ERMD1 Extension adapter

  Adapter plate for other drill motors    

When drilling big diameter holes over Ø 600 mm (23.6”)an extension adapter must be used to extend the distance between drill column and spindle, giving more clearance for bigger diameter drills. Each adapter extends the drill unit 90 mm (3.5”) further away from the column, i.e. gives additional clearance for a 180 mm (7”) bigger drill bit.
