Shaft milling cutter S594-2TM — 21 mm diameter with internal coolant (Teknik Makina)

A robust Shaft milling cutter S594-2TM designed for high‑precision milling tasks using R390 11T3 indexable inserts, suitable for production environments and workshop milling operations.

• 21 mm cutting diameter, compact design
• Internal coolant for improved chip evacuation
• Compatible with R390 11T3 inserts (Sandvik)
• 20 mm shank, 150 mm overall length

Improved process stability with compact diameter and proven insert system

The compact 21 mm cutting diameter delivers a balance between rigidity and accessibility, making the tool effective in confined setups and multi‑axis stations. Compatibility with R390 11T3 indexable inserts ensures a wide choice of cutting grades and geometries, which reduces tool change frequency and keeps production moving. The three‑edge configuration provides stable cutting progression; wear is localised to the insert so downtimes are minimised and repeatability across batches is enhanced.

Enhanced cooling and chip control for longer tool life

Equipped with internal coolant, the cutter channels cutting fluid directly to the cutting zone to improve lubrication and temperature control. This targeted cooling reduces thermal load on the insert and holder, promoting more consistent tool life and better surface integrity. For manufacturers looking to raise throughput without compromising finish, the internal supply supports higher metal removal rates and aids reliable chip evacuation from narrow pockets.

Practical mounting and service features for efficient handling

The tool is supplied with a 20 mm shank and a total length of 150 mm, with a cutting length of 50 mm, enabling secure clamping in standard toolholders and giving sufficient reach for many slotting and face‑milling tasks. The cutter uses a Torx T8 key and M2.5×5.5 screws for insert clamping, which simplifies replacement and repeatable seating. At 0.366 kg it combines manageable handling with the mass needed to dampen chatter in bench and production milling operations.

Workflow advantages through interchangeable inserts and supplier compatibility

Designed as an insert milling tool, this cutter reduces per‑part machining costs by allowing worn cutting edges to be replaced without switching the whole body. Compatibility with Sandvik inserts and standardised fixing hardware means inserts are widely available, simplifying procurement and stocking. Teknik Makina’s manufacturing tolerances ensure concentricity and balance are maintained, which improves cycle consistency and reduces inspection effort on repetitive batches.
