S518TM — Shank milling cutter for R390-1704 indexable inserts by Teknik Makina, Ø 40 mm, shank Ø 32 mm

The S518TM is a shank milling cutter designed for use with R390-1704 indexable inserts, offering robust geometry for demanding CNC milling tasks.

• Compatible with Sandvik R390-1704 inserts
• Ø 40 mm cutting diameter
• Shank Ø 32 mm and 45 mm cutting length

Reliable insert system for flexible production

The S518TM is engineered as an indexable insert solution, accepting the widely used R390-1704 style by Sandvik, which allows toolshops to balance economy and performance. The insert is secured with a Torx M3.5x8.5 screw operated with a T15 key, a common and robust clamping method that simplifies tool changes and reduces setup time. This arrangement supports fast replacement of cutting edges, keeping machines productive and tooling costs manageable.

Geometry that stabilises material removal

With a Ø 40 mm cutting diameter and a shank Ø 32 mm, the cutter provides a balance between cutting reach and rigidity; the 45 mm cutting length and 120 mm overall length give defined engagement depth while maintaining stability. The tool features a 90° cutting angle and four cutting edges, which together deliver even load distribution and consistent chip formation. The listed weight of 0.782 kg reflects a solid construction that assists repeatable performance in serial milling applications on CNC machines.

Practical handling and production benefits

Insert clamping with the specified Torx screw provides secure retention and straightforward maintenance, helping to keep throughput high in production environments such as toolrooms and milling centres. As a modular cutting tool, the solution lowers per-part costs because only inserts are replaced, not the entire cutter body. The design is therefore suited to workshops aiming for efficiency, predictable tool life and straightforward inventory management.
