SCMT120408 NS9530 Milling Insert — Milling, Tungaloy, 90°

A SCMT120408 NS9530 indexable milling insert for Tungaloy milling systems, optimised for finishing steel in continuous cuts and small depths.

• Cermet grade NS9530 for finishing steel
• Sharp cutting edge for low cutting forces
• Square 12 mm insert, 90° geometry
• Single-sided chipbreaker with central hole

Consistent finishing and why the grade matters

The uncoated NS9530 is a cermet finishing grade designed for steel applications where surface integrity matters. Its composition produces a sharp cutting edge that reduces ploughing and lowers cutting forces, which in turn improves dimensional control and part finish during continuous machining and small depth cuts. For operations that prioritise a high-quality surface over heavy stock removal, this insert delivers measurable gains in first-pass quality and shorter downstream processing.

Stable geometry for secure clamping and chip control

The insert’s square 12 mm form, 4.76 mm thickness and 0.8 mm corner radius provide a balance between rigidity and fine edge geometry. The 7° relief and 90° main angle ensure predictable engagement and repeatable seating in compatible tool bodies, while the cylindrical central hole with a single-sided 40°–60° countersink secures positive clamping and quick indexing. The single-sided chipbreaker supports effective chip formation in continuous cuts, helping to maintain surface quality and reduce the risk of edge damage.

Operational advantages on the shop floor

Using this grade and geometry reduces cutting forces and can extend cutter life by lowering mechanical and thermal loads, leading to reduced tool wear and higher part throughput. Integration into a matched Tungaloy milling system ensures the insert’s benefits are realised; seating, insert geometry and cutter body must be technically compatible for optimal performance. Typical uses include facing, shoulder milling, slotting, high-feed and contour operations where fine finishes and repeatability are required.

FAQ

What materials is this insert suited for?
The SCMT120408 NS9530 insert is an uncoated cermet finishing grade primarily intended for steel machining, optimising surface finish and cutting stability in continuous cuts.

Does the insert fit all Tungaloy milling bodies?
Compatibility requires matching the insert seat and geometry; the SCMT120408 format fits tool bodies designed for SCMT120408 inserts within the Tungaloy system family.

What are the key dimensions to check before use?
Check the 12 mm square size, 4.76 mm thickness and 0.8 mm corner radius, together with the 7° relief and 90° main angle to ensure correct seating and engagement.

How does the chipbreaker and hole design affect performance?
The single-sided chipbreaker aids chip formation in continuous cuts, while the central cylindrical hole with a 40°–60° countersink provides secure clamping and simple indexing during tool changes.

Can this insert be used for high-feed operations?
Yes — depending on the assigned tool family, the insert supports high-feed and contour milling where the cutter body and insert geometry are matched.
