SPMN 120408 AH120 – ISO square indexable turning insert by Tungaloy, PVD-coated cemented carbide, 11° clearance

The SPMN120408 AH120 is an ISO-standard square indexable insert for turning, engineered for stable external and internal machining where a sharp cutting edge and process reliability are required

• ISO-standard square insert 12 mm
• PVD-coated cemented carbide grade AH120
• 11° clearance angle for stable cutting
• 0.8 mm corner radius for fine finishing

Consistent cutting performance through optimised grade and coating

The combination of a PVD-coated surface and cemented carbide substratum in this insert provides notable wear resistance and edge stability during prolonged turning operations. These material characteristics reduce the frequency of tool changes and contribute to consistent component quality, which is particularly beneficial in repetitive production runs. The design emphasises process security, so machining variations are minimised and surface finish reproducibility improves.

Geometry that balances strength and finish

The ISO-standard square geometry and the specified 11° clearance deliver a reliable cutting stance with low risk of flank rubbing under stable setups. The 0.8 mm corner radius supports fine finishing while still offering sufficient edge strength for medium cutting depths. The square 12 mm format allows multiple usable corners through indexing, extending tool life and lowering per-part tooling cost. Compatibility with standard holders is determined by form, clearance angle, tolerance class, fastening method, size and thickness.

Practical guidance for turning applications

Built for turning—both external and internal—the insert works best in stable, well-clamped set-ups where its sharp cutting edge and PVD layer can fully express their benefits. This variant is supplied without chipbreaker, so parameters should be chosen according to the workpiece material and the rigidity of the machining system; selecting the correct cutting data and a suitable holder is essential to exploit the grade's strength. For finishing passes, adopt lower depths of cut and moderate feed to leverage the fine corner radius.

Integration into an indexable tooling system

As part of an indexable system, the insert functions together with a compatible external holder or boring bar, a support shim or clamp set, and replacement screws as required. The SPMN120408 AH120 design is intended for straightforward replacement and indexing, helping to maintain uptime during production. Identification and ordering are simplified by the manufacturer SKU and article references, which also support orderly tool management and reordering processes.
