The perfect solution to enlarge existing holes professionally in seconds. The SRDA2 avoids the use of separate A1 & A2 arbors with this Innovative 2-in-1 tool.
Simply screw the desired hole saw onto the arbor. Screw the old size hole saw using the longer threads. Then lock in the longer pins to stop the hole saw seizing. Finally easily and professionally enlarge your hole.
This is both an A1 & A2 arbor that will fit traditional hole saws 14 mm – 210 mm allowing for a wider range of applications.
