Quite possibly the lightest weight ISO30 ATC spindle available at a 7hp power output level.  The RM70 sits in a class of its own.  This model still features our upgraded high rigidity bearing arrangement, with 4 bearings total, and dual P4+ high precision angular contacts in the spindle nose.  The high efficiency fabricated copper rotor and precision wound stator, allow us to pack a ton of power into an incredibly small and lightweight spindle package.
