristics make the insert suitable for both external and internal turning where finishing and surface quality are required.

How does the 0.8 mm corner radius influence results? The 0.8 mm corner radius balances edge strength and surface finish: it provides stiffness for stable cuts while still enabling fine finishing passes to achieve the desired surface texture.
