Shank milling cutter S520-1TM – 25 mm shank, internal coolant (Teknik Makina)

The Shank milling cutter for R390 17 indexable inserts is designed for secure, coolant-through milling in industrial applications, combining a compact profile with reliable insert retention.

• 25 mm shank diameter
• Internal coolant supply
• Compatible with Sandvik R390 17 inserts

Exceptional rigidity for stable machining

A robust 25 mm shank provides the axial and radial stiffness required for repeatable results in milling cycles. The larger-diameter shank reduces vibration and improves surface finish when compared with thinner tooling, which translates into fewer rework operations and more consistent component tolerances. Designed for conveyors and CNC machines, this cutter supports operations where tool stability directly affects throughput and part quality.

Coolant-through design for longer insert life

The internal coolant feed directs cutting fluid straight to the cutting zone, improving chip evacuation and reducing thermal load on the insert. That direct supply helps maintain cutting-edge geometry for longer periods, extending the service life of the indexable tips and lowering tooling costs per component. In practice, coolant-through tooling reduces the risk of built-up edge and makes coolant delivery more effective under higher feed and speed settings.

Proven compatibility and easy insert handling

Built for use with Sandvik R390 17 indexable inserts, the tool offers the flexibility of a standard insert family while retaining the benefits of a dedicated cutter body. Insert clamping uses a Torx screw M3.5x8.5 secured with a T15 Torx key, enabling straightforward tip changes and quick replacement during set-up. This modularity minimises machine downtime and allows easy optimisation of insert grades for different materials and cutting conditions.

Compact geometry for versatile applications

With an overall length of 150 mm and a 55 mm cutting length, the cutter strikes a balance between reach and stiffness suitable for face and light shoulder milling tasks. The two cutting edges support efficient material removal on intermittent passes while maintaining good surface quality. At a practical mass of 0.536 kg, the tool is simple to handle during tool changes and compatible with common toolholders on milling spindles.
