Shank cutter for R390-11T3 indexable inserts — compact, rigid milling with Sandvik compatibility

Shank cutter for R390-11T3 indexable inserts designed for secure clamping and precise face or slot milling where R390-11T3 inserts are specified

• 20 mm shank diameter
• 50 mm cutting length
• Compatible with Sandvik R390-11T3 inserts
• Three cutting edges for stable milling

Greater process stability through a compact, rigid design

The combination of a 20 mm shank and a balanced 200 mm overall length offers a high level of rigidity that reduces vibration during cutting, directly improving surface finish and tool life. With a 50 mm cutting length and a 90° cutting angle, the tool is engineered for repeatable material removal in operations that demand consistent geometry. Using indexable inserts such as the R390-11T3 eliminates regrinding and simplifies maintenance, translating technical features into measurable time savings on the shop floor.

Fast insert changes and secure clamping cut downtime

Maintenance and insert replacement are simplified by the Torx screw M2.5x5.5 and the compatible T8 key, ensuring repeatable clamping torque and reduced setup error. The cutter’s three cutting edges distribute cutting forces evenly, which lowers the risk of premature insert failure and keeps machines productive for longer. These practical design elements support a rational investment case: fewer interruptions, predictable maintenance cycles, and reduced tooling inventory when standardised on widely available inserts.

Integrates seamlessly into existing tooling systems

Designed around the widespread R390 series, the tool allows shops to keep a compact insert inventory while benefiting from a proven insert geometry by Sandvik. The combination of standard interfaces and a familiar fastening system enables quick retrofitting into existing holders and toolpaths. For production planners, this means faster changeovers and improved throughput without the need for specialised holders or bespoke adjustments — a clear operational advantage in mixed-production environments.

Practical reliability for everyday workshop use

Weighing 0.48 kg and finished to industry tolerances, the cutter offers a practical balance between handling convenience and machining robustness. The apparent simplicity of the tool belies careful engineering: a standardised connection to commonly used inserts provides peace of mind and predictable performance in repetitive milling tasks. Where traceability and repeatability matter, this combination of features supports consistent component quality and fewer unexpected rejects.
