SCMT 09T308 NS9530 – Tungaloy milling indexable insert for finishing applications

SCMT 09T308 NS9530 offers a finishing-grade solution for milling steel with a sharp cutting edge and low cutting forces, designed for use in compatible Tungaloy milling systems

• Precision finishing grade NS9530 for steel
• Square 90° geometry for shoulder and face milling
• 0.8 mm corner radius for repeatable edge stability
• Cylindrical hole with single-sided countersink (40°–60°)

High-precision finishing for steel components

The insert is manufactured as a finishing-grade solution using the NS9530 uncoated cermet substrate, delivering a consistently fine surface quality on steel. The combination of a sharp cutting edge and low cutting forces reduces vibration during light-steel machining, which directly benefits surface integrity and reduces secondary finishing. Compatibility with the matching milling body and correct clamping is essential to obtain the intended performance; the insert is intended for applications where small depths of cut and continuous cutting produce the best results.

Geometry engineered for repeatable shoulder and face milling

A 90° square form factor provides precise corner definition for shoulder and face operations, while the 0.8 mm corner radius balances edge strength with the capacity to produce tight, repeatable profiles. The moderate thickness of 3.97 mm and the square format enable stable seating in the pocket and predictable load distribution under finishing conditions. The cylindrical centre hole with a single‑sided countersink (40°–60°) secures positive clamping and repeatable axial positioning in the cutter body, supporting consistent part-to-part accuracy.

Chip control and cutting behaviour optimised for continuous cuts

Equipped with chipbreaker 23, the insert is tailored for continuous cutting and small depth-of-cut strategies typical of finishing cycles. The chipbreaker geometry promotes slender, controllable chips and prevents re-cutting, which helps maintain low cutting forces and preserves the integrity of the sharp cermet edge. The controlled chip flow also contributes to a superior surface texture and reduces the risk of material build-up on the cutting edge during longer runs.

System compatibility and safe clamping for predictable results

This insert is designed for use in Tungaloy milling systems where the insert seat, geometry and cutter body match technically. Correct selection of clamping screw and underlay—where applicable—ensures secure fixation; the insert’s central hole and countersink arrangement facilitate reliable axial and radial location. For best results, select the correct cutter family and verify seat geometry before assembling; this guarantees the insert works within its intended mechanical and thermal envelope.

When to choose this insert and expected benefits

Choose this insert where high surface quality and low cutting forces are priorities—typical uses include face milling, shoulder milling, slotting and contouring in steel when using finishing parameters. The uncoated cermet substrate excels at producing fine finishes and consistent part tolerances under continuous feeds and small feed per tooth. By matching the insert to an appropriate cutter body and machining strategy, process stability and repeatability are improved, contributing to reliable series production.

FAQ

What materials is this insert intended for?
The SCMT 09T308 NS9530 insert is specified as a finishing-grade uncoated cermet designed primarily for machining steel in finishing operations.

Which milling operations suit this insert best?
The insert is suited to face milling, shoulder milling, slotting and contouring where small depths of cut and continuous feeds are applied to achieve a high-quality surface finish.

How does chipbreaker 23 influence performance?
The chipbreaker 23 promotes controlled chips in continuous cutting, improving surface finish and reducing cutting forces, which is particularly beneficial during finishing passes with the NS9530 substrate.

What must be checked before fitting the insert to a cutter body?
Ensure that the insert seat, geometry and cutter body match technically; confirm the correct clamping screw and underlay if required to guarantee secure, repeatable seating and axial alignment.

Is the insert suitable for interrupted cuts or heavy roughing?
This insert is optimised for finishing and continuous cutting; for heavy roughing or heavily interrupted cuts, a different grade or geometry would be recommended to maintain tool life and process stability.
