S603-1TM – 25 mm shank indexable milling cutter body for R390 18 inserts with internal coolant (Teknik Makina)

A S603-1TM cutter body engineered for insert milling applications, offering a 150 mm overall length and targeted coolant delivery for improved tool life and process reliability.

• Internal coolant for reliable chip evacuation
• Compatible with Sandvik R390 18 inserts
• 25 mm shank for standard toolholders
• 60 mm cutting length, 150 mm overall length

Greater stability and predictable machining results

The combination of a 25 mm shank and a balanced overall length of 150 mm provides increased rigidity compared with smaller shank diameters, which translates into reduced vibration and more consistent surface finish. The tool’s mass (approx. 0.531 kg) contributes to stable rotation at typical milling speeds, helping to maintain dimensional accuracy during interrupted cuts. For workshops and production lines seeking reproducible results, the robust design of this cutter body supports repeatable set-ups and fewer reworks.

Faster indexable insert changes and straightforward maintenance

Designed to accept Sandvik R390 18 indexable inserts, the body simplifies insert replacement and maintenance procedures. Fast clamping is enabled by standard Torx hardware (Torx key T15, screw M4x10), reducing tool change time and machine downtime. The unit holds two cutting edges, permitting economical use of indexable inserts while preserving process flexibility. Clear access to the fixing screws and a logical arrangement of the insert seats make routine checks and regrinds efficient for workshop staff.

Integrated coolant for extended tool life and stable cutting

The internal coolant channel directs lubricant and coolant close to the cutting zone, which promotes heat dissipation and improved chip control. This targeted coolant supply supports longer insert life and can help stabilise cutting forces in heavy-duty operations, especially where consistent temperature control matters. The tool body is therefore suitable for organised production environments that prioritise tool longevity and operational uptime while maintaining simple handling and quick insert swaps.
