SCMT 120412 NS9530 — SCMT120412-PM turning insert by Tungaloy

SCMT120412-PM NS9530 is an ISO square turning insert designed for finishing operations in steel, offering a sharp cutting edge and stable chip formation

• Finishing-grade uncoated cermet NS9530
• Sharp edge for low cutting forces
• Optimised PM chipbreaker for continuous cuts
• ISO SCMT 120412 with 90° geometry

Precision finishing with an uncoated cermet for excellent surface quality

The uncoated cermet NS9530 is engineered as a dedicated finishing grade for steel, delivering a sharp cutting edge that reduces cutting forces and improves stability during light cuts. For shops focused on superior surface integrity, this substrate lowers the risk of torn edges and minimises the need for secondary finishing operations. The material composition and edge preparation are chosen to provide consistent results during steady, continuous machining at small depths of cut.

Predictable process behaviour thanks to ISO geometry and clear specifications

Built to ISO standards, the insert features a square geometry with a 90° included angle and a 1.2 mm corner radius, ensuring repeatable seating and clamping in compatible holders. Compatibility to the toolholder is determined by form, relief angle, tolerance class, clamping and thickness; this insert’s 7° relief angle and 4.76 mm thickness are clearly specified for straightforward tool selection. Such defined parameters enable stable cutting conditions and simplify tool changeovers, reducing setup time and enhancing production reliability.

Chip control and application suitability for efficient finishing cycles

The integrated PM chipbreaker was selected to support continuous cutting and fine feeds typical of finishing passes in steel, promoting short, manageable chips and consistent surface finish. The insert is supplied with a cylindrical hole plus a single-sided countersink (40°–60°) to match common clamping systems, and its compact 12 mm seat size is suitable for both external and internal turning where a high-quality finish is required. The combination of substrate and chipbreaker reduces rework, contributing to improved process economy in precision turning operations.
