How does the accessory system work with the Digital rotary tool?
The Digital rotary tool uses the same accessories and collet system as the current Dremel 300 Series, MultiPro or other previous rotary tool models. The accessory shank (stem part of an accessory) sizes range from 1/32″ to 1/8″. The collet, a slim aluminum tube with small slots, holds the shank portion of the accessory and will be tightened inside the collet when you tighten the black collet nut on the end of the Digital rotary tool’s output shaft. Use the wrench, provided in your Digital rotary tool kit, if you cannot firmly tighten with your fingers. For harder work load applications (i.e. routing, tile cutting, etc.) please always use the wrench to assure proper tightening.
