✅ Direct ER32 attachment point accepts standard end mills and router bits fast
✅ Compact 125mm diameter frame slides into small workbench gaps easily

💡 Why choose a water cooled spindle motor as a handy shop addition?
Stable rotary drivers spin milling cutters at precise RPMs while liquid channels drain heat away from hot spots.
- Circulating fluid maintains constant coil temperature to prevent insulation breakdown during marathon carving runs
- Ground metal races minimize drag so the motor holds peak wattage when slicing thick oak or marble sheets
- Rigid cast aluminum casing bolts directly to standard X Y Z tables for fast alignment without extra adapters
